Introduction The FX-850 and FX-1050 printers combine all the well-known features of previous Epson® 9-pin printers with many features normally exclusive to costly 24-pin printers.
Options A variety of printer options are available for use with FX printers. For detailed information on the installation and use of these options, see Chapter 7. Single-bin and dual-bin cut sheet feeders A cut sheet feeder gives you easier and more efficient handling of single sheet paper. Up to 150 sheets of standard bond paper can be fed automatically into the printer without reloading. This unit also can automatically feed envelopes.
Chapter 4 contains information designed to help you get the most from your printer. This section includes advice on the use of software, printer commands, graphics, and user-defined characters. Also, see Chapter 8 for a summary of printer commands. If the printer does not operate properly or the printed results are not what you expect, see Chapter 6 for a list of possible problems and recommended solutions.

Unpacking the Printer As you unpack the printer, check that you have all the parts shown below and that none has been damaged during transportation. Note: You’ll find the platen knob in a piece of the foam packing. After removing the parts, store the packaging materials in case you ever need to transport your printer.
Removing the protective materials The printer is protected during shipping by a print head protector, two locking tabs, and two screws. These protective items must be removed before you turn on the printer. After removing these items, store them with the other packaging material. 1. Remove the printer cover. 2. Remove the print head protector.
3. Remove the left and right locking tabs. 4. Slide the print head to the middle of the printer. Then, use the enclosed cross-head screwdriver to unscrew and remove the two red screws. WARNING: Be sure to remove all protective materials before you turn on the printer.
Choosing a Place for the Printer When you select a location for your printer, keep the following in mind: l Place the printer on a flat, stable surface. l Place the printer close enough to the computer for its cable to reach. l l Leave adequate room around the printer to allow for easy operation and maintenance. Use a grounded outlet; do not use an adapter plug. The illustration below shows a good printer setup.
WARNING: l l l l Avoid locations that are subject to direct sunlight, excessive heat, moisture, or dust. Avoid using electrical outlets that are controlled by wall switches or automatic timers. Accidental disruption of power can wipe out information in both your computer’s memory and your printer’s memory. Avoid using outlets on the same circuit with large motors or other appliances that might disturb the power supply.
1. Insert the knob into the hole on the printer’s side and rotate it until it slips onto the shaft. 2. Push firmly on the knob until it fits against the printer case. Caution: Never use the platen knob to adjust the position of the paper except in the case of a paper jam. Only use the platen knob when the printer is turned off.
Installing the ribbon cartridge Follow these steps to install the ribbon cartridge: 1. Slide the print head to the middle of the printer. Caution: Never move the print head while the printer is turned on because this can damage the printer. Also, if you have been using the printer, the print head may be hot; let it cool for a few minutes before touching it. 2. Remove the ribbon cartridge from its box and remove the plastic wrapper.
3. Turn the ribbon-tightening knob in the direction of the arrow. This removes any excess slack in the ribbon and makes it easier to install. 4. Hold the ribbon cartridge by its handles and push it firmly down into position, making sure the plastic hooks fit into the printer. (The FX-850 has only one handle in the center of the ribbon cartridge.) Press lightly on both sides of the cartridge to be sure the hooks are properly inserted.
5. Use a pointed object, such as the tip of a pencil, to guide the ribbon between the print head and ribbon guide while you turn the ribbontightening knob to help feed the ribbon into place. 6. Slide the print head from side to side to make sure it moves smoothly. Also make sure the ribbon is not twisted or creased.
Attaching the paper guide The paper guide functions to feed the paper smoothly and efficiently. Follow these steps to install the paper guide: 1. Place the paper guide on the printer. 2. Raise the paper guide until it locks into place.
3. Now reinstall the printer cover by fitting the legs of the cover into the notches at the front of the printer. 4. Close the printer cover. Testing the Printer Now that your printer is fully assembled, you can use the built-in self test function to see that the printer is working correctly even though it is not connected to a computer. Be sure to perform this test to check that your printer is operating properly.
Plugging in the printer Follow these steps to plug in the printer: 1. Be sure the printer is turned off. 2. Plug the power cable into a properly grounded electrical outlet. WARNING: Whenever you turn off the power, wait at least five seconds before turning it back on. Rapid switching on and off can damage the printer. Loading a sheet of paper Next, you need to load a sheet of paper that is letter size (if you have an FX-850) or 14 inches wide (if you have an FX-1050).
2. Be sure that the paper release lever is pushed back to the single sheet position. 3. Move the left edge guide so it locks in place next to the arrow on the paper guide.
4. Adjust the right edge guide to match the width of your paper. Next, slide a sheet down between the edge guides until it meets resistance. 5. Press the LOAD/EJECT button once to automatically load the Paper. If the platen turns without loading the paper, remove the Paper completely and re-insert it more firmly; then press the LOAD/EJECT button again.
Running the self test The self test can be run in the high-speed draft mode, the normal draft mode, or near letter quality (NLQ) mode. Follow the steps below. 1. Load a sheet of paper as described above. WARNING: Never run the self test using paper that is narrower than 8¼ inches if you have an FX-850, or 14 inches if you have an'FX-1050, because you may seriously damage the print head. 2. Turn off the printer. 3.
Note: To run the self test in high-speed draft mode, you must choose that mode as described in Chapter 3. When Roman or Sans Serif is selected with SelecType, the self test runs in the NLQ mode even if you press the LINE FEED button. 4. The self test continues until the paper runs out or until you press the ON LINE button. To stop the test temporarily, press the ON LINE button to take the printer off line. 5. To end the self test, be sure the printer is off line.
Part of a typical self test in NLQ mode is shown below: 3. To end the self test, press the ON LINE button to take the printer off line. Then press the LOAD/EJECT button to eject the paper, and turn off the printer. Connecting the Printer to Your Computer If the self test printed correctly and your printout looked like the one shown, you are now ready to connect your printer to the computer. Your FX printer has a Centronick®-compatible parallel interface.
2. Plug the cable connector securely into the printer. 3. Squeeze the wire clips together until they lock in place on either side of the connector. Note: For your printer to work properly, this connection must be secure.
4. If your cable has a ground wire, connect it to the ground connector beneath the interface connector. 5. Plug the other end of the cable into the computer. (If there is a ground wire at the computer end of the cable, attach it to the ground connector at the back of the computer.

Using Single Sheets Your printer can handle a wide range of paper sizes up to a maximum width of 10.1 inches on the FX-850 or 14.4 inches on the FX-1050. Always make sure that your printing is confined to the size of paper you are using. Never print on the platen (black roller). If you do most of your printing on single sheets, you may find it more convenient to install the optional cut sheet feeder.
3. Stand the paper guide in an upright position and align the left edge guide with the arrow on the paper guide. (You may want to change this position later, depending on the margin settings of your application program.) 4. Adjust the right edge guide to fit the size of the paper. 5. Slide the paper down between the edge guides until it meets resistance. At this point, the PAPER OUT light turns off. 6. Press the LOAD/EJECT button to automatically feed the paper to the loading position.
If the platen (black roller) turns but the sheet does not load, remove the sheet completely from the printer. Then make sure the paper release lever is pushed back. Press the paper a bit more firmly into place and try again. To eject the paper, press the ON LINE button to take the printer off line, and press the LOAD/EJECT button.
3. Release the sprocket lock levers by pulling each lever forward. 4. Slide the left sprocket unit all the way to the left and lock it in place.
5. Next, slide the right sprocket unit to match roughly the width of your paper. (Do not lock it.) 6. Slide the paper support to a point midway between the sprocket units. 7. Open both sprocket covers.
8. Fit the first four holes in the paper over the pins of the sprocket units as shown below. Then close the sprocket covers. 9. Slide the right sprocket unit to a position where the paper is straight and has no wrinkles, and then lock it in place. 10. Reattach the paper guide as shown below.
Caution: When using continuous paper, always make sure that the edge guides are pushed together. 11. Close the printer cover and turn on the printer. 12. Press the LOAD/EJECT button to feed the paper to the loading position. The printer remembers this position and advances each page to the same position. 13. Press the ON LINE button to put the printer on line so that it can accept data.
Positioning your continuous paper supply Three common ways of positioning your printer and continuous paper supply are shown below. It’s important to keep your paper supply aligned with the tractor so that the paper feeds smoothly into the printer.
Switching Between Continuous and Single Sheets Even with continuous paper loaded in the printer, you can easily switch to single sheet printing without removing the continuous paper from the tractor. To switch from continuous paper to single sheets, follow the steps below. 1. Open the printer cover and press the ON LINE button to take the printer off line. 2. Remove your printed document.
3. Press the LOAD/EJECT button to feed the continuous paper backward out of the printer and into a standby position. The paper is still attached to the tractor, but is no longer in the paper path. The PAPER OUT light comes on when the paper is completely out of the paper path. Note: Pressing the LOAD/EJECT button once may not feed the paper back enough to reach a standby position. If the PAPER OUT light does not come on, press the LOAD/EJECT button again.
5. Stand the paper guide upright, and adjust the edge guides to roughly match the width of your paper. 6. Close the printer cover. Next, slide the paper between the edge guides until it meets resistance. At this point, the PAPER OUT light turns off. 7. Press the LOAD/EJECT button to automatically feed the page to the loading position.
8. Press the ON LINE button to put the printer on line. Switching back to continuous paper To switch back to printing with continuous paper, first eject the single sheet of paper and take the printer off line. 1. Open the printer cover. Lower the paper guide onto the back of the printer. 2. Pull the paper release lever forward to the continuous paper position. 3. Press the LOAD/EJECT button to feed the paper to the loading position. 4. Press the ON LINE button to put the printer on line.
Adjusting the Loading Position The loading position is the position of the paper when it has been automatically loaded by the printer. This position is important because it determines where the printing begins on the page. If the printing is too high or too low on the page, you need to change the loading position using the micro-adjustment feature described in the next section. Until the loading position is reset, the printer remembers the position and uses it as a reference point for feeding the paper.
This section describes using micro-adjustment to change the loading position, but you can adjust the short tear-off position the same way. See the next section on using short tear-off for more information. To perform micro-adjustment of the loading position, first load your paper, and then press the ON LINE button to put the printer on line. The ON LINE indicator light starts to flash. While this light is flashing, you can use the FORM FEED and LINE FEED buttons for micro-adjustment.
The short tear-off function operates as follows: 1. The perforation at the end of the last printed page feeds to the tear-off edge of the printer cover. 2. Tear off the page using the printer cover’s tear-off edge. 3. If you need to adjust the position of the perforation to meet the tearoff edge, use micro-adjustment. This feature adjusts your tear-off position only when you use it immediately after short tear-off. First, make sure that the printer is on line and the ON LINE indicator light is flashing.
You can leave the short tear-off feature turned on (DIP switch 1-5 off) even when you are using single sheets. When you move the paper release lever to the single sheet position, short tear-off is disabled. Printing on Special Paper In addition to using single sheets and continuous paper, your printer can also print on a wide variety of paper types, including multi-part forms and labels. You can even feed envelopes, either manually or with the optional cut sheet feeder.
For printing on special types of paper, see the table below. It gives you general guidelines for selecting the right paper thickness lever position to match your paper. Paper Type Paper (single sheets or continuous) Thin paper Multi-part paper 3-sheet 4-sheet Labels Envelopes Air mail Plain Bond (20 lb.) Bond (24 lb.) Lever Position 2 2 3 4 3 3 or 4 5 6 Always return the lever to position 2 when you go back to printing on ordinary paper.
You load continuous multi-part paper the same way that you load continuous paper. See the section on loading continuous paper in this chapter for details. The only difference is that you need to adjust the paper thickness lever to suit the thickness of your paper before loading. See the table above for the correct paper thickness setting. Labels If you need to print labels, always choose the type mounted on a continuous base sheet provided with sprocket holes for use with the tractor.
You can also feed envelopes with the optional cut sheet feeder. See the section on the cut sheet feeder in Chapter 7. Before loading envelopes into the cut sheet feeder, you need to adjust the paper thickness lever. See the table showing envelope types and recommended lever positions on page 2-18. WARNING: When printing on envelopes, be sure that your application program settings keep the printing entirely within the printable area of the envelopes as shown below.

Operating the Control Panel The buttons on the control panel let you control many of the printer settings. The control panel also has indicator lights so you can check the current status of the printer’s various settings. Lights POWER On when the power switch is on and power is supplied. READY On when the printer is ready to accept input data. Flickers when receiving data. PAPER OUT On when the printer is out of paper or when continuous paper is in the standby position.
Buttons ON LINE This button controls the printer’s on line/ off line status. When on line, the printer can receive and print data. FORM FEED Off line: press this button to eject a single sheet of paper or advance continuous paper to the top of the next page. On line: you can use the micro-adjustment feature by pressing this button to advance the Paper. LINE FEED Off line: press this button to feed the paper one line or hold it down to feed the paper continuously.
SelecType The settings you select using the SelecType panel remain valid even after you turn off, reset, or initialize the printer. FONT Press this button to select draft, near letter quality Roman, or near letter quality Sans Serif. The indicator light shows which font has been selected. CHARACTERS PER INCH Press this button to select the characters per inch (cpi). You can choose 10 CPI , 12 CPI, or PS (proportional). The indicator light shows the selected character spacing.
Microadjustment By pressing the FORM FEED and LINE FEED buttons immediately after loading paper or using short tearoff, you can make fine adjustments to the loading and short tear-off positions. See the section on microadjustment in Chapter 2 for more information. Data dump By holding down both the FORM FEED and LINE FEED buttons while you turn on the printer, you can turn on the data dump mode. This feature allows advanced users to diagnose many problems.
DIP switch functions The tables below describe the DIP switch functions. The page numbers refer you to the page on which each printer feature is described. The shaded settings are the preset factory settings.
International character sets Default character set When DIP switch 1-1 is on, the user-defined character set is the default. User-defined characters are maintained in printer memory even when the power is turned off, so the user-defined character set can be selected simply by setting this switch to on. However, when this switch is on, new user-defined characters cannot be defined. See Chapter 4 for more information on user-defined characters. This switch is effective only in the Epson ESC/P mode.
still print text if you have selected the Extended Graphics set. Also, you can still print italics if you use the proper software command. If your printer is in IBM emulation mode (DIP switch 1-4 on), the graphics characters are available no matter which character table you select. The printouts below show which characters are printed in each table. italics Epson Extended Graphics Note: You may need to use the ESC 6 command to print some of the Extended Graphics characters. See Appendix B.
International character set Selecting an international character set provides you with the characters used in other languages. To obtain the desired international character set, set switches 1-6, 1-7, and 1-8 according to the DIP switch table on page 3-7. The following table shows the characters that differ in each international character set.
Cut sheet feeder mode When DIP switch 2-2 is on, you can use your printer’s optional cut sheet feeder. See Chapter 7 for more information on using a cut sheet feeder with your printer. Skip over perforation When DIP switch 2-3 is on, a one-inch margin is provided between the last line printed on one page and the first line printed on the next page. When using continuous paper, this feature causes the printer to stop printing, skip over the perforation, and then resume printing.
Using SelecType You can use the SelecType control panel to choose fonts, pitches, and condensed printing. The settings you select using the SelecType panel remain valid even after the printer is turned off, reset, or initialized. However, commands from your software application program temporarily override the SelecType settings.
The high-speed and normal draft modes use fewer dots per character for faster printing. This makes them ideal for rough drafts and editing work. The only print enhancements that can be combined with high-speed draft are underline and double-strike. If other enhancements are selected, highspeed draft is temporarily ignored and replaced by normal draft. Roman and Sans Serif are near letter quality (NLQ) fonts.
Note: Proportional spacing and condensed mode cannot be combined. If you select both, only proportional spacing works. If SelecType does not work Some application programs are designed to control all typestyle functions. These programs cancel all previous typestyle settings by sending certain software commands before printing. Because these commands cancel SelecType settings, you should use the program’s print options function instead of SelecType to select your typestyles.
The double-wide mode doubles the width of any size characters. This mode is useful for such purposes as emphasizing headings in reports and making displays, but is usually not suitable for large amounts of text. T h i s i s d o u b l e - w i d e . Another mode for headings and other special uses is double-high: This is double-high. Because of its height, you must leave a blank line above a line of doublehigh printing. Otherwise, the double-high letters will overlap the letters on the previous line.
In double-strike mode, the printer prints each character twice, the second time slightly below the first, making the text bolder. For even greater boldness, you can combine emphasized and double-strike. (Double-strike cannot be combined with NLQ mode, however.) Italic printing You can use italic characters for special emphasis or as an alternative typeface. ESC 4 turns on the italic mode even if the current DIP switch setting is set to the Epson Extended Graphics character table.
The format of the Master Select code is shown below: ASCII: Decimal: Hexadecimal: ESC 27 1B ! 33 21 n n n To send the Master Select codes to your printer in a decimal format, for example, you send the codes 27, 33, and then whatever value you choose for the variable n. The variable n is a number that identifies the typestyle or combination of typestyles. To find the value of n, look at the Master Select table below and add up either the decimal or hexadecimal numbers for the features you want.
After calculating the value of n, you use the Master Select command to send the value to the printer. To send the Master Select command for double-wide, 12 cpi, and double-strike, you would use the decimal codes 27, 33, and 49. ASCII: Decimal: Hexadecimal: ESC 27 1B ! 33 21 1 49 31 Consider these things when you use the Master Select command: • Master Select cancels any of the listed features that you do not set.

Using the FX with Application Programs Now that you’ve set up and tested the printer, you need to start using it with your application programs. Most application programs let you specify the type of printer you’re using so that the program can take full advantage of the printer’s features. Many programs provide an installation or setup procedure that presents a list of printers to choose from. If your application program has a printer selection menu, use the instructions below.
A quick test After setting up your application program, print a sample document to make sure the program and the FX are communicating properly. If the document doesn’t print correctly, recheck the program’s printer selection and installation procedure. If you’re still having trouble printing, consult the troubleshooting section in Chapter 6. Using word processors Word processors usually let you use a fixed set of printer features by placing markers around the text to be altered.
panel. The table below shows you many characters you can fit on a line using these options. If your spreadsheet asks the number of columns your printer can print, decide which mode you will use and supply the appropriate number from this table. Typestyle Normal (10 cpi) 12 cpi Condensed 12 cpi condensed FX-850 FX-1050 80 137 96 137 233 160 272 163 Unlike word processors, spreadsheet programs usually don’t let you change printer commands within a spreadsheet.
Using graphics software The FX is capable of producing finely detailed graphic images. Although the section on graphics later in this chapter gives specific information on the graphics commands, the easiest way to take advantage of the FX’s capabilities is with one of the many graphics programs available. When buying graphics software, always make sure the program has an option to print on an FX printer.
your printer and other peripherals. These ASCII characters do not usually have corresponding keys on the keyboard and cannot be printed as characters by your printer. Escape sequences Although there are more than 30 control codes available to control the operation of your printer, many more codes are required to run today’s sophisticated printers. Therefore, ASCII codes are grouped in sequences to represent certain functions.
commands that your printer recognizes are listed in the Command Summary in Chapter 8 and on the Quick Reference card at the back of this manual. Using the Command Summary The commands listed in the Command Summary in Chapter 8 consist of various combinations of ASCII codes. You can use either the ASCII characters or their decimal or hexadecimal equivalents. For example, the command to turn on subscript is ESC S1 in ASCII characters.
Dot Graphics The dot graphics mode allows your FX printer to produce pictures, graphs, charts, or almost any other pictorial material you can devise. Because many commercial software programs use graphics, you may be able to print pictures and graphs like the ones on this and the following page simply by giving your software a few instructions.
The quickest and easiest way to print graphics on your printer is to use a commercial graphics program. With such programs you usually create an image on your monitor and then give a command to send the image to the printer. If you use commercial software that produces graphics, all you need to know about dot graphics is how to use the software. If, on the other hand, you wish to do your own programming or merely wish to understand how the FX prints graphics, read on.
The print head is able to print graphics in addition to text because graphic images are formed on the FX about the same way that pictures in newspapers and magazines are printed. If you look closely at a newspaper photograph, you can see that it is made up of many small dots. The FX also forms its images with patterns of dots. The images printed by the FX can be as finely detailed as the ones at the beginning of this section.
the same time, add up the numbers of the pins and send the sum to the printer. Therefore, with these labels for the pins, you fire the top pin by sending 128. To fire the bottom pin, you send 1. If you want to fire only the top and bottom pins, you simply add 128 and 1, and send 129. By adding the appropriate label numbers together, you can fire any combination of pins. The figure below shows three examples of how to calculate the number that fires a particular pattern of pins.
The command to enter singledensity graphics mode is ESC K nl n2. In BASIC the command is given in this format: LPRINT CHR$(27);"K";CHR$(nl);CHR$(nZ); In this command, ESC K selects single-density graphics, and nl and n2 specify the number of columns to reserve for graphics. Column reservation numbers The graphics command requires more than one number to specify how many columns to reserve because although one line can use thousands of columns, the FX does not use numbers larger than 255 (decimal).
The first line of the program specifies single-density graphics for 40 columns: l00 LPRINT CHR$(27);"K";CHR$(@);CHR$(g); The second line is the data that is printed as pin patterns. It uses the number 74 to produce one of the patterns shown above. The FOR-NEXT loop sends 40 columns of data. Here is the second line of data: 200 FOR X=1 TO 49: LPRINT CHR$(74);: NEXT X That is the whole program.
The program is listed below. The lines inside each pair of FOR and NEXT statements have been indented so that you can see how the program works; the spaces are not needed for the program to run. 100 ll0 120 130 l40 150 WIDTH "LPTl:", 255 LPRINT CHR$(27);"A";CHR$(8); FOR R = 1 TO 6 LPRINT CHR$(27);"K";CHR$(l00);CHR$(@); FOR X = 1 to 50 LPRINT CHR$(17@);CHR$(85); NEXT X: LPRINT 160 170 NEXT R 180 LPRINT CHR$(27);"@" If you run the program, you will see how it combines six print lines into a pattern.
5. The last important thing to do is to reset the printer to its default settings, including the normal line spacing (line 180). Notice that the graphics command (ESC K) can be in effect for only one print line. To print more than one line of graphics, the graphics command must be issued before each line. Density varieties Although all the examples so far in this section have been in the singledensity graphics mode, there are seven other eight-pin densities and two that use all nine pins.
prints dots in only half the possible dot positions in any one row. The higher density means that the resolution of the pattern is better than in single-density mode. When you design patterns in these two modes, however, you must make sure that no dots overlap. Reassigning a graphics mode Another graphics command lets you assign a different eight-pin graphics mode to one of the specific eight-pin graphics commands.
High-speed Single Double In this figure you can see the main rules for graphic design in the three densities: l l l In single-density no dots can be placed on vertical lines, In high-speed double-density, dots can be placed on vertical lines, but no dots can overlap. In double-density, dots can be placed on vertical lines, and they can overlap. Now look at the high-speed double-density design below. It should point you in the right direction for your own work.
After plotting the dots on a grid, you calculate the numbers for each pin pattern by dividing the design grid into separate print lines. For the arrow design, the grid was divided into two lines, each seven dots high. Then each column was examined to calculate the graphics data. The results for the first line are shown below. The pm values are on the left and the sums at the bottom of each column. 128 64 32 16 8 4 2 1 The numbers for the second line were calculated in the same way.

characters or simply supplies you with sets of characters already created. Also, some popular commercial software programs take advantage of the printer’s user-defined character function to enhance printouts. These characters are sometimes called download characters. Defining your own characters The printout below displays a few such characters to give you an idea of what can be done, but remember that since these characters are truly user-defined, you can create whatever you need or want.
Suppose you want to print the scientific symbol for the planet Mercury. Although the FX has a number of special symbols, that is not one of them. First, use a grid like the one below to plan where to place the dots. 123456789 Because the last two columns are reserved for the space between characters, they are not included in the grid. And since most characters do not use the bottom two rows, there is a heavy line to indicate the usual lower limit for an FX character.
First definition program The next few sections explain the steps used to create the symbol for Mercury. The figure below shows the grid used to design the character. 123456789 Once you have drawn your dots on the grid, type the following BASIC program.
Running the program Now run the program. For each of the nine columns, the program asks for the numbers of the rows in which you want dots to appear. Enter the row numbers one at a time, pressing the Enter key after each one. When you have entered all the numbers for a column or when you want no dots in a column, press Enter without a number. Remember that the vertical lines in the grid are the even-numbered columns.
NLQ. Your printout also gives you nine numbers, which you use in the next program. You should get the printout you see below: YOUR CHARACTER I N 10 CPI: I N DOUBLE-WIDE EMPHASIZED 1 0 CPI : I N NLQ YOUR DATA NUMBERS: 0 80 170 4 2 4 7 42 170 80 0 When you get to this point with a character of your own, you see how it looks. If you want to make any changes, move the dots as needed and rerun the program. If you want to put dots in the bottom row, change the number in line 190 from 128 to 0.
90 FOR P=58 TO 63: LPRINT CHR$(P);" ";: NEXT P 95 LPRINT 100 K=1: IF K>3 THEN A=58 ELSE A=60 110 LPRINT CHR$(27) :""CHR$(0)CHR$(0)CHR$(0); 120 LPRINT CHR$(27)"%"CHR$(l)CHR$(0); 130 LPRINT CHR$(27)"&"CHR$(0)CHR$(A)CHR$(A-1+K); 140 FOR Z=l TO K 150 LPRINT CHR$(128); 160 FOR X=1 TO 9 170 READ R 180 LPRINT CHR$(R);: NEXT X 190 LPRINT CHR$(0)CHR$(0); 200 NEXT Z 210 DATA 0,80,170,0,47,0,170,80,0 290 FOR P=58 TO 63: LPRINT CHR$(P);" ";: NEXT P To use this program for your own character or characters, change the DA
Running the program When you run this second program, it prints six characters, then redefines some or all of them and prints them again, as in the example below. When printed by your own program, these two lines provide you with a key to the characters your FX can now print. When you press the key for one of the characters in the top row, the printer prints the corresponding character in the bottom row.

Cleaning the Printer To keep your printer operating at its best, you should clean it thoroughly several times a year. Follow these steps to clean the printer: 1. Turn off the printer. 2. Remove the paper guide, tractor unit, and any installed options. 3. Use a soft brush to carefully clear away all dust and dirt. 4. If the outer case or paper guide is dirty or dusty, clean it with a soft, clean cloth dampened with mild detergent dissolved in water.
WARNING: l l l l Never use alcohols or thinners to clean the printer; these chemicals can damage the components as well as the case. Be careful not to get water on the printer mechanism or electronic components. Do not use a hard or abrasive brush. Do not spray the inside of the printer with lubricants; unsuitable oils can damage the mechanism. Contact your Epson dealer if you think lubrication is needed. Replacing the Ribbon When your printing becomes too faint you need to replace the ribbon.
2. Remove the old ribbon cartridge by grasping the black fin-like handles (two on the FX-1050, and one on the FX-850) and lifting the cartridge straight up and out of the printer. 3. 5-4 Slide the print head to the middle of the printer.
4. Unwrap the new ribbon, and turn the ribbon-tightening knob in the direction of the arrow to remove excess slack. 5. Hold the new ribbon cartridge by the fin-like handle(s), and firmly insert it into place, making sure that the plastic hooks fit into the slots as shown below.
6. Use a pointed object, such as the tip of a pencil, to guide the ribbon between the print head and ribbon guide. At the same time, turn the ribbon-tightening knob in the direction of the arrow to help guide the ribbon into place. 7. Check to make sure that the ribbon is not twisted or creased. You can check the installation by sliding the print head from side to side along the carriage. 8. Reattach the printer cover.
4. Remove the ribbon cartridge and platen knob. 5. Slide the print head to the middle of the printer. Then, using a cross-head screw driver, reattach the two red screws.
6. Attach the left and right locking tabs. 7. Slide the head all the way to the left, and insert the print head protector as shown below. 8. Attach the printer cover. After replacing the packing material, put the printer in its box and prepare it for transportation.

Troubleshooting This chapter discusses problems you may encounter and their likely solutions. At the back of the chapter is a section on the data dump mode. This mode helps more experienced users determine the causes of communication problems between the printer and the computer. Problems and Solutions This section lists possible problems and their likely solutions, The printer does not print l l l l Be sure the printer is turned on and the POWER light is on.
l If the printer stops and the beeper sounds, turn the printer off and then turn it back on and try to print again. If the printer beeps again and does not print, take it to a qualified service person. The printout is spaced incorrectly l l l If all the text is printed on the same line, no line feed command is being sent at the end of each line of text. Turn DIP switch 2-4 on. If the printer is inserting extra blank lines between lines of text, extra line feed commands are being sent.
If you cannot define user-defined characters, make sure that DIP switch 1-1 is off. Your software’s font, size, or page layout settings may not be selected properly. See that your software is correctly set up for your printer. Your application program may be changing the SelecType settings. Use the program’s setup procedure to remove codes that interfere with SelecType, or use the printer control codes for your application program instead of SelecType. (See your software manual.
Cut sheet feeder does not load paper correctly l The cut sheet feeder mode may not have been selected with the DIP switch. The position of the paper release lever may be wrong. Push the paper release lever back to the single sheet position. l l The cut sheet feeder may not be installed properly. l The paper supply may not be loaded properly. The paper may not be the type required for proper operation of the cut sheet feeder. l l The paper set lever of the cut sheet feeder may not be pushed back.
3. To turn off the data dump mode, press the ON LINE button to take the printer off line, and then turn off the printer. (The data dump mode can also be cancelled by sending an INIT signal from the computer.) Look at the data dump shown in Step 2. By comparing the characters printed in the right column with the printout of the hexadecimal codes, you can check what codes are being sent to the printer. If characters are printable, they appear as their true ASCII characters.

The Cut Sheet Feeder The optional cut sheet feeder gives you easier and more efficient handling of single sheet paper. Up to 150 sheets of standard bond paper can be fed automatically into the printer without reloading. The cut sheet feeder can also automatically feed envelopes. Printer FX-850 FX-1050 Single-bin Dual-bin #7339 #7346 #7340 #7348 Installation Attach the assembled cut sheet feeder as follows. 1. Turn off the printer. 2. Remove the printer cover and the paper guide. 3.
4. Remove the paper tension unit by pressing open the release levers and, at the same time, lifting up on the front of the unit. 5. Tilt the feeder forward slightly to fit the notches at the base of the unit over the pins on the printer: then tilt the unit back until it rests on top of the printer.
6. Detach the front section of the printer cover. 7. After raising the cut sheet feeder’s paper path guide, attach the front cover to the printer. Then close the paper path guide. Setting the sheet feeder mode To allow your printer to use the cut sheet feeder you need to set DIP switch 2-2 to on. If you need more information on how to do this, see the section on setting DIP switches in Chapter 3. To set the cut sheet feeder mode, do the following: Turn the printer off.
Recommended paper Paper: For best results, use typewriter-quality paper. If you use paper with a glossy or textured surface, you should test it before regular use. The cut sheet feeder can hold up to 150 sheets of paper. Do not use multiple-part forms or labels. Envelopes: You can print on air mail, plain, or bond envelopes. The cut sheet feeder can hold up to 25 plain or bond envelopes, or 30 air mail envelopes. Before printing on envelopes, you need to set the paper thickness lever.
2. Slide the left paper guide all the way to the left and slide the right paper guide to roughly match the width of your paper. 3. Take a stack of paper and fan it as shown. This keeps the sheets from sticking to one another. Tap the side and bottom of the paper on a flat surface to even up the stack.
4. Insert the paper between the paper guides, aligning it with the left edge of the guide. Then adjust the right paper guide until the paper is held firmly (but not so tightly that it causes the paper to bunch). 5. Push the paper set lever back to clamp the paper against the guide rollers. The lever will not close completely if you use too much paper. If the lever does not close, remove some paper from the stack and try again.
Envelope loading Envelopes are loaded in much the same way as regular paper. To load envelopes, you need to do the following: 1. Set the paper thickness lever to match the thickness of your envelopes. (For specific information on paper thickness settings, see the section on printing with special paper in Chapter 2.) 2. Follow steps 1 through 5 of the previous section on paper loading to load envelopes. You can load up to 25 plain or bond envelopes, or 30 air mail envelopes. 3.
and then press the ON LINE button. The printer starts printing from the point at which it was stopped. If you turn your printer off during the time the printer detects a paper out or paper jam condition, any data remaining in the printer’s buffer is discarded.
In addition to the number of printable lines, which your software may refer to as page length or form length, you may need to set the top margin, the bottom margin, and the actual number of lines to be printed on the page. The cut sheet feeder normally creates a two-line unprintable top margin. Therefore, if you want a total top margin of six lines (one inch), set the top margin in your software to four lines.
Many word processors and other software programs give you two ways to change these settings: l l You can change the settings in each individual file you print. You can change the program’s default settings so that every time you use the program, these new settings are in effect. If your program has additional features, such as headers and footers, you have to compensate accordingly. Control panel operation All of the functions from the control panel are available in cut sheet feeder mode.
Below is a portion of the first page of a self test in cut sheet feeder mode. The remainder of the self test is similar to the original self test described in Chapter 1. WARNING: Never perform the self test on envelopes. Switching from the cut sheet feeder to continuous paper The FX allows you to switch between cut sheet feeder paper and continuous paper easily without having to remove either the feeder or the continuous paper supply.
3. To switch from cut sheet feeder operation to continuous paper, pull the paper release lever all the way forward to the continuous paper position. You do not need to change the DIP switch setting. 4. Raise the paper path guide on the cut sheet feeder until it clicks open, as shown below. This guide directs the flow of continuous paper out of the front of the printer. 5. With the paper release lever foward, the control panel functions normally.
Single sheet insertion Your cut sheet feeder also has a single sheet loading feature. This feature allows you to switch to a different type of paper (such as letterhead) without replacing the supply of paper that is loaded in your cut sheet feeder. Single sheet insertion is especially useful because it allows you to use micro-adjustment to change your cut sheet feeder loading position. 1. Press the ON LINE button to take the printer off line. 2.
The Pull Tractor The optional pull tractor (#7311 for the FX-850 and #7312 for the FX-1050) provides optimum continuous paper handling. The pull tractor is especially useful with continuous multi-part forms and labels. For best results, use the pull tractor along with the built-in push tractor, as described in this section. After making sure that you have both parts of the pull tractor option as shown below, remove the packing material and save it in case you need to ship the unit later.
2. Remove the paper tension unit by pressing open the release levers and lifting up the front of the unit at the same time. 3. Hold the pull tractor with the gears to the right and fit the rear notches on the tractor over the rear mounting pins on the printer as shown below.
4. Tilt the tractor unit toward you until the front latches click in place over the front mounting pins of the printer. 5. Now load paper as described in the section on loading continuous paper in Chapter 2. However, position the left sprocket unit about 1/4 of an inch from the left before locking it in place. 6. After the paper is loaded in the push tractor, make sure the printer is off line and then press the FORM FEED button.
8. Move the sprocket units to match the width of the paper and adjust the paper supports so they are evenly placed between the sprocket units. (There is only one paper support on the IX-850 pull tractor.) 9. Fit the holes of the paper over the tractor pins of the sprocket units, adjusting the position of the sprocket units as necessary.
10. If the paper does not fit exactly onto the tractor pins, press in on the pull tractor feed knob and turn it in the desired direction. 11. Close the sprocket covers. 12. Make sure that the paper is not crooked or wrinkled and then lock the sprocket units in place.
13. Slide the rollers on the paper bail so they are evenly distributed across the width of your paper. Also, make sure that the right and left rollers are at both edges of your paper. 14. Re-install the paper guide and then slide the edge guides together so they meet at about the middle of the paper’s width. 15. Install the pull tractor cover.
16. Press the ON LINE button to put the printer on line. Now you are ready to begin printing. When you are finished printing The short tear-off function cannot be used with the pull tractor. If you want to tear off the last printed page at its perforation, press the ON LINE button to take the printer off line and press the FORM FEED button to feed the paper forward an additional page before tearing off the paper.
2. Replace the paper tension unit as shown below. 3. Now you are ready to use either single sheets or the push tractor. Interface Boards There are a number of optional interfaces that can be used to supplement the capabilities of your. printer’s built-in parallel interface.
l Serial interfaces are necessary if your computer is not equipped with a parallel interface. In addition, all available serial interface boards provide user-selectable baud rates and data word structures. These interfaces also offer some combination of the following features: X-on/X-off data communication protocol, and loopback self-test modes. If you are still unsure whether you need an optional interface, or would like to know more about interfaces, contact your Epson dealer.
WARNING: Hi voltage is present inside the printer when the power is on. Do not attempt to remove the upper case unless the printer is turned off and the power cord ,is unplugged. Also, do not touch contacts on the printer’s circuit board because many of the components can be destroyed by static electricity built up in your body. 2. Remove the printer cover, paper guide, ribbon cartridge, and any installed options. 3.
5. Reach inside the front cover and push in on the upper case fastening clips. These clips are located on both sides of the printer case. Push both clips at the same time as shown in the figure below. 6. Raise the upper case slightly (about six inches), taking care not to strain the flat cable attached to the control panel.
7. Carefully disconnect the control panel cable from the connector labelled CN11 on the main board. 8. Tilt the upper case backward and lift it clear of the printer body. Caution: Be very careful when removing or attaching the upper case to avoid damaging the printer.
9. Remove the option interface shield plate by pressing in on the plastic clips located at the back of the plate. 10. Remove the screw labelled CG from the main board.
Installing the board There are two basic interface board designs. These boards differ with respect to how the frame ground (FG) wire is attached. This slight difference changes the way the boards are installed in the printer, but does not affect the operation of the interface in any way. Look at the following illustration to see which type of interface board you have and then follow the installation procedure for that type of board.
2. Carefully insert the pins on the optional interface board into the mating connector on the main board. Secure the board with the three screws provided. 3. Attach the plug end of the FG wire onto the FG pin located on top of the interface board. 4. Set the DIP switches on the interface board according to the manual that comes with the board.
FG wire attached 1. Carefully place the interface board next to the printer as shown below. Use the CG screw to connect the round end of the FG (frame ground) wire to the main board. 2. Holding the interface board level, rotate it clockwise into position and attach it to the main board. Make sure that the connector pins are properly inserted into the mating connector.
3. Secure the board with the three screws provided. 4. Set the DIP switches on the interface board according to the manual that comes with the board. Attaching the upper case 1. Fit the hinges of the upper case into the openings in the lower case. Then partially lower the upper case.
Caution: Take care not to pinch the FG wire between the upper and lower cases. 2. Carefully insert the control panel cable into the connector labelled CN11 on the main board. 3. Close the upper case. Make sure you press down on the front of the case until it locks into place.
4. Insert and tighten the screw to secure the upper case, and then reattach the platen knob. WARNING: When installing an optional interface board, be sure to disconnect the printer cable from the printer’s built-in parallel interface. Two interface cables must not be installed at the same time. This completes the installation of the optional interface board. Replace the ribbon cartridge, printer cover, and any other necessary parts or options.
Chapter 8 Command Summary This chapter lists and describes all the commands, both Epson (ESC/P) mode and IBM emulation mode, available on the FX. The first part of this appendix lists all commands in numerical order and gives the page number where each is fully described. If you know which command you are looking for, consult the numerical list to find the page number where it is described.
The simplest type of command consists of a single character to be sent to the printer. For instance, to print in condensed mode the code format is: ASCII code: SI Decimal : 15 Hexadecimal: OF This code can be sent from a program by sending the code 15 directly. More complex commands consist of two or more character codes.
Control key chart Some application programs can use control key codes for decimal values 0 through 2 7. The table below gives you the proper values. The Control Key column indicates that you press the control key at the same time you press the key for the letter or symbol in that column. For example, you press the control key and A at the same time to send the value 1. Note: Many programs use the control keys for other purposes. Also, some programs do not use all these keys. Dec.
Commands in Numerical Order This section lists all the FX commands, with their decimal and hexadecimal values. The numbers in the columns on the right are the page numbers in this chapter where a complete description of the command can be found. If the Epson and IBM emulation mode page numbers are the same, the command is the same in both modes and is described only in the Epson mode section.

l l l l The column heading “Direction” refers to the direction of signal flow as viewed from the printer. “Return” denotes the twisted-pair return, to be connected at signal ground level. For the interface wiring, be sure to use a twisted-pair cable for each signal and to complete the connection on the return side. These cables should be shielded and connected to the chassis of the host computer and the printer. All interface conditions are based on TTL level.
Interface timing The figure below shows the timing for the parallel interface. Initialization There are three ways that the printer can be initialized (returned to a fixed set of conditions). Hardware initialization l l Software initialization A-8 l When the power is turned on. When the printer receives an INIT signal at the parallel interface (pin 31 goes LOW). Software sends the ESC @ (initialize the printer) command.

Epson Extended Graphics Character Table Tables B-7
Glossary Note that these definitions apply specifically to printers. If a word is italicized, see that topic for more information. application program A program that helps you carry out a particular task, such as word processing or financial planning. ASCII American Standard Code for Information Interchange. A standardized coding system for assigning numerical codes to letters and symbols.
carriage return The control code that returns the print position to the left margin. When issued together with a line feed, the print position moves to the left margin of the next line. In bidirectional printing, the print head may not actually move to the left margin. characters per inch (cpi) A measure of the size of text characters, often referred to as pitch. 10 cpi (also called pica) is often the standard or default setting.
default A value or setting that takes effect when the equipment is turned on, reset, or initialized. DIP switches Small switches in a printer that control various printer functions and set the default status of the printer when it is turned on or initialized. DIP stands for Dual In-line Package. dot graphics A graphic design formed by patterns of dots. dot matrix A method of printing in which each letter or symbol is formed by a pattern (matrix) of individual dots.
ESC (escape) A special control code used to begin most printer commands. ESC/P Abbreviation for Epson Standard Code for Printers. The system of commands lets you control your printer using your computer’s software. It is standard for all Epson printers and supported by most applications software for personal computers. font A style of type designated by a family name. form In printer terminology, a form is normally the equivalent of a page.
memory The printer, like a computer, has a memory. When you print a file from a computer, the contents of the file are transferred quickly from the computer’s memory to the printer’s memory. The printer then prints information from its own memory at a much slower rate. This way of printing frees the computer to do other work while the printer is still working. The printer memory is sometimes called the buffer. micro-adjustment A feature that adjusts the paper loading and tear-off positions.
parity Parity is a method for a computer and printer to check the reliability of data transmission. pitch Indicates the number of characters per inch (cpi). The standard is 10 pitch. platen The black roller that provides a backing for the printing. print quality Your printer has two types of print quality: draft and near letter quality (NLQ). Draft is for high-speed, draft-quality jobs; NLQ is for final, polished documents.
top of form position The position on the paper that the printer recognizes as the first printable line. For single sheets, this is the position to which the paper is automatically loaded. For continuous paper, this position can set to the current paper position by turning the printer off and on. user-defined characters Characters that are defined and stored in the printer by the user. Also known as download characters.
