Unpacking the Printer Checking the parts make sure you have all the parts AS you unpack the printer, shown below and that none have been damaged during transportation. In some locations the power cable is a separate item.
Unpacking the Printer Removing the protective materials The printer is protected during shipping by two brackets, two locking tabs, and a print head protector. These protective items must be removed before you turn on the printer. After removing these items, store them with the other packaging material in case you ever need to transport your printer. To remove the packing materials, follow these steps: 1.
Unpacking the Printer 2. Remove the print head protector. 3 Slide the print head to the middle of the printer. Then, remove the left and right locking tabs. Be sure to remove all protective materials before you turn on the printer.
Choosing a Place for the Printer There are several considerations in selecting a location for your printer. Be sure to keep the following in mind: Place the printer close enough to the computer for its cable to reach. Place the printer on a flat, stable surface. Leave room for easy printer operation and maintenance. Avoid locations that are subject to direct sunlight, excessive heat, moisture, or dust. Use a grounded outlet; do not use an adapter plug.
Assembling the Printer Installing the platen knob After you’ve decided on a location for your printer, the first step in setting it up is to install the platen knob. You will find the knob packed in an indentation in the white foam packing material. 1. Insert the knob into the hole on the right side of the printer. Rotate the knob until it slips onto the shaft. 2. Push firmly on the knob until it fits against the printer case.
Assembling the Printer Installing the ribbon To install the ribbon cartridge, follow these steps: 1. Make sure that the printer is not connected to an electrical outlet. 2. Remove the printer cover. 3. Slide the print head to the middle of the printer. 4. Turn the ribbon-tightening knob in the direction of the arrow to tighten the ribbon. This step removes excess slack in the ribbon and makes it easier to install.
Assembling the Printer 5. Hold the ribbon cartridge by its black, fin-like handles with the exposed ribbon away from you. (The LQ-850 ribbon cartridge has only one handle.) Push the cartridge firmly into position, making sure that the black plastic hooks fit into the slots inside the printer. 6. Use a pointed object, such as the tip of a pencil, to guide the ribbon between the print head and the ribbon guide.
Assembling the Printer Attaching the paper guide To install the paper guide, follow the steps listed below: 1. Place the paper guide on the printer as shown, making sure that the back edge of the guide is even with the back of the printer. 2. Raise the paper guide up until it locks in place. To lower the paper guide, lift up slightly to release it from its locked position and gently lower it down onto the printer.
Assembling the Printer 3. Attach the printer cover. 4. Close the paper guide 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. You should perform this test to make sure the printer was not damaged during shipping and to ensure that the ribbon has been installed correctly. Before carrying out the test, you need to load a sheet of paper into the printer.
Testing the Printer 2. Turn on the printer. The green POWER light and the red PAPER OUT light come on. After turning the printer off, always wait at least five seconds before turning it back on. Rapid switching of the power on and off can damage the printer. 3. Push the paper release lever back to the single sheet position.
Testing the Printer 4. Move the right and left edge guides of the paper guide to match the width of the platen (black roller), and insert a sheet of paper the same width. Never perform the self test on envelopes. 8 5. Push the LOAD/EJECT button to load the paper. If the platen turns without loading the paper, remove the paper and try the procedure once more, but press the paper a bit more firmly into place.
Testing the Printer Running the self test You are now ready to start the printer’s self test. This prints out the settings of the printer’s DIP switches and the characters in the printer’s memory. The DIP switch settings are explained later in this guide. This test can be performed in either of the LQ’s two printing modes: draft or LQ (Letter Quality). No matter which printing mode you run the test in, the DIP switch settings are always printed in draft.
Testing the Printer 3. The self test does not stop until the printer runs out of paper or you press the ON LINE button. After checking to see that everything is operating correctly, press the ON LINE button to stop the test. Part of a typical draft self test is shown below: on on 0f.f on off off off on on Serial odd ./0123456789:;<=>? ./0123456789:;<=>?@ ./0123456789:;<=>?@A HIJKLMNOPQR IJKLMNOPQRS JKLMNOPQRST /0123456789: ;<=>?OABCDEFGHIJKLMNOPQRSTUVW 4.
Testing the Printer 5. To perform this test in the LQ (letter quality) mode, load another sheet of paper. 6. Turn off the printer, then turn it on again while holding down the FORM FEED button. You need only hold the button down until printing begins. As before, the self test ends when the printer runs out of paper or when you press the ON LINE button. Part of a typical LQ self test is shown below: Count t-y us+l France Germany U.K.
Connecting the Printer to Your Computer Your LQ printer has two separate interface connections: a ® Centronics compatible parallel interface and an RS-232C compatible serial interface. If you are not sure which one is required by your computer, check your computer manual for this information. If you have a suitable shielded cable, you should be able to connect to most computers immediately. The printer is set up for parallel data communication at the factory.
Connecting the Printer to Your Computer The parallel interface When connecting your computer to the parallel interface, follow these steps: 1. Make sure both the printer and your computer are turned off. 2. Plug the cable connector into the printer as shown below. Next squeeze the wire clips together until they lock onto either side of the connector. If your cable has a ground wire, attach this wire to the ground connector of the printer. 3. Plug the other end of the interface cable into the computer.
Connecting the Printer to Your Computer The serial interface If you are going to use a serial interface, it is best to choose an Epson serial interface cable. The following is a list of interface cables and the computers they are designed to work with: Computer ® Apple IIc ® IBM PC and compatibles Most other computers Epson cable #8239 #8297 #8293 When connecting your computer to the serial interface, follow these steps: 1. Make sure both the printer and your computer are turned off. 2.

Using Single Sheets Your printer can handle a wide range of paper sizes up to a maximum width of 10.1 inches on the LQ-850, 13.0 inches on the LQ-950, or 14.4 inches on the LQ-1050. Always make sure that your printing is confined to the size of paper you are using. Avoid printing on the platen (black roller) at all times. If you do most of your printing on single sheets, you may find it more convenient to install the optional cut sheet feeder.
Using Single Sheets 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.
Using Single Sheets 6. Press the LOAD/EJECT button to automatically feed the paper to the loading position. Never advance the paper using the platen knob while the printer is turned on. 7. Press the ON LINE button so that the ON LINE indicator lights up. When the printer is on line it can accept data from your computer. If the platen (black roller) turns but the sheet does not load, remove the sheet from the printer and try again.
Using Single Sheets Reloading during printing When you print a document more than one page long using single-sheet paper, there are two ways your software can *allow you to load a new sheet at the end of a printed page: l If your software sends characters in a continuous stream, the printer stops printing when it reaches the bottom of the paper. When this happens, the page ejects and the ON LINE light goes off automatically.
Using Continuous Paper The tractor built into the LQ is remarkably easy to load and operate. Its low-profile design takes up little space and can handle a wide variety of paper widths. To load continuous paper, follow these steps: 1. See that the printer is turned off. 2. Pull the paper release lever forward to the continuous paper position. 3. Open the paper guide cover and remove the paper guide.
Using Continuous Paper 4. Attach the paper rest. 5. Release the sprocket lock levers and slide the left sprocket unit all the way to the left and lock it in place. Next, slide the right sprocket unit to roughly match the width of your paper.
Using Continuous Paper 6. Slide the paper support to a point midway between the sprocket units. 7. Open the sprocket covers.
Using Continuous Paper 8. Fit the first four holes in the paper over the pins of each sprocket unit making sure the paper is under the silver edge ; then close the sprocket covers. Slide the right sprocket unit to a position where the paper is straight and has no wrinkles; then lock it in place. Make sure the first sheet of paper has clean, straight edge and feeds under the silver edge to in sure correct paper feeding.
Using Continuous Paper 9. Reattach the paper guide as shown below; then slide the edge guides together so that they meet at about the middle of the paper’s width. When using continuous paper, always make sure that the edge guides are pushed together. 10. Close the paper guide cover and turn on the printer. 11. 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. 12.
Using Continuous Paper When using continuous paper, you can also choose the short tear-off feature to give you added paper-handling capabilities. When this feature is selected, the printer automatically feeds the paper forward so that you can tear it off at its perforation. Then, it feeds the paper backward when data is received so you can resume printing at the loading position. This feature makes it easier to detach printed pages and saves the blank pages that are usually lost between printing jobs.
f33Etiing Between Continuous and Single 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 paper guide cover and press the ON LINE button to set the printer off line. Then, remove your printed document.
Switching Between Continuous and Single Sheets 2. 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 no longer in the paper path. The PAPER OUT light comes on when the paper is completely out of the paper path. A 1 . Pressing the LOAD/EJECT button once may not feed the paper back enough to reach a standby position.
Switching Between Continuous and Single Sheets 4. Stand the paper guide upright, and adjust the edge guides to roughly match the width of your paper. 5. Close the paper guide cover. Next, insert the paper between the edge guides. 6. Press the LOAD/EJECT button to automatically feed the page to the loading position. 7. Press the ON LINE button to set the printer on line so that it is ready to print.
Switching Between Continuous and Single Sheets Switching back to continuous paper To switch back to printing with continuous paper, first see that the single sheet has ejected. 1. Open the sheet guide cover. Next, lower the paper guide onto the back of the printer and slide the edge guides together so that they meet at about the middle of the paper’s width. 2. Pull the paper release lever toward you. 3. Press the LOAD/EJECT button to feed the paper to the loading position. 4.
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 manually or with the optional cut sheet feeder. Before printing on these special types of paper you need to adjust the paper thickness setting. Never use reverse feed with labels.
Printing on Special Paper For printing on special types of paper, see the table below. When the paper thickness lever is set to position 4 or higher, the MULTIPART light comes on and the printing speed is reduced. The following table 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 2-sheet 3-sheet 4-sheet Labels Envelopes Air mail Plain Bond (20 lb.) Bond (24 lb.
Printing on Special Paper When you print on anything thicker than normal paper, such as envelopes or multi-part forms, be absolutely sure that your printing stays within the printable area of the paper. See pages 2-20 and 8-3 for more about printable area. Multi-part forms Your printer can also use continuous multi-part forms. These multiple forms should have no more than four parts including the original. Multi-part forms should not be used with the single-sheet feeding system or the cut sheet feeder.
Printing on Special Paper Never feed the labels backward through the printer. Labels can easily come off the backing and jam the 8 printer. Also, never use the LOAD/EJECT button to eject labels or to feed labels backward to the standby position. If a label does become stuck in the printer mechanism, refer the problem to your dealer. Since labels are especially sensitive to temperature and humidity, always use them under normal operating conditions.
Printing on Special Paper 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. 0.33 n or more 3- J k0.12” or more i - 0.87” or more t To make sure that the printing fits within this area, always perform a sample printing test using a normal single sheet of paper before printing on envelopes.

The orange indicator lights show which font has been selected. If optional font modules have been installed, these fonts can be selected by choosing either SLOT A or SLOT B.
Operating the Control Panel Other control panel features The control panel of the LQ also gives you access to several special functions. Self test By holding down the FORM FEED or LINE FEED button while you turn on the printer, you can start the LQ’s self test. This prints out the DIP switch settings and the characters in the printer’s ROM (Read Only Memory). See the section on the self test in Chapter 1 for further information.
Setting the DIP Switches By adjusting the settings of the two groups of DIP switches (SW1 and SW2) in the back of the printer, you can control various features such as character set and page length. To change the setting of a DIP switch, first turn off the printer. Using a pencil, pen, or other pointed instrument, change the setting as shown below. Then, turn the printer back on. Your new settings will not become effective unless the printer is turned off and on, or reset.
Setting DIP Switches the The tables below describe the functions of the DIP switches. DIP Switch 1 Switch Description OFF ON 1-1 1-2 International character set See the table below. 1-3 I 1-4 Character table 1-5 Print direction for graphics 1-6 1 Not used Graphics Italics Unidir. Bidir.

Interface/parity selection Baud rate selection pgyz$=j Print direction for graphics With unidirectional printing, the print head prints in one direction only to eliminate any possible deviation in the dot positions, making it ideal for printing graphics such as lines or boxes.
Page Length By setting DIP switch 2-1, you can select a page length of 11 or 12 inches. By turning the switch on, you set the page length at 12 inches. When you turn the switch off, you set the page length at 11 inches. To change the setting of a DIP switch, first turn off the printer. Next, change the DIP switch; then turn the printer back on.
Skip Over Perforation When skip over perforation 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. This feature may be useful when using continuous paper because it will cause the printer to stop printing, skip over the perforation, then resume printing. If you adjust your loading position correctly, you can get half of the margin at the bottom of one page and half at the top of the next page, as shown below.
Skip Over Perforation Most application programs take care of the top and 1 bottom margins. Therefore, do not turn skip over A perforation on unless your program does not provide these l margins.
Adjusting the Loading Position The loading position The loading position is the position of the paper when it has been automatically loaded by the printer. The loading 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, change the loading position using the micro-adjustment feature described below. Never use the platen knob for paper feeding except in case of a paper jam or other paper feeding problem.
Adjusting the Loading Position To perform micro adjustment of the loading position, first load your paper, and then press the ON LINE button to set the printer on line. The MULTI-PART indicator light starts to flash. While this light is flashing, you can use the FORM FEED and LINE FEED buttons for micro adjustments. Now press the FORM FEED button to feed the paper forward or the LINE FEED button to feed the paper backward. Each time you press the button, the paper moves 1/180 of an inch.
Short Tear Off When you are finished printing, the short tear-off feature automatically feeds the perforation of the continuous paper to the tear-off edge of the sheet guide cover so that you can tear off the last sheet. When you resume printing, the paper feeds back to the loading position. To use this feature, first turn off the printer and turn DIP switch 2-7 on. Then, load continuous paper in the normal way, but leave the paper guide cover open so that you can use the guide’s tear-off edge.
Short Tear Off 3. If you need to adjust the position of the perforation to meet the tear-off edge, use micro adjustment. First, see that the printer is on line and the MULTI-PART indicator light is flashing. Then, adjust the position in 1/180 of an inch increments by pressing the FORM FEED button to feed the paper forward or the LINE FEED button to feed it backward. Use micro adjustment to adjust the tear-off position immediately after the operation of the short tear-off function.
Selecting Typestyles Your printer can produce a wide range of typestyles by combining different fonts, pitches, widths, and other enhancements. You can select the typestyles in two different ways: by using software commands, and by pressing SelecType buttons on the control panel. 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 setting.
Selecting Typestyles Draft mode uses fewer dots per character for high-speed printing. DRAFT We’ve just seen your excellent a d for zebras in a recent back issue of T..ca.d.s..r . ..~...s T.i..me.s - W h a t i s t h e p r i c e s c h e d u l e for quantities over one g r o s s ? miniature The Roman and Sans Serif Letter Quality (LQ) fonts use a larger number of dots for higher print quality at a lower speed. ROMAN . '"#$%&'()*+,-.
Selecting Typestyles Character pitch For each of the three built-in fonts, you can choose a character pitch of 10, 12, or 15 characters per inch (CPI), and for all except draft you can choose proportional spacing (PS). To select a pitch, press the PITCH button until the indicator light of the desired pitch comes on. Note that some font modules do not offer all pitches. See the section on font modules in Chapter 7. The following printout compares the three pitches: This is 10 CPI printing.
Selecting Typestyles Condensed mode In addition to the three pitches and proportional spacing, you can also use the condensed mode to change the character size. In condensed mode, characters are approximately 60% of the width of normal characters; so it is very useful for spreadsheets and other applications where you need to print the maximum amount of information on a page. Both 10 and 12 CPI and proportional can be condensed; 15 CPI cannot.
Selecting Character Sets By changing the setting of the DIP switches, you can select one of eight international character sets and one of two character tables. Once you have set the DIP switches for a certain character set, that set is the default character set; it remains valid even after the printer is turned off, reset, or intialized. Software commands however, override DIP switch settings until they are cancelled or the printer is turned off, reset, or intialized.
setting ChalWAer sets Choosing a character table DIP switch l-4 selects the italics character table or the Epson Extended Graphics character table. The Epson Extended Graphics character table contains international accented characters, Greek characters, and character graphics for printing lines, corners, and shaded areas. Since the character table setting affects only the upper half of the character table, you can still print text if you have selected the Extended Graphics set.

Software Now that you have set up and tested the LQ, you should make sure that it works with the application programs you want to use. Most application programs let you specify the type of printer you are using so that the program can take full advantage of the printer’s features. Many of these programs provide an installation or setup section that presents a list of printers from which to choose.
Software A quick test After you set up your application program for your printer by following the instructions in the application program manual and the instructions above, print a sample document to make sure that the program and the printer are communicating properly. If the document does not print the way you think it should, re-check the program’s printer selection and installation routine. If you are still having trouble printing, consult Chapter 6.
Software Naming and using commands In order to use printer commands, you should know how they are recognized by your software program. The most common way of naming codes or commands is with one of two numbering systems, decimal or hexadecimal. The decimal system is the standard numbering system based on units of ten, using the numerals 0-9. The hexadecimal, or hex, system is based on units of 16, and is often used by programmers.
Software Once you have installed your word processor by using the lists on page 4-2, you can ordinarily use a fixed set of printer features by using a word processor command to place markers around the text to be altered. When the document is printed, the markers are recognized and translated into suitable commands for your printer. On your screen, some programs show the markers in a distinctive way, while others display the text as it will appear-for example, in bold or italics.
0 If you’re still having difficulty printing, check the troubleshooting section in your word processor’s manual and Chapter 6 of this manual. Spreadsheets Although spreadsheets seldom use as many printing styles as word processors, they do have some very specific requirements. Installation and column width If your spreadsheet program provides a list of printers, use the list on page 4-2 to find the proper selection.
Software The command for 12 cpi is ESC M, and the command for condensed is SI. Because most spreadsheets use the decimal equivalent for the commands, (also given in the Command Summary), a setup string for condensed 12 cpi might look like this: /027/077/015 The number 027 is for the escape code, 077 is for M, and 015 is for SI (condensed). The second method is SelecType, a feature described in Chapter 3. This feature allows you to choose print styles with buttons on the control panel.
Graphics The dot graphics mode allows your LQ 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 page and the next by simply giving your software a few instructions. The quickest and easiest way to print graphics on your LQ is to use a commercial graphics program.
Graphics I ncome Breakdown Marketing and Advertising \ Profit Salaries and Production - Development The print head To understand dot graphics you need to know a little about how the LQ’s print head works. The LQ’s print head has 24 pins. As it moves across the page, electrical impulses cause the pins to fire. Each time a pin fires, it strikes the inked ribbon and presses it against the paper to produce a small dot.
Graphics Dot patterns The LQ’s print head is able to print graphics as well as text because graphic images are formed on the LQ 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 LQ also forms its images with patterns of dots, as many as 360 dot positions per inch horizontally and 180 dots vertically.
Graphics Pin labels To tell the printer which pins to fire in each column, you first divide each of the vertical columns into three sections of eight pins each and consider each section separately. Since there are 256 possible combinations of the eight pins in each section, you need a numbering system that allows you to use a single number to specify which of the 256 possible patterns you want. This numbering system is shown below: 128 2 16 8 4 1 I To fire any one pin, you send its number.
Graphics Since there are 24 pins in each column, you must make a calculation for each of the three sections in each column. As you can see, this method of planning and printing dot graphics requires considerable calculation. Because triple-density uses 180 columns per inch, printing a single line of triple-density graphics only one inch long requires 540 numbers. Fortunately, commercial software can do the calculations for you.
Graphics *Adjacent dots cannot be printed in this mode. Column reservation numbers The graphics command requires more than one number to specify how many columns to reserve because one line can use thousands of columns, but the LQ does not use numbers larger than 255 (decimal). Therefore, the graphics mode command uses two numbers for reserving columns. To figure nl and n2, divide the total number of columns by 256. The result is n2; the remainder is nl.
For example, if you wish to send 1632 columns of graphics data, nl should be 96 and n2 should be 6 because 1632 = 96 + (6 x 256). The LQ will interpret the number of bytes determined by nl and n2 as graphics data, no matter what codes they are. This means that you must be sure to supply enough bytes of graphics data or the LQ will stop and wait for more data and will seem to be locked. If, on the other hand, you supply too much graphics data, the excess will be interpreted and printed as regular text.
The illustration below shows how you can use a grid to plan where you want dots to be printed. This grid is for a sin le line of graphics 42 columns long. Since each line of 24-pin grapa its is approximately 1/8th of an inch high and since triple-density graphics prints 180 dots per inch horizontally, a design planned on this figure will be about 1/8th of an inch high and less than 1/4th of an inch wide.
Graphics Below is shown the same grid divided into three sections to make the data calculation easier. At the the bottom of each section of each column is the total of the pin numbers for that section. This gives you a total of 126 data numbers necessary to print this small figure.
Graphics Here is the BASIC program that prints the design shown on the previous pages. Notice that the data numbers in lines 80-140 are the same numbers that you see in the last illustration. Also note that the WIDTH statement in line 10 is for IBM PC BASIC; the format may be different for your system.
Graphics Adding the following lines to the program above will cause the pattern to print 10 times in a row as shown below. 15 FOR C=l TO 10: RESTORE 65 NEXT C Individual graphics options commands As previously mentioned, the LQ responds to commands that are used by Epson FX and RX series printers. There are four individual graphics options commands that are very much the same as the ESC * command, but each one works for only one graphics option. All these commands are 8-pin graphics options.
Graphics The reassigning command The LQ has a command that allows you to change the graphics option assigned to any of the four individual graphics options commands. The command looks like this: ESC ? s m The letter s represents the command that you wish to change the assignment for (K, L, Y, or Z) and m is the number of the graphics option that you want to assign to it.
User-Defined Characters With the LQ, it is possible to define and print characters of your own design. You can design an entirely new alphabet or typeface, create characters for special applications such as mathematical or scientific symbols, or create graphic patterns with user-defined characters to serve as building blocks for larger designs. Below you can see samples of typefaces created with the userdefined character function.
User-Defined Characters Design grids To design a character you use a grid that is 24 dots high-one dot for each pin on the LQ print head. The width of the character matrix is dependent upon the character set in use. For draft characters, the grid is nine dots wide. For Letter Quality it is 29 dots wide, and for proportional characters it is 37 dots wide, with the dots for both Letter Quality and proportional spaced more closely together than those for draft.
User-Defined Characters Defining Your Own Characters The first step in defining characters is to place the dots on a grid just as you want them to print. The examples here, like the ones in the graphics section, use an x to represent each dot. In the illustration below you see a draft grid with a simple user-defined character planned on it. Now you translate the dot pattern you’ve created on paper to a numeric format so you can send the information to the LQ. Every dot has an assigned value.
User-Defined Characters The next illustration shows how to use this method to calculate the data numbers for the example character. On the left side of the figure the data numbers are calculated for the middle column. The value of each byte is calculated by adding the values of the rows where dots appear. The right side of the figure shows the whole character with the three data numbers for each column indicated at the bottom.
User-Defined Characters Sending information to the LQ The printer loads characters in the print style (Letter Quality, draft, or proportional) that the printer is currently using. It also records whether italic or script (either superscript or subscript) is turned on. This means that if you want to print a character in the italic mode, for example, you must have the italic mode turned on when you define the character. The LQ command to define characters is one of the most complex in its repertoire.
User-Defined Characters Following the specification of the range of characters to be defined in this command are three data bytes (do-d2) that specify the width of the character and the space around it. The left space (in dot columns) is specified by do, and the right space is specified by d2. The second byte (dl) specifies the number of columns of dots that are printed to make up the character.
User-Defined Characters An example character definition program should make this clear: 10 20 30 40 50 60 70 80 90 100 1x3 --,c-\jr “r,&&;” I..-A “---L-;l’“,\ w’--(g) ; l=F.I!Ji CL.,\r, , 10 ur-2..3 120 ‘-3SpJT 130 140 1551 160 2x2 3A"A +,0,0,2,0,0,4,0,0 3~21 8,0,0,23,255,2:0,8,0,0 DATA ~,0,0,2,0,0,1,0,0 “40660~’ irrrr In line 10, the ESC x command selects draft style printing. The actual character definition starts in line 20.
User-Defined Characters Printing user-defined characters If you entered the example program above, you defined an arrow and placed it in the RAM location for ASCII code 64 (replacing the at sign). You can now print out a three line sample of your work. The first and third lines (printed by lines 80 and 120 of the program) print the normal at sign; the second line (line 100) prints the arrow that you defined.
In many cases, you will want to redefine only a few of the characters to suit your needs; the rest of the alphabet will work fine as it is. As you have seen, it is possible to switch back and forth at will between the normal character set and the user-defined character set. It is, however, rather inconvenient. Therefore, the LQ has a command which allows you to copy all of the standard characters from ROM to the user-defined character set.
User-Defined Characters Superscripts and subscripts You can also create superscript and subscript user-defined characters. Just as Letter Quality characters are defined when the Letter Quality mode is selected, super/subscript characters are created when either superscript or subscript is selected. These super/subscript characters can be used either as superscripts or as subscripts. The characters are exactly the same; it is only their placement that differs.
User-Defined Characters Mixing print styles Each of the three user-defined character modes (draft, Letter Quality, and proportional) can be used in combination with most of the LQ’s various print styles. For instance, emphasized works with user-defined characters. The characters you design are enhanced to give this printing effect. Mixing the three types of user-defined characters is not permitted.
Replacing the Ribbon 5-2 Transporting the Printer 5-4 Cleaning the Printer 5-6
Replacing the Ribbon When your printing becomes too faint you need to replace the ribbon. Use the following Epson replacement ribbons: Printer LQ-850 LQ-950 LQ-1050 Standard ribbon Film ribbon #7753 #7767 #7754 #7768 #7769 #7770 To replace the ribbon, turn off the power to the printer and remove the printer cover. If the printer has been used recently, the print head may be hot. Let it cool before attempting to replace the ribbon. 1.
Replacing the Ribbon 3. Unwrap the new ribbon, and turn the ribbon-tightening knob in the direction of the arrow to remove excess slack. 4. Hold the new ribbon cartridge by its handles, and firmly insert it into position, making sure that the plastic hooks fit into the slots as shown below. (The LQ-850 ribbon cartridge has only one handle.) 5. Use a pointed object, such as the tip of a pencil, to guide the ribbon between the print head and the ribbon guide.
Transporting the printer If you need to transport your printer some distance, repack the printer using the original box and packing material. 1. Remove the printer cover, platen knob, paper guide, and any installed options. 2. Slide the print head to the middle of the printer. While holding the paper bail open, reattach the left and right locking tabs. Then, slide the print head all the way to the right, and insert the print head protector between the paper bail and platen as shown below. 3.
Transporting the Printer 4. Fit the printer back into the foam packaging material and then back into its original box. When you carry the printer, never hold it by the option compartment cover. This cover could come off and cause you to drop the printer.
Cleaning the Printer To keep your printer operating at its best, you should clean it thoroughly several times a year. To do this, unplug it from the power, remove any options that may be installed, as well as the ribbon cartridge. Carefully clean the printer using a soft brush and a vacuum cleaner with a small nozzle. Clear away all dust and dirt. Slide the print head to one side in order to clean beneath it. Be careful not to damage any of the parts inside the printer.
Troubleshooting Problems and solutions Data dump mode 6-2 6-2 6-5
Troubleshooting This chapter discusses problems you may encounter, and their likely solution. 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 application programs. Problems and solutions This section lists possible problems and likely solutions. The printer does not print l Make sure that the printer is turned on and the POWER light is on.
Troubleshooting The printer stops printing l The printer may be out of paper. Check the paper supply. l The paper may be jammed. See the section on the self test in Chapter 1. l The ribbon may be jammed. See the section on the self test in Chapter 1. l l If the READY light is off and the ON LINE light is flickering, the LQ has stopped to allow the print head to cool. Printing resumes soon; you do not have to do anything to re-start it.
Troubleshooting Continuous paper does not feed properly The position of the paper release lever may be wrong. Pull it forward to the continuous paper position. See that the sprocket holes of the paper fit correctly over the sprockets. The paper guide may not be installed properly. See the section on continuous paper in Chapter 2. The paper supply may be stacked too far from the printer, not aligned with tractor, or there may be some obstacle in the way of the paper.
Troubleshooting Cut sheet feeder does not load paper correctly l The cut sheet feeder mode has not been selected with the DIP switch. l The position of the paper release lever is wrong. Push the paper release lever back to the single sheet position. l The cut sheet feeder is not installed properly. l The paper supply is not loaded properly. l The paper set lever of the cut sheet feeder is not pushed back. l The page length is not set correctly.
Troubleshooting 3. To turn off the data dump mode, press the ON LINE button to stop the printing and set the printer off line, then turn off the printer. (It can also be cancelled by sending an INIT signal from the computer .) The data dump shown in Step 2 was made while writing this section. By comparing the characters printed in the right column with the printout of hex 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 feeders give 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. These units can also automatically feed envelopes. Printer LQ-850 LQ-950 LQ-1050 Single bin #7339 #7345 #7340 Dual bin #7346 #7347 #7348 The illustrations in this chapter show the single bin feeder for the LQ-1050, but the others work in the same way.
The Cut Sheet Feeder Assembly ends together 1. Attach the paper feeder rests by squeezing the free and inserting them into the slots as shown. 2. Insert the paper support over the back edge of the feeder.
The Cut Sheet Feeder 3. Attach the two front stacker supports as shown. (There is only one front paper support on the cut sheet feeder designed for the LQ-850 printer.) Installation Attach the assembled cut sheet feeder as follows. 1. Remove the printer cover and the paper guide. 2. Make sure the paper release lever is pushed all the way back.
The Cut Sheet Feeder 3. Remove the paper tension unit by pressing open the release levers and, at the same time, lifting up on the front of the unit. 4. 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 its rests on top of the printer.
The Cut Sheet Feeder 5. Detach the front section of the printer cover. 6. After raising the cut sheet feeder’s paper path guide, attach the front cover; then close the paper path guide.
The Cut Sheet Feeder Setting the sheet feeder mode To allow your printer to use the cut sheet feeder you will need to set DIP switch 1-7 to on. If you need more information on how to do this, see the section on DIP switch setting in Chapter 3. To set the printer into the cut sheet feeder mode, you should do the following: l l l Turn the printer off Set DIP switch 1-7 to the on position using a pointed object, such as the tip of a pencil. Turn the printer back on.
Paper loading To load paper, follow the steps below. 1. Pull the paper set lever all the way forward until the paper supports retract and lock open to allow for paper loading. Make sure that the two small front levers are up when using normal paper. 2. Slide the left paper guide so that the fin on the edge guide matches the arrow on the metal; then slide the right paper guide to roughly match the width of your paper.
The Cut Sheet Feeder 3. Take a stack of paper and fan it as shown. This keeps the paper from sticking so that only one sheet feeds at a time. 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.
The Cut Sheet Feeder 5. Push the paper set lever back until it clicks into place and clamps the paper against the guide rollers. The lever will not close completely if too much paper is used. If this happens, remove some paper from the stack and try again. Envelope Envelopes are loaded in much the same way as regular paper. T o load envelopes, you need to do the following: 1. Set the paper thickness lever to match the thickness of your envelopes. 2.
The Cut Sheet Feeder Using the cut sheet feeder After loading paper into the cut sheet feeder, make sure that the ON LINE light is on. Once the printer is in the sheet feeder mode, a new sheet of paper loads automatically whenever a printable character or line feeding command is sent to the printer. When the printer finds that it cannot load a sheet of paper because the paper bin is empty, it stops paper feeding and the PAPER OUT light comes on.
The Cut Sheet Feeder Setting up your software When you switch between continuous paper and cut sheet feeder fed paper you usually need to change the settings of your software program. Because of the physical requirements of feeding a single sheet of paper, sheet feeders always create an unprintable top and bottom margin on each sheet. To work properly, your software program needs to know how many printable lines are available on the page.
The Cut Sheet Feeder The following is a typical example of a software setup required for proper operation of your cut sheet feeder. Not all software is set up the same, so you may find that a bit of experimentation is required before you find the best equivalent settings to use.
The Cut Sheet Feeder Testing the printer in the cut sheet feeder mode When performing the printer’s built-in self test in the cut sheet feeder mode, the print out is slightly different from that of the original self test. Load the paper you will be using into the paper bin. Hold down the LINE FEED or FORM FEED button and turn the power switch on as described in Chapter 1.
The Cut Sheet Feeder 1. Make sure that the continuous paper is already loaded and in a standby position as explained in Chapter 2. 2. Install the cut sheet feeder as described in this section, making sure that DIP switch 1-7 is set to on, and that the paper release lever is pushed all the way back. 3. To switch from cut sheet feeder operation to continuous paper, pull the paper release lever all the way forward. You will not need to change the DIP switch setting.
The Pull Tractor The optional pull tractor (#7311 for the LQ-850, #7313 for the LQ-950, or #7312 for the LQ-1050) provides optimum continuous paper handling. The pull tractor is especially useful1 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.
The Pull Tractor Installation and use After making sure that the printer is turned off, install and use the pull tractor as follows: 1. Remove the printer cover and the paper guide and install the paper rest if you haven’t already. (See page 2-7.) 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.
The Pull Tractor 4. Then, tilt the tractor unit toward you until the front latches click in place over the front mounting pins of the printer. 5. Now load continuous paper as described on pages 2-6 to 2-10. However, in Step 5, 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, see that the printer is off line and press the FORM FEED button.
The Pull Tractor 8. Adjust the sprocket frames 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 LQ-850.) 9. Fit the holes of the paper over the tractor pins of the sprocket frames, adjusting the position of the sprocket units as necessary.
The Pull Tractor 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.
The Pull Tractor 12. See that the paper is not crooked or wrinkled and 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 the both edges of your paper.
The Pull Tractor 14. Re-install the paper guide; then slide the edge guides together so they meet at about the middle of the paper’s width. 15. Install the pull tractor cover as shown below. 16. Press the ON LINE button to set 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.
The Pull Tractor Removing the pull tractor After turning off the printer and removing the pull tractor cover, remove the pull tractor as follows: 1. Press the tabs on the pull tractor and tilt it back and lift it off the printer. 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 serial and parallel interfaces. If you are unsure whether you need an optional interface, or would like to know more about interfaces, check with your Epson dealer. Compatible interfaces The following is a list of Epson interfaces that are compatible with your LQ printer.
Interface Boards Installing the interface board This section describes how to install the optional interface boards available for use with your LQ printer. Installation is easy, and the only tool you need is a cross-head screwdriver. High voltages are present inside the printer when the power is on. Do not attempt to remove the cover unless the minter is turned off and the power cord is unplugged.
Interface Boards 4. Detach the upper case by pressing in on the two retaining clips inside the front of the printer. 5. Partially raise the upper case; then reach under and detach the control panel by releasing the front clip.
Interface Boards 6. Slip the control panel back through the upper case. With the control panel free of the upper case, tilt the case straight back to detach the rear hinges, and then lift it off. 7. Remove the shield plate at the back of the printer to allow access to the optional interface connector.
Interface Boards 8. Remove the power cable attached to the main board. To remove, grasp the clip at its base and pull gently, but firmly, straight up. You may need to move the clip back and forth slightly as you pull upward to free it from-the board. 9. Remove the screw labelled CG from the main board. This ground connector screw is located next to the power cable connector.
Interface Boards There are two basic interface designs. Each is installed slightly differently. Both installation procedures are described below. The difference in design does not affect the operation of the interface in any way. Pictured below are the two basic designs. Check to see which one you have. FG wire not attached FG wire attached FG wire not attached The following section describes installation procedures for an interface board without the FG (frame ground) wire attached.
Interface Boards 1. Using the CG screw, attach the round end of the FG (frame ground) wire to the main board. Position the other end of the wire as shown. 2. Reattach the power cable, making sure that the small fins on the white plastic clip are on the side away from you. Take extra care to see that the holes of the clip are aligned with the pins of the connector.
Interface Boards 3. Fit the interface board under the built-in tractor as shown in the illustration. Next, carefully insert the pins on the optional interface board into the mating connector on the main board. Secure the board with the screws provided. 4. Attach the plug end of the FG wire onto the FG pin located on top of the interface board. 5. Reassemble the printer, taking care not to pinch the FG wire between the upper and lower sections of the case.

The Command Summary This chapter lists and describes all the commands available on the LQ-850, LQ-950, and LQ-1050. This summary is divided by topics, but there is a list of the commands in numerical order beginning on page 9-4. If you know which command you are looking for, consult this list to find the page number where it is described.
All three formats are equivalent, so you can pick the one best suited to your purpose. For instance, a BASIC programmer might refer to the first and second formats, a word processor might use the second, and a machine code programmer would use the third format. Variables are represented by italicized letters such as n, nl, m. The variables are explained in the comments section. Some application programs make use of control key sequences. See the Control key chart on page 9-4 of this chapter.
More complex commands consist of two or more character codes. For example, to print in proportional mode the code format is: ASCII code: Decimal: Hexadecimal: ESC p 27 112 : 1B 70 n In this case n can be either 1 or 0, to begin or end proportional printing. To turn ON proportional printing from BASIC the command is: LPRINT CHR$(27);CHR$(112);CHR$(l) Control key chart Some application programs can use control key codes for decimal values O-27. The table below gives you the proper values.

Glossary Note that these definitions apply specifically to printers. If a word is italicized, see that topic for more information. Application program Software designed to perform a specific task, such as word processing or accounting. ASCII American Standard Code for Information Interchange. A standardized coding system for letters and symbols used by nearly all manufacturers of computers, printers, and software. Baud rate A measure of the speed of data transmission. Usually equivalent to bits per second.
Glossary Continuous paper This paper has pin-feed holes on each side and is perforated between pages. Also called fan-fold paper. Control code The ASCII standard includes codes for printable characters and 33 other codes, which are called control codes. These are the codes for such functions as sounding the beeper and performing a carriage return. Cut sheet feeder An optional device that automatically feeds single sheets of paper into the printer. Data dump A trouble-shooting feature.
Glossary Double width A print width in which each character is twice as wide as normal characters. Draft One of two print qualities available on the LQ. Draft uses a minimum number of dots per character for high-speed printing. See also Letter Quality. Escape (ESC) A special control code used to begin most printer commands. ESC/P Abbreviation for Epson Standard Code for Printers, a set of commands developed by Epson and supported by almost all application software for personal computers.
Glossary Hexadecimal (hex) See Number systems. Hex dump See Data dump. Initialize Return the printer to its defaults. Interface The connection between the computer and the printer. A serial interface transmits data one bit at a time and a parallel interface transmits data one character or code at a time. Italic A typestyle in which the characters slant. This sentence is italicized. Letter Quality (LQ) One of two methods of printing on the LQ.
Glossary Decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. (This is the most familiar system.) Hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. This is frequently used by programmers. Any decimal number between 0 and 255 can be expressed by a two-digit hex number. Binary is base 2 and uses only the digits 0 and 1. All information in computer systems is handled in binary form representing electrical signals that are on or off.
Glossary Print quality The LQ has two types of print quality: draft and Letter Quality. Draft is for high-speed, draft quality jobs; Letter Quality is for final, polished correspondence. Proportional printing Printing in which the width of the character varies from character to character. Therefore, a capital W, for example, receives much more space than a lowercase i. RAM Random Access Memory. The portion of the printers memory used as a buffer and for storing user-defined characters.
Glossary Tractor The part of the printer that moves continuous paper through the printer. 12 pitch A pitch with 12 characters per inch. User-defined characters Characters defined and stored temporarily in the printer by the user. Also known as download characters.
