Introduction The EX printers combine all the well-known virtues of previous Epson Spin printers with many features normally exclusive to costly 24-pin printers. l The speed of draft printing is higher than ever-300 characters per second in draft elite and 250 in draft pica. When you have perfected a document, you can switch to one of two Near Letter Quality fontsRoman or Sans Serif.
About this Manual To make it easier to set up your new EX-800 or EX-1000, this manual includes a 10-step guide. This guide, which is printed on the inside of the back flap, summarizes the first chapter’s setting up instructions. The blue-edged divider pages are another aid to using the manual. They make it easy to find the section of the manual you need. In addition to Setting Up Your printer, there are four other sections.
Chapter 1 Setting Up the Printer Setting up your EX printer is easy Simply follow the steps in this chapter. Note Although this manual covers both the EX-800 and the EX-1000, the illustrations show only one printer (the EX-800) because the only difference between the two is that the EX-1000 can use wider paper. 1 Unpacking the Printer As you unpack the printer, see that all the parts in Figure l-l are there and that none of them has been damaged during transportation.
Caution Do not plug in the power cord yet. You should perform the first three steps before you plug in the printer and turn on the power, Remove the tape that holds the dust cover in place during shipping and take the cover off the printer. Simply tilt the dust cover up and lift it off. Installing the paper feed knob Install the paper feed knob on the right side of the printer, as shown in Figure 1-2.
When you are finished unpacking, put the packaging materials and the head protector in the box and keep them in case you need to transport the printer. Full details on transporting the printer are in Appendix D. 2 Choosing a Place for the Printer The printer must be close enough to the computer for the cable to reach. Also keep the following tips in mind: l Place the printer on a flat, stable surface-never on a chair or any other unstable support.
WARNING The power must be OFF when you move the print head. Otherwise, you may damage the printer mechanism. Also, if you’ve been using the printer just before changing the ribbon cartridge, be careful not to touch the print head because it becomes hot during use. 3. Move the print head carriage to about 25 on the ruler on the paper bail. 4. Remove the ribbon cartridge from its packaging and tighten the ribbon by turning the knob in the direction of the arrow, as shown in Fire 1-4. 5.
8. Turn the ribbon tightening knob again to see that the ribbon moves freely Replacing the ribbon . . . The EX-800 uses a continuous-loop, inked fabric ribbon. When your printing becomes too light, replace the whole ribbon cartridge. Always use replacement ribbons designed specifically for Epson EX printers. It is not possible to use ribbons for any other series of printer, and you should never try to re-ink the ribbon.
Now, turn the power ON with the switch on the left side of the printer. When you turn on the printer, several important things happen: l The print head moves back and forth and stops at the left side of the printer; this is the home position. l The ribbon carriage moves up and down to set the ribbon at the correct level for printing. l The printer is initialized and set to certain default settings (which are fully described in Appendix E). l The green power light on the control panel comes on.
The buttons There are three buttons on the right side of the control panel. ON LINE The green light next to this button indicates that the printer is able to receive and print data from the computer. When the light is off, the printer is off line and cannot receive any data. Press the button to change from on line to off line or from off line to on line. The printer automatically goes off line when you try to print without paper in the printer.
6 Installing the Paper Guide You can install the paper guide in two different positions. Right now you need to install it to support a single sheet. Before you begin, remove the dust cover so that you can see what you are doing. The edge tab First, put the edge tab into the guide. Squeeze it together as shown in Figure 1-8 and insert the tab into the groove. Then move the edge tab so that it is about 1 ¾-inch from the left edge of the paper guide. The paper guide Second, install the guide itself.
7 Loading Paper Even if you normally use continuous paper, it is simpler to test the printer using a single sheet of paper. If you have an EX-1000, be sure to use 14-inch-wide paper so that none of the self test prints on the platen. Paper loading icons... Roth levers on the EX have icons (small pictures) beside them. These icons (shown below) remind you whether to push the lever back or pull it forward when you load paper. Now load a sheet of paper: 1. Turn the printer ON first.
5. Place the paper on the paper guide with its left edge next to the edge tab as shown in Figure 1-10 below. Push the paper firmly into the printer, then let go of it. 6. Pull the paper bail lever forward to the single-sheet loading position (indicated by the icon). This makes the paper feed into the printer until it is past the paper ball. 7. When the paper stops, push the paper bail lever back to the printing position. This makes the paper feed backward until only its top edge is under the paper bail.
8 Running the Self Test The EX has a built-in self test that prints out the characters in its memory so that you can see that the printer is working properly The self test also prints the settings of the printer’s DIP switches. This part of the printout will be useful in the next section of this manual.
To run the same test in the draft mode, hold down the LINE FEED button instead of the FORM FEED button while you turn the printer on. The EX cannot print a draft self test, however, if the NLQ DIP switch is on. Therefore, if the Print Quality line of the self test printout says ‘Print Quality NLQ,” you cannot print a draft test without changing a DIP switch. (DIP switches are explained in Appendix E.) 9 Connecting the Printer to Your Computer Your EX printer has two separate interface connections.
The serial interface For the serial interface, you ®should use an Epson serial interface cable. Use #8239 for the Apple IIc, #8297 for the IBM* PC and compatibles, and #8293 for most other computers with a DB-25 socket, including the Apple IIe with serial interface. (Although you can use the serial interface with an IBM or compatible computer, it is usually best to connect your EX to the parallel port of an IBM or compatible computer.) The serial interface also requires the setting of four DIP switches.
The switches are in two groups of eight and are numbered from l-l to 2-8. As you can see in the example below, the first part of the self test shows the settings of the switches. Condensed Zero CG Table MODE Print Quality Country Page Length Sheet Feeder Skip-Over-Perf. Auto LF Interface OFF 0 Italic ESC/P Draft U.S.A. 11” OFF OFF OFF Parallel You will find your own self test printout helpful as you use this section.
If the interface line does not say Parallel, turn switches 2-5 and 2-6 OFF If you are using a serial interface, turn to Appendix C, which gives full information on serial interfaces. The operating mode ™ The EX has two operating modes, ESC/P and IBM printer emulation mode. ESC/P stands for Epson Standard Code for Printers, a powerful set of commands developed by Epson and supported by almost all application software for personal computers.
The Epson character graphics set Half of the characters used by IBM PCs and compatibles are special character graphics and international characters. On most previous Epson printers, these characters printed as italics. With the EX, however, you can print the character graphics without losing italics or any of the power of the Epson commands. DIP switch 1-3 controls the choice between the italic character and graphic character tables (called CG table in the DIP switch printout).
Other DIP switch settings Appendix E summarizes all the DIP switch settings in a group of tables. See that appendix for reference or further information.
1-18 Setting Up the Printer
Chapter 2 Choosing and Loading Paper The EX printer can accommodate many different sizes and types of paper, using either its automatic singlesheet loading feature or its builtin adjustable tractor. The tractor is easy to use and can handle a wide range of paper widths. The automatic singlesheet loading feature handles individual sheets quickly and easily, and for greater efficiency you can add an optional automatic sheet feeder.
whenever required, making single sheets as easy and convenient to use as continuous paper. The automatic sheet feeder has its own user’s manual. Reloading during printing When you print a document more than one page long using single sheets of paper, there are two different ways your software can allow you to load a new sheet at the end of a page. l If your software sends characters in a continuous stream, the printer stops printing when it reaches the bottom of the paper and sounds the beeper.
Clear enough space around the printer so that the paper has an unobstructed path in and out of the printer. There are three common methods of arranging a printer and continuous paper: l Using a printer stand with the paper stacked underneath it. l Using a desk or table as a stand, with the printer near the rear edge and the paper on the floor or on a shelf. l Putting the printer on a desk or table and stacking the paper behind the printer. Now follow these steps to load continuous paper in your EX. 1.
5. Move the left sprocket unit all the way to the left and pull the locking lever forward to hold it in position. Note With the sprocket unit in this position, you always have a margin at the left side. If you want to print without a left margin or if your software creates a margin, move the left sprocket unit about 3/4 inch from the left side, so that the perforated edge of the paper fines up with the number 1 on the ruler on the paper bail. Check the exact position when you finish loading. 6.
10. If the paper is straight and has no wrinkles, lock the right sprocket unit in place. 11. Turn the paper feed knob slowly to feed the paper under the metal plate in front of the tractor. (The diagram on the metal plate shows how the paper should go through.) See that the paper does not wrinkle after it reaches the platen. 12. Turn the knob until the paper is past the paper bail. Then push back the paper bail lever (the lever on the right side).
Setting the top of form position Finally so that the printer does not print on the perforations, you need to establish a top of form position. The top of form position is the position of the paper when the power is turned on. This position is also reset whenever software initializes the printer or sets the page length. Setting the top of form position is a simple threestep process: 1. See that the printer is turned off. 2.
Remember that you should never advance the paper using the paper feed knob while the power is turned on. You can damage the mechanism of the printer, and the printer will lose track of the top of form position. Loading Labels If you want to use labels on a continuous backing, always choose the type that are mounted on a perforated backing sheet for use with the tractor. Labels on a shiny backing sheet will almost always slip a little if fed by friction alone.
The Paper Thickness Lever You can adjust the EX to accommodate different thicknesses of paper. You need to do this when you print labels or carbon copies. Before moving the paper thickness lever, always turn off the power, open the dust cover, and move the print head to the middle of the printer, The paper thickness lever has four positions. You can identify these by looking at the catch positions in the metal plate, as shown in Figure 2-7.
Chapter 3 Using the EX with Application Programs Now that you’ve set up and tested the printer, you need to start using it with your application programs. Printer Selection Menus 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.
Note If your application program does not list the EX printers, you may want to contact the manufacturer to find whether an update is available. A quick test After setting up your application program, print a sample document to be sure the program and the EX 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 Appendix D.
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.
This method is normally restricted to features that can be found on almost all printers, such as bold and underlining. Some programs also provide a way of placing complete printer commands in the text. These commands may or may not be visible on your screen. This method has the advantage of allowing you to use any printer command, not just a limited set. To make use of it, however, you need to understand how to use the printers commands.
A major concern for printing spreadsheets is the width of the printer. The EX-800 is an 80 column printer, and the EX-1000 is a 136 column printer, but by using condensed elite (explained in Chapters 4 and 5) you can print up to 160 columns on the EX-800 and 272 on the EX-1000. Therefore, if your spreadsheet asks the number of columns your printer can print, you can specify 160 or 272.
If you’re using the program’s print facility recheck the EX’s Command Summary to make sure you’re sending the correct commands. q If you’re still having difficulty printing, check the troubleshooting section in your spreadsheet program’s manual or Appendix D of this manual. Graphics Programs The EX is capable of producing finely detailed graphic images in black or in color (with the optional color kit).
If, on the other hand, you’ve set up a program to send a certain command to the printer, but it’s not printing correctly you could send the same command with a programming language to find whether the problem lies with your application program, the command, or the printer. Sending printer commands with BASIC You can send printer commands with any programming language. The examples in this manual are written in BASIC, because BASIC is included with most computer systems.
3-8 Using the EX with Application Programs
Chapter 4 SelecType The SelecType feature allows you to choose printing features from the control panel. It provides an easy way of enhancing documents without having to learn complex software commands, and it lets you make print style decisions when you print instead of when you edit.
The SelecType Panel The SelecType touch panel (shown in Figure 4-1 below) has eight buttons that control the basic style and size of the text you print. When you press a button, it beeps and lights up to confirm your choice. These buttons are arranged in three groups. The first group of buttons selects the print quality and font. The EX has one draft font and two NLQ (Near Letter Quality) fonts: Roman and Sans Serif. To select one of these fonts, simply press the button for the one you want.
If you try to combine proportional with condensed, proportional will override condensed, no matter which you choose first. When you have selected condensed and then press the proportional button, it beeps three times to tell you that it is overriding condensed. (The condensed button light goes off also.) If you have selected proportional and then press the condensed button, it beeps three times to tell you that you cannot select condensed without changing to pica or elite first.
If your application program changes your SelecType settings, you have two choices: 1. Use the program’s setup procedure (which could be called by another name, such as install) to remove the codes that interfere with your SelecType settings. 2. Use the print control codes for your application program instead of SelecType to control your printing. The manual for your program tells you how to change the printing style.
Chapter 5 EX Printer Features You can obtain many different printing effects with the EX printer, from arranging the printout on the paper to using color or giving extra emphasis to particular words and phrases. This chapter shows you the features you may want to select with your software. Once you have read about the features, you can find their commands in the Command Summary SelecType, as you know, controls the printing style of a whole document.
Print Size and Character Width To add greater variety to your documents, the EX has two pitches as well as proportional spacing and condensed printing. All four can be selected either with SelecType or a software command, and software commands also offer one other option: doublewidth printing. Pitches and Proportional Spacing The two pitches are pica and elite. Pica is 10 characters per inch (cpi) and elite is 12 cpi. The printout below shows the difference between the tW0.
Pica and elite can be reduced to about 60% of their normal width with the condensed mode. This mode is particularly useful for printing wide spreadsheets because condensed elite allows you up to 160 characters on an 8-inch line and 272 on a 13½-inch line. Condensed can be selected with SelecType, by setting a DIP switch (see Appendix E), or with a software command. Even if you turn condensed on with the DIP switch, you can still turn it off with SelecType or the software command.
Superscripts and subscripts are valuable for such purposes as printing footnote numbers or parts of mathematical formulas, and the underline mode provides an automatic way of underlining fully any piece of text. It underlines spaces, subscripts, and superscripts without a break. The example below shows underlining with text and combined with superscripts and subscripts in a mathematical formula. Using Different Character Sets The EX incorporates a new character set: Epson Character Graphics.
The other important change you can make to the standard character set is to change some characters for ones commonly used in other languages-chiefly European and Scandinavian-such as accented characters and symbols. In Epson mode, eight international character sets can be selected by setting DIP switches 1-6 to 1-8: USA, French, German, UK, Danish, Swedish, Italian, and Spanish. See Appendix E for the DIP switch settings. In Epson mode, these eight, and five more, can also be selected by a software command.
5-6 EX Printer Features
Chapter 6 Graphics and User-defined Characters The dot graphics mode allows your EX to produce pictures, graphs, charts, or almost any other pictorial material you can devise, and the user-defined character feature allows you or a commercial software program to put special characters in the EXs memory so that it can print them just as if they were ordinary letters.
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 EX prints graphics, read on. The Print Head To understand dot graphics you need to know a little about how the EX's print head works. The EX's print head has nine pins. As it moves across the page, electrical impulses cause the pins to fire.
Dot patterns The EXs print head is able to print graphics in addition to text because graphic images are formed on the EX 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.
To fire any one pin, you send its number. To fire more than one pin at 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, then send 129. By adding the appropriate label numbers together, you can fire any combination of pins.
The graphics command format There are several different graphics commands giving different horizontal dot densities and printing speeds. Because the format is almost the same for all the commands, however, the example here keeps things simple by using only the singledensity graphics command, ESC K. In single-density graphics, there are 60 dots per inch horizontally The command to enter singledensity graphics mode is ESC K nl n2.
Graphics data After receiving a graphics command such as ESC K nl n2, the printer prints the number of codes specified by nl and n2 as graphics data, no matter what codes they are. This means that you must be sure to supply exactly the right amount of graphics data. If you supply too little, the printer will stop and wait for more data and will seem to be locked. The next data sent will then be printed as graphics, even if it is really text.
WIDTH statements Some software (including most versions of BASIC) automatically inserts carriage return and line feed codes after every 80 or 130 characters. This is usually no problem with text, but it can spoil your graphics. Two extra columns of graphics are printed in the middle of the ones you send, and are left over and printed as text. In some versions of BASIC you can prevent unwanted control codes in graphics by putting a WIDTH statement at the beginning of all graphics programs.
1. The computer is prevented from adding any extra characters by the WIDTH statement (line 100). 2. The line spacing is changed to 8/72 of an inch-the height of the dot patterns used in the program (fine 110). 3. The program goes through the graphics commands the required number of times (fines 120 and 170). 4. A new graphics command is used for each line printed (lines 130-160).
Modes 4-7 in the table are special modes that alter the horizontal density to give proportions of a computer monitor (the CRT modes), or to match the vertical density so as to give round circles (the plotter modes). In two modes, high-speed double-density and quadruple-density the print head cannot print two consecutive dots with the same pin, so that it can print dots in only half the possible dot positions in any one row.
A little experimentation should tell you whether the reassigning code can improve your graphics printouts. Designing Your Own Graphics This section takes you through the development of a graphics program. The example is not especially complicated, but it does include the same steps you would use for a more complex figure. You should plan your figure with dots on graph paper, but before beginning to place the dots, you must decide which graphics density you want.
Now look at Figure 6-3, a design for a high-speed doubledensity design. It should point you in the right direction for your own designs. 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 in figure 6-4.
The numbers for the second line were calculated in the same way Once the numbers for the pin patterns are calculated, they are put in the program in DATA statements, separated by commas. The program works in a similar way to the last example. This time it selects 7/72-inch line spacing because only seven pins are used. Because the data is not repetitive, each column of graphics data is read from the DATA statements and sent to the printer. The design is 41 dot positions wide.
User-defined Characters The EX has a command that allows you to define and print characters of your own design. You can design an entirely new alphabet or typeface, create mathematical or scientific symbols, or create graphic patterns to serve as building blocks for larger designs. These user-defined characters work only in draft mode. Also, you can buy commercial software programs that assist you in creating characters or supply you with sets of characters already created.
eight of them in a single user-defined character. The design in Figure 6-5 uses the top eight, but you can also use the bottom eight by using the grid on the right as explained later in this section. Once the character is planned on the grid, you simply add the pin values for each column together, just as you do for graphics. Then, the next step in defining a character is to send this information to the printer.
Following the specification of the range of characters to be defined in this command is one number (al) that specifies the width of the character and whether it uses the top eight pins or the bottom eight pins. The last part of the character definition is the actual data that defines the dot patterns for each column of each character. Since a character can use up to eleven columns, you must supply eleven data numbers for each character even if some of the columns are blank.
Run the program to see the printout below: As you can see, both sets of characters (the original ROM characters that the printer normally uses and the user-defined character set) remain in the printer available for your use. The command to switch between the two sets is used in lines 180 and 200 and has the following format: ESC%n If n is 0, the normal ROM character set is selected. (This is the default.) If n is 1, the user-defined character set is selected.
Note This command will cancel any user-defined characters you have already created. You must send this command to the printer before you define characters. Specifying the width and height The example program uses 136 for al (in line 130 of the definition program), but you can use other values. The number al specifies two things: the width of the character and its position on the grid. The width is used when the character is printed in proportional mode.
The sample below shows the heart character printed in various styles. Other considerations Keep in mind that user-defined characters are stored in RAM, which is not permanent. Whenever the printer power is turned off or your computer sends an initialization (INIT) signal, all of the user-defined characters are lost. For example, some computers send an INIT signal each time BASIC is loaded or when certain application programs start up, and most computers do it if you have to reset them.
Appendix A Command Summary This appendix lists and describes all the commands, both Epson (ESC/P) mode and IBM printer emulation mode, available on the EX. This summary is in two parts. The first part lists each command in numerical order and gives the page number where it is fully described in the second part of this appendix. If you know which command you are looking for, consult the numerical list to find the page number where it is described.
Note Some application programs can use control key sequences. See the Control Key chart on page A-3 for information on using these.
Control key chart Some application programs can use control key codes for decimal values 0-27. 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. Some programs that use this system cannot use controls, and many programs use the control keys for other purposes.
Commands in Numerical Order This section lists all the EX commands, with their decimal and hexadecimal values. The numbers in the columns on the right are the page numbers in this appendix where a complete description of the command can be found. If the Epson and IBM printer emulation mode page numbers are the same, the command is the same in both modes and is described only in the Epson mode section.
Command Summary A-5
A-6 Command Summary
Epson (ESC/P) Commands The following section lists and describes all the Epson (ESC/P) commands. Printer Operation Comments: Resets the printer mode and clears the buffer of printable data on the print line preceding the command. Selection select Printer DC1 Format: DC1 ASCII code: 17 Decimal: Hexadecimal: 11 Comments: Returns the printer to the selected state if it has been deselected by the printer deselect code (DC3).
Deselect Printer DC3 Format: ASCII code: DC3 19 Decimal: Hexadecimal: 13 Comments: Puts the printer into the deselected state until select printer code (DCl) is received. The printer cannot be reselected with the ON LINE button. Speed ESC 8 Turn Half-speed Mode On/Off Format: n ASCII code: ESC 27 115 n Decimal: Hexadecimal: 1B 73 n Comments: The following values can be used for n: 1: Mode is turned ON.
Turn Immediate Mode On/Off ESC i Format: ASCII code: ESC i n 105 n 27 Decimal: Hexadecimal: 1B 69 n Comments: The following values can be used for n: 1: Mode is turned ON. 0: Mode is turned OFF In this mode the printer prints on a character by character basis rather than line by line as in the normal print mode. It also moves the paper up so that the user can see the printing and then moves it back down. This command is ignored if the automatic sheet feeder is selected.
ESC U Turn Unidirectional Mode On/Off Format: ASCII code: ESC U n 27 Decimal: Hexadecimal: 1B Comments: The following values can be used for n: 1: Mode is turned ON. 0: Mode is turned OFF Printing is normally bidirectional. This command selects unidirectional printing for more accurate positioning during text or graphics printing.
Turn Automatic Sheet Feed Mode On/Off ESC EM Format: ASCII code: ESC EM n 27 25 n Decimal: Hexadecimal: 1B 19 n Comments: The following values can be used for n: 4: Mode is turned ON. 0: Mode is turned OFF The command should not be used unless the automatic sheet feeder is installed. It is ignored if any value other than “0” or “4” is used for n. The command overrides the setting of DIP switch 2-2. The variables are the characrers “0” (48 decimal or 30 hex) and “4” (52 decimal or 34 hex).
Comments: Sets the MSB bit of all incoming data as 1. Comments: Cancels the MSB control set by ESC = or ESC >. Comments: Sounds the printer’s beeper.
Data Control Comments: Prints the data in the buffer and returns the print position to the left margin. A line feed may be added if DIP switch 2-4 is ON or the AUTO FEED XT line on the parallel interface is held LOW. Comments: Removes all text on the print line, but does not affect control codes. Comments: Removes the last text character on the print line but does not affect control codes.
Vertical Motion Comments: Prints the data in the print buffer and advances the paper to the top of the next form according to the current page length. Sets the page length to n lines in the current line spacing. The value of n must be from 1-127. The top of form position is set to the current line. Sets the page length to n inches. The value of n must be from 1-22. The top of form position is set to the current line.
Comments: The variable n is the number of lines skipped between the last line printed on one page and the first line on the next page. For example, with the standard settings for line spacing (1/6inch), and page length (66 lines), ESC N 6 causes the EX to print 60 lines and then skip 6. DIP switch 2-3 performs the same function. This setting is cancelled by ESC C or ESC C NUL The value of n must be from 1-127. Comments: Cancels the skip-over-perforation set by ESC N.
ESC O Format: Select 1/8-inch Line Spacing Comments: Sets the line spacing to l/8 of an inch for subsequent line feed commands. The 0 is the digit zero and not ASCII code 0. Comments: Sets the line spacing to 7/72 of an inch for subsequent line feed commands. The 1 is the digit one and not lower case L or ASCII code 1. Comments: Sets the line spacing to l/6 of an inch for subsequent line feed commands. The “2” is the digit two and not ASCII code 2. This is the default at power on.
Esc 3 Format: Select n/216-inch Line Spacing Comments: Sets the line spacing to n/216 of an inch for subsequent line feed commands. The “3” is the digit three and not ASCII code 3. The value of n must be from 0-255. ESC A Format: Select n/72-inch Line Spacing Comments: Sets the line spacing to n/72 of an inch for subsequent line feed commands. The value of n must be from 0-85.

Appendix C The Serial Interface This appendix has the information you need to use the EX's built-in serial interface. It includes DIP switch settings, problem solving, and technical specifications. The information on the built-in parallel interface is in Chapter 1 and Appendix G, and the information on optional interfaces is in Appendix E WARNING Two interface cables should not be plugged into the printer at the same time. This may damage your printer.
For the parity setting you have three choices: odd, even, or nonparity Use either odd or even unless your computer requires non-parity Again, be sure that the settings on your printer and computer match. Setting the Switches The interface you use and the type of parity check for a serial interface are set with DIP switches 2-5 and 2-6: Table C-1. Interface type DIP switches 2-7 and 2-8 determine the baud rate when the built-in serial interface is used.
Troubleshooting for Serial Interfaces Recommendation Problem Printer prints one character then stops The EX uses the DIR signal and the X-on/X-off protocol (via TXD) to tell the computer whether it is ready to receive characters or whether it is busy printing. Refer to your computer’s documentation and ensure that the computer is using one of these systems. You may also need to check your cable wiring or ask your dealer to do it for you.
Handshaking Handshaking by DTR signal or X-on/X-off. The DTR signal changes to “mark”-meaning the printer is not ready to receive data-when the number of bytes free in the input buffer goes down to 256. The signal changes to “space”-meaning that the printer is now readywhen the number of bytes free in the input buffer rises to 528. Error handling All errors are ignored. Connector 6-pin DIN connector. In this table, the direction of signals is given relative to the printer. Table C-3.
Appendix D Problem Solving and Maintenance This appendix presents solutions for possible problems, explanations of the EX's advanced features, and tips on maintaining and transporting your printer. General Troubleshooting Recommendation Problem Printer does not print Make sure that the printer is turned on and is on line. Both the POWER and ON LINE lights should be on. Make sure that the printer and computer are connected. Be certain you are using the correct cable.
Recommendation Printing is patchy, faint, uneven, or intermittent Check that the ribbon is seated correctly and that the pins at either side are located properly in the holes in the ribbon carriage. Check that the ribbon moves freely in the cartridge. If you have been using the ribbon for a long time or for a large amount of printing, it may need replacing. It is also possible for the print head to wear out if the printer is used frequently and for long periods at a time.
Recommendation Problem Self test pattern is garbled If the test pattern did not print as shown in Chapter 1, the printer is faulty Refer the problem to your dealer. If the pattern is printed but is patchy or faint, check that the ribbon is installed correctly Beeper sounds and printer stops If the READY light is off and the ON LINE light is flashing, the EX has stopped to allow the head to cool. Printing will soon resume; you do not have to do anything to restart it.
Data Dump Mode The EX has a special feature that makes it easy for experienced printer users to find the causes of problems. The hexadecimal (hex) or data dump mode gives a printout of exactly what codes reach the printer. Enter this mode by turning on the printer while holding down the FORM FEED and LINE FEED buttons at the same time.
In this way you can quickly determine that prior to printing, the word processor sent seven commands to set up the printer followed by a BEL character to sound the beeper. If you find code-s in your data dump that you did not enter in your program or codes you did not expect your application program to send, your computer may be changing the codes before sending them to the printer. If so, you need to adjust the program.
The extra line feed character is usually no problem, unless you want to send ASCII code 13 on its own as part of a graphics statement or a character definition. To do this, use the OPEN statement to assign a file number to the printer (LPTl:) and use the PRINT# statement in place of LPRINT You also need to use a slightly different WIDTH statement. To prepare the printer in this way use a line like this: A third problem exists with IBM PC BASIC release 2.0.
patchy If this happens suddenly or long before the expected lifetime is over, the problem is almost certainly connected with another component of the printer. As soon as the print head fails, stop using the printer and contact your Epson deafer for a replacement head. Do not attempt to replace the head yourself because the printer should also be tested to make sure that no other parts are damaged.
D-8 Problem Solving and Maintenance
Appendix E Defaults and DIP Switches This appendix lists all of the default settings and lists and explains the settings of all the DIP switches. Default and Initialization Settings The EX can be initialized (returned to a fixed set of conditions) in three different ways: when it is turned on, when it receives an INIT signal at the parallel interface (pin 31 becomes LOW), and when it receives the ESC @ command. The following conditions are always reset: l The print head returns to the home position.
DIP Switch Settings The EX has sixteen DIP (Dual In-line Package) switches that allow you to change many of the printer’s settings to suit your individual needs. The DIP switches are in two groups of eight, mounted on the back panel, as shown in Figure E-l. Each set of switches is numbered from 1-8 so that DIP switch l-l is the switch at the far left side and the one at the far right is DIP switch 2-8.
The following tables describe the switches and their functions. In each case the shaded settings are those set at the factory The first two tables summarize the two groups of switches. The remaining three show how some of the DIP switches work in combination to let you choose from a wide selection of options. Table E-1. DIP switch group1 Table E-Z. DIP switch group 2 Note: Shaded items are the factory settings.
International Character Sets Thirteen international character sets are available in Epson mode. Eight of these are selected by DIP switches 1-6 to 1-8 and the remaining five (Japan, Norway, Denmark II, Spain II and Latin America) can be selected with the ESC R command, which is described in the Command Summary For the characters available in each character set, see Appendix B.
Interface Selection The type of interface and the type of parity check for a serial interface are set with DIP switches 2-5 and 2-6: Table E-4. Interface type DIP switches 2-7 and 2-8 determine the baud rate when the built-in serial interface is used. They have no effect on any optional interfaces, or on the built-in parallel interface. Therefore, if you use the serial interface only occasionally, you can still leave these switches set as you want them. Table E-5.
E-6 Defaults and DIP Switches
Appendix F Choosing and Setting Up Optional Interfaces This appendix contains information on Epson interfaces compatible with EX printers, instructions on choosing the right interface for a particular job, and instructions for installing internally mounted interface boards. Compatible Interfaces You can use a number of optional interfaces that supplement the EX's built-in parallel and serial interfaces and the standard 8K data buffer.
Choosing an Interface This section describes the interfaces. IEEE-488 and Apple interfaces The IEEE-488 system allows you to connect computers, printers, and other peripherals so that they can share data freely Epson offers two types of IEEE438 interfaces. The #8161 offers the basic ability to operate in the IEEE-488 address and listen-only modes. The #8165 has the basic features and an 8K data buffer and a line monitor function, which provides a diagnostic printout of IEEE-488 commands.
Three Epson serial interfaces are suitable for EX printers. All three offer a wide range of baud rates, a choice of 7-bit or 8-bit data, and support Current Loop operation in addition to RS-232C. They also offer a choice of other features, which are listed in Table F-2. Table F-2.
Installing an Interface Before installing an interface, you must remove the printer’s cover, WARNING Do not remove the cover unless the printer is turned OFF because high voltages are present inside the printer when the power is on. Also do not touch contacts on the circuit board of the printer because many of the components can be destroyed by the static electricity charge that may build up on your body 1.
6. With the printer facing you, unclip the left side of the control panel and lift it up slightly to release it from the case (Figure F-2). 7. At each side of the front panel there is a retaining clip, as shown in Figure F-3. One is reached through the control panel opening. Reach behind the cable and gently press the two clips to release the front edge of the upper case. 8.
Inserting the Interface Board 1. Remove the upper case of the printer, following the steps described in the previous section. 2. Remove the blanking plate above the parallel connector (as shown in Figure F-5) to allow access to the new interface connector when the case is reassembled. 3. Locate the three supports on which the interface board will rest, and the screw at the rear of the circuit board labelled FG. These are also shown in Figure F-5.
Serial Interface Settings If you are using an optional serial interface, you may need to change the communications protocol of the printer or the computer for them to communicate properly The protocol used by the printer is decided by one or two groups of DIP switches located on the serial interface board; the protocol used by the computer can probably be altered by a software command. It is essential that the printer and computer use compatible protocols.
The three following tables contain all the information you need for the optional interface settings.
Appendix G Technical Specifications This appendix contains the specifications for the EX-800 and the EX-1000, including the built-in parallel interface. For the specifications for the built-in serial interface, see Appendix C.
Paper Number of copies Up to 3 sheets, including the original. Total thickness not to exceed 0.16mm Paper width Continuous feed Single-sheet Roll 4” to 10” 7.15” to 8.5” 8.
Electrical Voltage: 120V AC Consumption 120 VA Frequency 49.5 Hz - 60.5 Hz Insulation resistance 10 Mohms between AC power line and chassis Dielectric strength Can withstand 1 kV rms applied between AC line and chassis for 1 minute, or 1.
Parallel Interface WARNING Two interface cables should not be plugged into the printer at the same time. This may damage your printer. For the specifications of the serial interface, see Appendix C. Connector pin assignments and a description of respective interface signals are shown in Table G-1.
Notes: 1. The column heading “Direction” refers to the direction of signal flow as viewed from the printer. 2. “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.
3. All interface conditions are based on TTL level. Both the rise and the fall times of each signal must be less than 0.2 microseconds. 4. Data transfer must be carried out by observing the ACKNLG or BUSY signal. (Data transfer to this printer can be carried out only after receipt of the ACKNLG signal or when the level of the BUSY signal is LOW) Data Transfer Sequence Interface timing Figure G-1 shows the timing for the parallel interface.
