Removing the Protective Materials
The printer is protected during shipping by pieces of white packing
material. Also, the wide carriage printer is protected by a locking
clip, which must be removed before you turn on the printer.
CAUTION: Before turning on the wide carriage printer,
be absolutely sure you have removed the locking clip.
Turning on the printer while the clip is attached may
seriously damage the mechanism.
Follow these steps to remove the protective materials.
1. Remove the printer cover.

Setting Up the Printer
Choosing a Place for the Printer
There are several important things to consider when selecting a
place to set up your printer. Keep the following in mind:
Place the printer on a flat, hard, stable surface. A soft surface,
such as a padded counter or carpeted area, will block the
ventilation slots and may cause overheating.
Place the printer close enough to the computer for the printer
cable to reach.
Leave adequate room around the printer to allow for easy printer
operation and maintenance, and for unrestricted flow of air
around the printer.
Use a grounded outlet; do not use an adapter plug.
Avoid locations that are subject to direct sunlight, excessive heat,
moisture, or dust.
Avoid electrical outlets controlled by wall switches or automatic
timers. Accidental interruption of power can wipe out
information in both your computer’s and printer’s memory.
Avoid using outlets that share a circuit with large motors or
electrical appliances; this could cause fluctuations in line voltage.
Keep the entire computer system away from potential sources of
electromagnetic interference such as loudspeakers or the base
units of cordless telephones.
Setting Up the Printer
1-5
The illustration below shows a good printer location.
Note: Before using a printer stand, read these requirements and
suggestions.
l
The stand should be able to support at least twice the weight of
the printer.
l
Never use a stand that supports the printer at an angle of
more than 15 degrees from horizontal.
l
With a cut sheet feeder, your printer must be kept level.
l
If your paper supply is positioned below the printer stand,
make sure there is enough clearance to keep the paper from
catching on the underside of the stand. Also, make sure the
distance between the stand supports is wide enough for the
paper you are using.
l
Position your printer’s cables so that they do not interfere with
paper feeding. If possible, secure the cables to the printer stand.
1-6
Setting Up the Printer
Assembling the Printer
After you’ve decided on the best place to set up your printer, the
next step is to install the platen knob.
Installing the Platen Knob
The platen knob is used to feed the paper manually in the event of a
paper jam or other paper feeding problem. The platen knob is packed
in an indentation in the printer’s white foam packing material.
1. Insert the knob into the hole on the printer’s side and rotate it
slowly until it slips onto the shaft.
Setting Up the Printer
1-7
2. Push firmly on the platen knob until it fits against the printer case.
CAUTION: Do not use the platen knob to adjust the
position of the paper. This interferes with the automatic
paper loading system and may cause a paper jam.
Installing the Ribbon Cartridge
Your printer’s ribbon cartridge is designed for easy installation and
removal. Before installing the ribbon cartridge, make sure the printer
is turned off.
Install the ribbon cartridge as follows.
1-8
Setting Up the Printer
Assembling the Printer
1. Slide the print head to the middle of the printer.
CAUTION: Never move the print head while the printer is
turned on because this can damage the printer. Also, if you
have been using the printer, the print head may be hot; let
it cool for a few minutes before touching it.
2. Turn the ribbon-tightening knob in the direction of the arrow.
This removes slack in the ribbon and makes it easier to install.

3. On the standard width printer, open the paper tension unit
cover. (On the wide carriage printer, you already removed the
paper tension unit when you removed the locking clip.)
4. Hold the ribbon cartridge by its handle and push it firmly down
into position, making sure the plastic hooks fit into the slots.
Note: Press lightly on both ends of the cartridge to make sure
the plastic hooks are properly seated.

Setting Up the Printer
5. Use a pointed object, such as a ball point pen, to guide the ribbon
between the print head and ribbon guide while you turn the
ribbon-tightening knob to help feed the ribbon into place.
6. Slide the print head from side to side to make sure it moves
smoothly. Also check that the ribbon is not twisted or creased.

Setting Up the Printer
9. Press down on both sides of the paper tension unit to lock it in
place.
Attaching the Paper Guide
When you use single sheets, the paper guide helps to feed the paper
smoothly and efficiently into the printer. Attach the paper guide
using the following procedure.
1. Place the paper guide on the printer.
Setting Up the Printer
1-13
2. Raise the paper guide until it locks into place.
Note: To lower the paper guide, lift up slightly to release it
from its locked position; then gently lower it down onto the
printer.

Testing the Printer
Now that your printer is fully assembled, you can use its built-in self
test function to see that the printer is working correctly before you
connect it to a computer. You should perform this test to make sure
that your printer was not damaged during shipping and that the
ribbon is correctly installed.
Before running the self test, you need to connect the printer to an
electrical outlet and load a sheet of paper.
Plugging in the Printer
1. Make sure that the printer is turned off.
2. Plug the power cable into a properly grounded electrical outlet.
Running the Self Test
The self test can be run in the draft or Letter Quality mode,
depending on which button you hold down as you turn on the
printer.
Setting Up the Printer
1-15
The self test is 8 inches wide on the standard width printer and
14 inches wide on the wide carriage printer.
CAUTION: Never run the self test using paper that is
narrower than 8¼ inches (210 mm) on the standard width
printer or 14 inches (360 mm) on the wide carriage printer.
This prevents the print head from printing directly onto
the platen, which can damage the print head.
Although the self test can be run with continuous paper, use a single
sheet of paper now because single sheet loading is easier.
1. Make sure the printer is turned off.
2. Push the paper release lever back to the single sheet position.
1-16
Setting Up the Printer
3. While holding down the LINE FEED button (draft mode) or
FORM FEED button (Letter Quality mode), turn on the printer. The
printer beeps several times and POWER and PAPER OUT lights
come on.
4. Move the left edge guide so that it locks in place next to the
guide mark.
5. Adjust the right edge guide to match the width of your paper.
Setting Up the Printer
1-17
6. Next, slide a sheet of paper down between the edge guides until
it meets resistance. After about two seconds, the printer loads the
paper automatically and then starts the self test.
Note: If the platen turns without loading the paper, press the
ON LINE button to take the printer off line. Then remove the
paper and reinsert it more firmly.
A list of DIP switch settings is printed first, followed by a series
of characters. The self test continues until the paper runs out or
until you press the ON LINE button.
1-18
Setting Up the Printer
7. When you wish to stop the test, press the ON LINE button.
8. If the paper is still loaded, press the LOAD/EJECT button or
LINE FEED button to eject it. Then turn off the printer.
CAUTION After turning the power off, always wait at
least five seconds before turning it back on. Turning the
power on and off rapidly can damage the printer.

Setting Up the Printer
Testing the Printer
If the self test does not print properly, check the control panel and
the print head area. Make sure that all packing material and
shipping restraints have been removed from inside the printer. See
Chapter 7, Troubleshooting, for other possible causes and solutions.
If the printer still does not print the self test correctly, contact your
dealer or call the Consumer Information number listed in Where to
Get Help.
Setting Up the Printer
1-21
Connecting the Printer to Your Computer
If the self test printed correctly, you are now ready to connect the
printer to your computer.
If your computer has a parallel interface and you have a suitable
shielded cable, you should be able to connect your printer
immediately. The steps below describe how to connect the parallel
interface cable.
If your computer requires another type of interface, you need to
install an optional interface board. See Interface Boards in Chapter 5.
If you are not sure which type of interface cable is required, see your
computer manual.
The Parallel Interface
Connect the parallel interface cable as described below:
1. Make sure that both your printer and computer are turned off.
2. Plug the cable connector securely into the printer.
1-22
Setting Up the Printer
3. Squeeze the wire clips together until they lock in place on either
side of the connector.
4. If your cable has a ground wire, connect it to the ground screw
beneath the interface connector.

Setting Up the Printer
Setting Up Your Application Software
Now that you have set up and tested the printer, you should make
sure that it works with your application programs.
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
menu that presents a list of printers to choose from.
If your application program has a printer selection menu, use the
instructions below.
Choosing From a Menu
Because the family of Epson printers shares a great many
commands, you can use an application program even if it does not
list your printer on its selection menu. If the printer is not listed,
choose one of the following printers. They are listed in order of
preference.
LQ-2550
LQ-2500
LQ-850 (LQ-1050)
LQ-500
LQ-800 (LQ-1000)
LQ-1500
If none of the above printers is listed, select the first one available on
the following list: LQ, EX, FX, LX, RX, MX, Epson printer, Standard
printer, Draft printer.
To use all of the features of the printer, however, it is best to use a
program with your printer on its menu. If an application program
does not list the printer, contact the software manufacturer to see if
an update is available that supports your model.

Selecting a Paper Feeding Method
The paper release lever on the standard width printer has two
positions and on the wide carriage printer has three positions for use
with the various methods of paper feeding. Make sure the paper
release lever is set to match the desired paper feeding method.
Standard width printer
Wide carriage printer
2-2
Paper Handling
Selecting a Paper Feeding Method
The lever positions are marked by icons.
Single sheet position: When you load single sheets from
either the paper guide or from the optional cut sheet feeder,
the lever should be all the way back.
Continuous feed position: When you load continuous paper
with the built-in push tractor, the lever should be all the
way forward on the standard width printer and in the
middle on the wide carriage printer.
Pull tractor position-wide carriage printer only: When you
load continuous paper with the optional pull tractor, the
lever should be all the way forward on the wide carriage
printer. Even when you use the built-in push tractor at the
same time, you must set the lever to this position. Only
select this position if you are using the optional pull tractor.
Note: On the standard width printer, the paper release lever is in
the forward position for continuous paper whether the paper is
loaded from the built-in push tractor or the optional pull tractor.
Paper Handling 2-3
Using Single Sheets
The standard width printer can accommodate single sheets with a
width of 7.2 inches (182 mm) to 10 inches (254 mm). The wide
carriage printer can accommodate single sheets with a width of
7.2 inches (182 mm) to 14.3 inches (364 mm).
If you do most of your printing on single sheets, you may find it
more convenient to install the optional cut sheet feeder. This option
automatically inserts a new sheet and can hold up to 150 pages. For
more details, see Chapter 5.
Loading Paper
1. Push the paper release lever back to the single sheet position.
2. Turn on the printer. (The green POWER light should come on.)
Note: Do not insert paper before turning on the printer.
2-4
Paper Handling
3. Move the left edge guide so that it locks in place next to the
guide mark. (You may want to change this position later,
depending on the margin settings of your application program.)
4. Adjust the right edge guide to match the width of your paper.
Paper Handling 2 - 5
Using Single Sheets
5. Slide the paper down between the edge guides until it meets
resistance. After about two seconds, the printer loads the paper
automatically and is set ON LINE so that it can accept data from
your computer.
.
CAUTION: Never advance the paper using the platen knob
while the printer is turned on. If the platen turns without
loading the paper, press the ON LINE button to set the
printer off line. Then remove the paper and reinsert it
more firmly.
You are now ready to begin printing.
2-6
Paper Handling
Reloading During Printing
When you print a document of more than one page using single
sheets of paper, the printer stops printing when it reaches the bottom
of the page. When this happens, the ON LINE light either goes off
automatically or remains on, depending on your application
program software. If the ON LINE light remains on, the first thing you
should do is press the ON LINE button to take the printer off line.
Once the ON Line light is off, remove the sheet that has just been
printed (if necessary, press the LOAD/EJECT button to eject the page)
and load a new sheet. Press the ON LINE button to start printing the
next page and follow any additional prompts from your software.
Paper Handling 2-7
Using Continuous Paper
The push tractor built into your printer is remarkably easy to load
and operate. Its low-profile design takes up little space and can
handle paper up to 10 inches (254 mm) wide on the standard width
printer and up to 16 inches (406 mm) wide on the wide carriage
printer.
Positioning Your Continuous Paper Supply
An important consideration for achieving smooth and trouble-free
paper feeding is the position of your paper supply.
Three ways of positioning your printer and continuous paper supply
are shown below.
Be sure to align the paper supply with the paper loaded in the
tractor so that the paper feeds smoothly into the printer.
Loading Continuous Paper
1. Be sure that the printer is turned off, then remove the paper
guide.
2-8
Paper Handling
2. Set the paper release lever to the continuous paper position. On
the standard width printer, this is the forward position.
On the wide carriage printer, this is the center position.

The printer remembers the loading position and advances each page
to the same position. If you need to adjust the loading position, use
the micro-adjustment feature. See Adjusting the Loading Position in
Chapter 3.
CAUTION: Never adjust the loading position using the
platen knob and never turn the platen knob while the
printer is turned on.
Note: Before you begin printing, check the page length and skip
over perforation settings; readjust the settings if necessary. See
Chapter 3 for details.
Paper Handling
2-15
Switching Between Continuous and Single Sheets
Even with continuous paper loaded in the printer, you can easily
switch to single-sheet printing without removing the continuous
paper from the tractor.
Switching to Single Sheets
To switch from continuous paper to single sheets, you remove the
last printed document and then back the continuous paper out of the
way. Follow the steps below.
1. If the printer is on line, press the ON LINE button to set the printer
off line.
2. Tear off any outgoing sheets. If the end of the last printed
sheet has not reached the tear-off edge, you need to press the
FORM FEED button to advance your document to a point where
it can be easily removed.
2-16
Paper Handling
CAUTION: Make sure you tear off your printed document
before pressing the LOAD/EJECT button. Reverse-feeding
several pages at a time may result in a paper jam. This is
especially true for narrow paper (less than 6 inches or
150 mm wide).
3. Press the LOAD/EJECT button to feed the continuous paper
backward out of the printer and into the standby position. The
paper is still attached to the tractor but no longer in the paper
path.
Note: Pressing the LOAD/EJECT button once may not feed the
paper far back enough to reach the standby position. If the
PAPER OUT light does not come on, you need to press the
LOAdD/EJECT button again. With normal-width continuous
paper, you can press the LOAD/EJECT button up to three times.
If, however, you are using narrow paper (between 4 and 6
inches or 100 and 150 mm) you should only press the
LOAD/EJECT button once. Also, do not use this button to eject
labels.
Paper Handling
2-17
Switching Between Continuous and Single Sheets
CAUTION: Never feed labels backward through the
printer. Labels can easily come off the backing sheet and

After about two seconds, the printer loads the paper
automatically and is set ON LINE so that is can accept data from
your computer.
Note: If the platen turns without loading the paper, press the
ON LINE button to take the printer off line. Then remove the paper
and reinsert it more firmly.
Switching Back to Continuous Paper
It is easy to switch back to printing with continuous paper. Before
switching to continuous paper, make sure that the single sheet is
ejected and the printer is off line.

Paper Handling
Printing on Special Paper
In addition to printing on single sheets and continuous paper, your
printer can also print on a wide variety of paper types, including
multi-part forms, labels, and envelopes.
Before printing on special types of paper, you need to change the
paper thickness setting.
CAUTION: When printing on multi-part forms, labels, or
envelopes, make sure that your application program
settings keep the printing entirely within the printable
area.
For multi-part forms and labels you should not print any
closer than one-half inch from either side of the paper.
For information on the printable area for envelopes, see
Envelopes later in this chapter.
The Paper Thickness Lever
To accommodate various thicknesses of paper, the printer is
equipped with a paper thickness lever that can be set to seven
positions (standard width printer) or eight positions (wide carriage
printer). These positions are identified by a scale on the printer next
to the lever.
To change the paper thickness setting, follow these steps.
1. Make sure that the printer is turned off. Then remove the printer
cover.
WARNING: If the printer has just been in use, the print
head may be hot. Allow it to cool before touching it.
Paper Handling
2-23
2. Slide the print head to the middle of the printer.
3. Select the paper thickness you want according to the table on the
next page. For normal use, the lever should always be set to
position 2 on the scale.
Note: If you have installed the optional film ribbon cartridge, set
the paper thickness lever to position 1.

To help you check the position of the paper thickness lever, the
orange MULTI-PART light on the control panel comes on if the
lever is set to position 4 or higher.
CAUTION: Always return the lever to position 2 when you
go back to printing on ordinary paper. Continuous
printing with the lever set at a position higher than 2 can
shorten the life of the print head. Printing past the edge of
envelopes, multi-part forms, labels, or thicker-than-normal
paper can damage the print head.
Multi-part Forms
With the built-in tractor unit, your printer can print on continuous
multi-part forms. You can use multi-part forms that have up to three
parts including the original. Make sure you set the paper thickness
lever to the proper position.
Except for the paper thickness lever setting, you load multi-part
paper the same way as continuous paper. For details, see Loading
Continuous Paper in this chapter. Also see Page Length and
Adjusting the Loading Position in Chapter 3.
2-26
Paper Handling
CAUTION: Do not use multi-part forms with the singlesheet feeding system or the optional cut sheet feeder.
Labels
If you need to print labels, always use labels mounted on a
continuous backing sheet with sprocket holes for use with a tractor.
Do not try to print labels as single sheets because labels on a shiny
backing sheet almost always slip a little.
You load labels the same way that you load continuous paper except
that the paper thickness lever must be adjusted for printing labels.
See Loading Continuous Paper earlier in this chapter. For the correct
paper thickness setting, see The Paper Thickness Lever earlier in this
chapter.
Paper Handling
2-27
CAUTION: Never feed labels backward through the
printer. Labels can easily peel off the backing and jam the
printer. Therefore, never use the LOAD/EJECT button to eject
labels. Also, never use the short tear-off function with
labels. (Be sure to set DIP switch 2-2 to off.) If a label does
become stuck in the printer, contact your dealer or call the
Consumer Information number listed in Where to Get
Help.
Because labels are especially sensitive to temperature and
humidity, always use them under normal operating
conditions. Don’t leave labels loaded in the printer
between jobs; they curl around the platen and may jam
when you resume printing.
Envelopes
You can feed envelopes individually using the single-sheet loading
feature. Before loading envelopes, adjust the position of the paper
thickness lever. See The Paper Thickness Lever earlier in this
chapter.
2-28
Paper Handling
When manually feeding an envelope, you may have to push it down
slightly while pressing the LOAD/EJECT button to get it to feed
properly.
CAUTION: The printable area for envelopes is shown on
the next page. The print head must not go past the left or
right edge of the envelope or other thick paper. Make sure
that the page setup of your application program keeps the
printing entirely within this printable area.

Other Control Panel Features
The control panel of your printer also gives you access to several
special functions.
Self test:
Both a draft and Letter Quality self test function
are built into the printer. The self test printout
lets you check the current DIP switch settings
and operating status of the printer. You can
start the printer's self test by holding down the
LINE FEED button or the FORM FEED button while
turning on the printer. See Testing the Printer in
Chapter 1 for more information.
Micro-adjustment: By pressing the FORM FEED button immediately
after loading paper or when using short tear-off,
you can make fine adjustments to the loading
and short tear-off positions. These positions can
only be adjusted while the MULTI-PART light is
blinking. See Adjusting the Loading Position and

Selecting Typestyles
You can produce a wide range of typestyles by selecting different
character fonts, widths, and other enhancements from the SelecType
control panel or by using software commands. This section describes
only the features controlled by SelecType. To use software
commands, see the Command Summary in Chapter 9.
You can use the SelecType section of the control panel to choose
fonts and condensed printing. Orange lights indicate which features
you have chosen.
Note: The settings you select using the SelecType panel remain
valid even after you turn off, reset, or initialize the printer.
However, commands from your application program temporarily
override the SelecType settings.
Some application programs are designed to control all typestyle
functions. These programs cancel all previous typestyle settings
with software commands. Because these commands override
SelecType settings, you should use the program’s print options
instead of SelecType to select your typestyles. If SelecType does
not work with a particular application, check your software
manual for instructions on selecting typestyles.
Character Fonts
Your printer has ten built-in fonts: draft, Epson Roman, Epson Sans
Serif, Epson Courier, Epson Prestige, Epson Script, OCR-A, OCR-B,
Epson Orator, and Epson Orator-S. Eight of the fonts are selectable

The draft mode uses fewer dots per character for high-speed
printing, which makes it ideal for rough drafts and editing work.
The other fonts are Letter Quality (LQ) fonts. Letter Quality takes a
little longer to print, but produces nicely formed characters suitable
for most documentation requirements.
Condensed Mode
You can use the condensed mode to change the size of printed
characters. In the condensed mode, characters are approximately 60
percent of the width of normal characters. Hence, condensed
printing is very useful for spreadsheets and other applications where
you need to print the maximum amount of information on a page.
You can combine the condensed mode with 10 cpi, 12 cpi, and
proportional printing, but not 15 cpi.
To select the condensed mode, simply press the CONDENSED button
so that the orange indicator light comes on. To turn off the
condensed mode, press the button again.
The following printout compares normal 10 and 12 cpi with

above the control panel. By changing the settings of these switches,
you can control various printer features, such as the character set
and page length. The new settings become effective when the printer
is turned on, reset, or initialized.
DIP switch settings are shown in the DIP switch tables later in this
section. Descriptions of all the DIP switch functions follow the
tables.
Changing a DIP Switch Setting
To change a DIP switch setting, follow these steps:
1. Turn off the printer.
2. Open the DIP switch cover and use a pointed object, such as a
pen, to change the DIP switch settings. A DIP switch is on when
it is up, and off when it is down.
The new DIP switch settings take effect when the printer is turned on.

The DIP Switch Functions
Auto line feed
When auto line feed is on (DIP switch 2-4 on), each carriage return
code (CR) is automatically followed by a line feed code (LF).
Input buffer capacity
The input buffer stores data from your computer. If you want to free
your computer for other tasks while the printer prints, change the
setting of switch 2-5 to 8 KB (on). Before using user-defined
characters, however, be sure to set the input buffer to 1 KB (off).
Printing direction
With unidirectional printing, the print head prints in one direction
only. This allows for precise vertical alignment, making it ideal for
printing graphics such as lines and boxes. With bidirectional
printing, the print head prints in both directions. This is faster than
unidirectional printing.
When DIP switch 2-6 is off, the printer prints unidirectionally; when
it is on, the printer prints bidirectionally. Either setting can be
overridden by a software command (ESC U).
To achieve precise vertical alignment without the slower printing
speed caused by unidirectional printing, see your dealer for
adjustment of your bidirectional print settings.
Tear-off mode
When DIP switch 2-2 is on, the short tear-off mode is on. This feature
automatically advances continuous paper to the tear-off position,
and then reverse-feeds the paper to the loading position. See Using
Short Tear-off later in this chapter.
CAUTION: Do not use the short tear-off mode with labels.

Note: If you are using the cut sheet feeder, the page length is
automatically set when you run the self test. See The Cut Sheet
Feeder in Chapter 5 for details.

Skip Over Perforation
By changing the setting of DIP switch 2-3, you can set skip over
perforation to on or off. If this feature is on when using continuous
paper, a one-inch margin is provided between the last printable line
on one page and the first printable line on the next page. This feature
is very convenient if your application program does not provide for
top and bottom margins.
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 in the following illustration.

Note: Most application programs take care of top and bottom
margins. Use skip over perforation only if your program does not
provide these margins.
The skip over perforation setting can be set to values other than
one inch by using the ESC N command. See the Command
Summary in Chapter 9 for details.
3-16
Using the Printer
Adjusting the Loading Position
The loading position is the position of the paper when it has been
automatically loaded by the printer.
This position is important because it determines where the printing
begins on the page. If the printing is too high or too low on the page,
change the loading position using the micro-adjustment feature
described in the next section.
CAUTION: Never use the platen knob to feed paper except
in case of a paper jam or other paper feeding problem. (If
you need to use the platen knob, make sure the power is
off.) If you need to adjust the loading position, always use
the micro-adjustment feature.
Until the loading position is reset, the printer remembers this
position even if it is turned off, and uses it as a reference point for
feeding paper.
The micro-adjustment feature moves the paper in 1/180-inch
increments to make fine adjustments to the loading position. Once
you have used micro-adjustment to change the loading position of
continuous paper, the printer remembers that position even after it is
turned off.
When you use micro-adjustment to change the loading position of
single-sheet paper, however, the printer does not remember this
position after the power is turned off. When the power is turned
back on, the loading position returns to its factory setting.
Using Micro-adjustment
1. Make sure that the printer is turned on and that either a single
sheet or continuous paper is loaded.
Using the Printer
3-17
2. Press the ON LINE button. The MULTI-PART light begins to blink.
MULTIPART
Note: You can use the FORM FEED and LINE FEED buttons for
micro-adjustment only while the MULTI-PART light is blinking.
3. Press the FORM FEED button to feed the paper forward or the
LINE FEED button to feed the paper backward.
Note: When the paper reaches the factory-set loading position,
the printer beeps and micro-adjustment feeding pauses for a
moment before continuing. You can use this factory setting as
a reference point when adjusting the printer’s loading
position. When the paper reaches either the minimum or
maximum top margin, the printer beeps and the paper stops
moving.
3-18
Using the Printer
Using 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 printer cover so that you can tear off the last
sheet. When you resume printing, the paper feeds backward to the
loading position. This feature lets you save the paper normally lost
between documents.
To use this feature, set DIP switch 2-2 to on. Then load continuous
paper in the normal way.
You can leave the short tear-off feature turned on (DIP switch 2-2 on)
even when you are using single sheets. When you move the paper
release lever to the singlesheet position, the short tear-off feature is
disabled.
CAUTION: Never use short tear-off with labels.
Otherwise, labels may come off their backing and jam the
printer.
When you have finished printing, and if the perforation is at the top
of form position, the printer automatically feeds the perforation of
the continuous paper to the tear-off edge of the printer cover. You
can then tear off the page using the tear-off edge as shown on the
next page.
Using the Printer
3-19
If the page perforation is not properly aligned with the tear-off edge,
you can adjust the tear-off position using micro-adjustment, as
described below.
Note: Short tear-off is performed whenever the printer receives a
full page of data or a form feed, and no more data is received for
three seconds.
When you resume printing after tearing off the sheet, the paper
automatically feeds backward to the loading position before printing
begins.
Adjusting the Tear-off Position
If the paper’s perforation does not meet the tear-off edge, follow
these steps to adjust the tear-off position.
1. Make sure the printer feeds the paper to the tear-off position
after printing the document.
3-20
Using the Printer
2. The MULTI-PART light should begin blinking, indicating that you
can now use the micro-adjustment feature to make fine
adjustments to the tear-off position.
3. To make fine adjustments to the tear-off position, press the
FORM FEED button to feed the paper forward or the LINE FEED
button to feed it backward.
You can now tear off your document from the perforation and
resume printing. The printer remembers this new tear-off position
even after the printer is turned off.
Using the Printer
3-21
Selecting an International Character Set
International character sets provide you with the characters and
symbols used in other languages. You can select one of eight
international character sets by changing the DIP switch settings.
Whenever the printer is turned on, reset, or initialized, the character
set selected by the DIP switches becomes the default character set.
To select an international character set, set DIP switches 1-1,1-2, and
1-3 according to the table below.
Note: DIP switch 1-7 must be off. To select an international
character set when DIP switch 1-7 is on, use the ESC R command.

Choosing a Character Set
DIP switch 1-7 selects either the italic character set or a graphics
character set. The graphics character sets contain international
accented characters, Greek characters, mathematic symbols, and
character graphics for printing lines, corners, and shaded areas.
®
If you have an IBM or IBM-compatible computer, select a graphics
character set when you wish to print character graphics as they are
displayed on the screen. Even if you select a graphics character set,
you can still print ordinary text and italics. For italics, see your
software manual or the description of the ESC 4 command in the
Command Summary, Chapter 9.
Note: In most cases, a graphics character set is the preferred
selection.
To select either the italics or a graphics character set, set DIP switch
1-7 according to the table below.

experienced users to identify the cause of communication problems
between the printer and application programs. The data dump mode
gives a printout of the codes reaching the printer.
To use the data dump mode, follow these steps:
1. Make sure the printer is loaded with either single sheet or
continuous paper.
Note: Use paper at least 7.2 inches (182 mm) wide.
2. If the printer is on, switch it off, then hold down the FORM FEED
and LINE FEED buttons at the same time you turn on the printer.

Enhancing Your Printing
You can obtain a wide variety of printing effects with your printer,
from changing the number of characters per inch to using special
effects on selected words and phrases. This section gives you a
sampling of the features you may select with your software.
For software control of these features, see the instructions for your
application programs or look up their specific commands in the
Command Summary in Chapter 9.
Character Spacing
To add greater variety to your documents, the printer has three cpi
spacings, as well as proportional spacing. Each one can be selected
with a software command.
For each of the built-in fonts, you can choose a character spacing of
10, 12, or 15 characters per inch, or proportional spacing. The
printout below compares the three spacings:
This is 10 cpi printing.
This is 12 cpi printing.
This is 15 cpi printing.
As shown above, 15 cpi characters are only about two-thirds the
height of 10 and 12 cpi characters. This makes 15 cpi particularly
useful when you want to separate certain material from the main
text.
In fixed cpi spacing each character is given the same amount of
space. The width of proportional characters, however, varies from
character to character. For example, a narrow letter like i takes less
space than a wide letter like W. The width of each proportional
character is given in the Appendix.
4-2
Software and Graphics
The following printout compares 10 cpi spacing with proportional
spacing:
This is 10 cpi printing.
This is proportional printing.
Note: Proportional spacing is not available in the draft mode.
See the Print Size and Character Width commands in Chapter 9.
Character Size
In addition to the basic cpi spacings and proportional spacing, the
printer offers three other modes that can change the size of your
printing. These modes are double-width, double-height, and
condensed.
The doublewidth mode doubles the width of any size character,
while the double-height mode doubles the height of any size
character. These modes are useful for emphasizing document titles
and headings in reports, but are usually not suitable for large
amounts of text. These modes can also be combined to obtain even
more impressive printing results.
This is normal 10 cpi printing.

Software and Graphics
4-3
Enhancing Your Printing
Both 10 and 12 cpi printing can be reduced to about 60 percent of
their normal width using the condensed mode. This mode is
particularly useful for printing wide spreadsheets because
condensed 12 cpi printing allows you to print up to 160 characters
on an 8-inch line.
The condensed mode can be selected with a software command, or
by using SelecType (see Chapter 3). Even if you turn the condensed
mode on with SelecType, you can still turn it off with a software
command.
Condensed 10 cpi gives you many characters on a line,
Condensed 12 cpi gives you even more characters on a line.
Widening or narrowing the characters also widens or narrows the
spaces between words. Because word processors usually create a left
margin by printing spaces, you may need to change the left margin
and the number of characters on a line to keep the margins correct if
you change character widths.
See the Print Size and Character Width commands in Chapter 9.
Special Effects and Emphasis
The printer offers two ways of emphasizing text and also allows you
to use underlining, superscripts, subscripts, and italics. These
features can be controlled directly by software commands. Many
application programs can also produce some of these effects. See
your application program manual for details.
Emphasized and double-strike printing
Emphasized and double-strike printing can give words and phrases
added prominence. In emphasized mode, each character is printed
twice as the print head moves across the paper, with the dots in the
second pass printed slightly to the right of the first pass. This process
produces darker, more fully formed characters.
4-4
Software and Graphics
Enhancing Your Printing
In double-strike mode, the print head prints each line twice, making
the text bolder. For even greater boldness, emphasized and doublestrike can be combined. The following samples show the different
effects you can achieve using these modes alone and in combination.

Underlining, strike-through, and overlining
The underline, strike-through, and overline modes are useful for
highlighting selected text. This feature can be used to score spaces,
subscripts, and superscripts without a break. You can choose from a
variety of line styles, including single, double, broken, or
continuous. See the ESC (-command in Chapter 9 for more
information.

Software and Graphics
Graphics
The dot graphics mode allows your printer to produce pictures,
graphs, charts, or almost any other pictorial image you can create.
The quickest and easiest way to print graphics on your printer is to
use a commercial graphics program. With such programs 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.
If you use commercial software that produces graphics, all you need
to know about dot graphics is how to use the software. The
application program will take care of the printer. (Some programs
call this bit image printing.) On the other hand, if you wish to do
your own programming or merely wish to understand how this
printer prints graphics, read on.
Software and Graphics
4-7
The Print Head
To understand dot graphics you need to know a little about how
your printer's print head works.
The print head has 24 pins. As the print head 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 producing a
small dot. As the print head moves along, the pins fire time after
time in different patterns forming letters, numbers, and symbols.
Because the dots overlap each other both horizontally and vertically
in Letter Quality mode, it is difficult to see the individual dots.
Instead, the letters and symbols seem to be made up of unbroken
lines.
In order for the dots to overlap vertically, the pins in the print head
are in more than one column, but the intelligence of the printer
handles the timing of pin firings so that the effect is that of 24 pins
arranged in a single vertical column.
Dot patterns
The print head is able to print graphics, as well as text because
graphic images are formed on the printer in about the same way that
pictures in newspapers and magazines are printed. If you look
4-8
Software and Graphics
closely at a newspaper photograph, you will find that it is made up
of thousands of small dots. Your printer also forms its images with
patterns of dots, as many as 360 dots per inch horizontally and 360
dots per inch vertically. The images printed by this printer can,
therefore, be as finely detailed as the ones at the beginning of this

The graphics mode that takes full advantage of this printer’s print
head is 24-pin graphics. This mode has five densities, but for
simplicity this explanation deals with only one of them, tripledensity.
Triple-density prints up to 180 dots per inch horizontally. As the
print head moves across the paper, every 1/180th of an inch it must
receive instructions about which of its 24 pins to fire. At each
position it can fire any number of pins, from none to 24. This means
that the printer must receive 24 bits of information for each column it
prints. Because the printer uses 8-bit bytes of information in
communicating with the computer, it needs three bytes of
information for each position.
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. Because 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.

To fire any one pin, you send its number to the printer. To fire more
than one pin at the same time, add up the numbers of the pins and
send the total. Using these labels for the pins, you fire the top pin by
sending 128. To fire the bottom pin, you send 1. If you want to fire
only the top and bottom pins, you simply add 128 and 1, and send
129.
By adding the appropriate label numbers together, you can fire any
combination of pins. Below are three examples of how to calculate
the number that will fire a particular pattern of pins.

With this numbering system, any combination of the eight pins adds
up to a decimal number between 0 and 255, and no numbers are
duplicated.
Because 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 graphics
software is available to do these calculations for you.
Before you can put these numbers into a graphics program,
however, you need to know the format of the graphics command.

Software and Graphics
The Graphics Command
The graphics mode command is quite different from the other
commands used by the printer. For most of the other printer modes,
such as emphasized and double-width, one ESC code turns the
mode on and another turns it off. For graphics, the command is more
complicated because the code that turns on a graphics mode also
specifies how many columns it will use. After the printer receives
this code, it interprets the numbers that follow as pin patterns and
prints them on the paper.
Your printer has one command that allows you to use any of the 11
graphics options. The format of the command is:
ESC* m n1 n2 data
In this command, m selects the graphics option and n1 and n2
specify the number of columns to reserve for graphics. The available
graphics options are listed below.

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 printer does not use numbers larger than 255 in
decimal. Therefore the graphics mode command uses two numbers,
n1 and n2, for reserving columns.
To find n1 and n2, divide the total number of columns by 256. The
result is n2; the remainder is n1. Because the command is set up for
two numbers, you must supply two even if you need only one.
When you need fewer than 256 columns, just make n1 the number of
columns you are reserving and make n2 a zero.
For example, if you wish to send 1632 columns of graphics data, n1
should be 96 and n2 should be 6 because 1632 = 96 + (6 x 256).
The printer interprets the number of bytes specified by n1 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 printer
stops and waits for more data and seems to be locked. If, on the
other hand, you supply too much graphics data, the excess is
interpreted and printed as regular text.
A Simple Graphics Program
This first program is just a simple example to show you how the
graphics command, column reservation numbers, and data can be
used in a BASIC program.

Line 20 selects single-density 24-pin graphics mode (mode 32) and
also reserves 40 columns for graphics. Because 24-pin graphics
requires three bytes of data for each column, line 30 begins a loop to
supply 120 bytes of data. Line 40 contains the number 170, which
produces the first pin pattern shown in the section on pin labels, and
line 50 ends the loop.
Designing Your Own Graphics
With what you know now, you can use the simplest application of
graphics—calculating by hand the data to print the graphic image.
While this method is the most tedious, it helps you understand dot
graphics. It is also useful for small graphic elements that are used
many times.
Software and Graphics
4-13
The illustration below shows how you can use a grid on paper to
plan where you want dots to be printed. This grid is for a single line
of graphics 42 columns long. Because each line of 24-pin graphics is
approximately 1/8th of an inch high and because triple-density
graphics prints 180 dots per inch horizontally, a design planned on
this grid will be about 1/8th of an inch high and less than 1/4th of
an inch wide.
The actual pattern that the printer prints on the paper is, of course,
made up of dots that overlap each other both vertically and
horizontally. The reason the planning grid uses an x for each dot is
that using an accurate representation of the dots makes calculating
the data numbers difficult because they cover each other. Therefore,
remember that each x represents the center of a dot, and the dots
actually overlap.
Write the assigned values of the pins next to your design, then total
the values for each column of dots. These totals are the values that
you send to the printer as graphics data to print the design.

Below is the same grid divided into three sections to make the data
calculation easier. At the bottom of each section of each column is
the total of the pin numbers for that section. This gives you the total

Lines 80 through 140 contain 126 bytes of data (42-pin columns x 3
bytes) for each pin column. Lines 30 through 60 print the design that
you see below.
Notice that the dots overlap quite a bit. This design was printed
using the triple-density, 24-pin graphics option because the density
is the same (180 dots per inch) in both directions.
Adding the following lines to the preceding program causes the
pattern to print 10 times in a row as shown below.

User-defined Characters
With this printer, it is possible to define and print characters of your
own design. You can design an entirely new alphabet or typeface,
create special characters for use 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.
Note: To use user-defined characters, you must turn DIP switch
2-5 off.
You can make the task of defining characters easier by using a
commercial software program that assists you in creating characters
or simply supplies you with sets of characters already created. Also,
some popular software programs make use of the printer’s userdefined character function to enhance printouts. (These characters
are called download characters in some programs.)
The standard ASCII characters are stored in the printer’s Read Only
Memory (ROM), and the user-defined characters are stored in the
printer’s Random Access Memory (RAM).
Designing Your Characters
User-defined characters are like dot graphics because you send the
printer precise instructions on where you want each dot printed. In
fact, planning a user-defined character is like planning a small dot
graphics pattern.
Software and Graphics4-17
Design grids
To design a character you use a grid that is 24 dots high—one dot for
each pin on the printer’s print head. The width of the character
matrix depends on 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. The dots for both Letter
Quality and proportional characters are spaced more closely
together than those for draft characters.
The illustrations below show the two design grids. The line at the
side, labeled cap height, indicates the top of a standard capital letter.
The line labeled baseline indicates the baseline for all letters except
those with descenders (the bottom parts of such letters as j and y).
The bottom row is usually left blank because it is needed for
underlining.
Draft pica
Letter quality / Proportional
The grid on the right side can be used for either Letter Quality or
proportional characters. For Letter Quality you do not use all the
columns.
4-18
Software and Graphics
User-defined Characters
There is one restriction in designing characters. Dots in the same row
may not print in adjacent columns. This means that there must be an
empty dot position both to the left and right of each dot that prints.
This is true in draft, Letter Quality, and proportional mode.
Defining Your Characters
The first step in defining characters is to place the dots on a grid just
as you want them to print. The examples shown 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 userdefined character planned on it.
Now you translate the dot pattern you’ve created on paper to a
numeric format so you can send the data to your printer. Every dot
has an assigned value. Each vertical column (which has a maximum
of 24 dots) is first divided into three groups of eight dots. Each group
of eight dots is represented by one byte, which consists of eight bits.
Hence, one bit represents one dot.
Software and Graphics
4-19
User-defined Characters
Data numbers
The bits within each byte have values of 1,2,4,8,16,32,64, and 128.
In the vertical column of dots, the bits are arranged so that the most
significant bit (with a value of 128) is at the top of the column and
the least significant bit (with a value of 1) is at the bottom.
The next illustration shows how to use this method to calculate the
data numbers for the character in this example. 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
in which dots appear. The right side of the figure shows the whole
character with the three data numbers for each column indicated at
the bottom.
This manual uses decimal numbers because the program examples
are written in BASIC and everyone is familiar with decimals. The
data you send to your printer, however, must be in the form (binary,
decimal, hexadecimal) that you can use with your programming
language.
4-20
Software and Graphics
User-defined Characters
You have seen how to design a character by placing dots on a grid
and translating the dots to decimal equivalents. The last step in
defining a character is sending this information to your printer.
Sending Information to Your Printer
The printer loads characters in the print style (Letter Quality, draft,
or proportional) that the printer is currently using. It also records
whether italic, superscript, or subscript is turned on. This means that
if you want to print a character in italics, for example, you must have
the italic mode turned on when you define the character.
The command your printer uses to define characters is one of the
most complex in its repertoire. The format of the command is this:
ESC & 0 n1 n2 d0 d1 d2 data
The ESC & is simple enough. The 0 allows for future enhancements.
At this time, it is always ASCII 0.
You can define many characters with a single command. The values
n1 and n2 are the ASCII codes of the first and last characters you are
defining. If you are defining only one character, n1 and n2 are the
same. You can use any codes between decimal 32 and 127 for n1 and
n2, but it is best not to define decimal 32, which is the code for a
space. Also, you can use letters in quotation marks instead of ASCII
codes for n1 and n2.
Note: Because user-defined characters require additional memory,
you must set DIP switch 2-5 to 1 KB (off) before downloading
these characters.
Software and Graphics
4-21
User-defined Characters
An example will show how to specify n1 and n2. For instance, if you
wanted to redefine the characters A through Z, n1 would be ASCII A
(or decimal code 65) and n2 would be ASCII Z (or decimal code 90).
So the command ESC & 0 AZ (followed by the appropriate data)
would replace the entire alphabet of capital letters.
Following the specification of the range of characters to be defined in
this command are three data bytes, d0, d1, and d2, that specify the
width of the character and the space around it. The left space (in dot
columns) is specified by d0, and the right space is specified by d2.
The second byte, d1, specifies the number of columns of dots that are
printed to make up the character. By varying the width of the
character and the spaces around it, you can create proportional
width characters that print at draft speed. The table below shows the
maximum values for these bytes.

The last part of the command to define your characters is the actual
data that defines the dot patterns for each character. Because it takes
three bytes to specify all the dots in one vertical column, your printer
expects d1 x 3 bytes of data to follow d2.

150 DATA 8,0,0,23,255,240,8,0,0
160 DATA 4,0,0,2,0,0,1,0,0
In line 10, the ESC x0 command selects draft printing.
The actual character definition starts in line 20. The two @ signs in
line 30 represent n1 and n2, the range of characters being defined (in
this case, a range of 1). Line 40 contains d0, d1, and d2.
The information about the actual character design (which is
contained in the DATA statements at the end of the program) is sent
to the printer in the loop between lines 50 and 70.
Note: When defining Letter Quality or proportional characters,
put a WIDTH statement in your program to prevent carriage
return and line feed codes from interfering with your definitions.
Software and Graphics
4-23
User-defined Characters
Printing User-defined Characters
If you entered the previous program example, you defined an arrow
and placed it in the RAM location for ASCII code 64 (replacing the @
sign). You can now print out a three-line sample of your work. The
first and third lines (printed by lines 80 and 120) print the normal @
sign. The second line (printed by line 100) prints out the arrow that
you defined.
Run the program to see the printout below.
As you can see, both sets of characters (the @ from the original
characters in ROM that the printer normally uses and the alternative
character you defined) remain in the printer available for your use.
The command to switch between the two sets is used in line 90 and
110. It is:
ESC % n
If n is equal to 0, the normal ROM character set is selected (this is the
default). If n is equal to 1, the user-defined character set is selected. If
you select the user-defined character set before you have defined
any characters, the command is ignored and the ROM characters
remain in use.
You may switch between character sets at any time--even in the
middle of a line. To try this, place semicolons at the end of lines 80
and 100 in the program example.
4-24
Software and Graphics
User-defined Characters
Copying ROM Characters to RAM
After running the program, if you select the user-defined character
set and try to print other characters, the only one that will print is
your arrow. Because no other characters are in the printer’s userdefined RAM, there is nothing else to print. Other characters sent to
the printer do not even print as spaces; it’s as if they were not sent at
all.
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 your user-defined character
set. It is, however, rather inconvenient.
Therefore, your printer has a command that allows you to copy all of
the standard characters from ROM to the user-defined character set.
The command format is as follows, where the value of n represents
the font family:
Esc: 0 n 0
Note: This command cancels any user-defined characters you
have already created. You must send this command to the printer
before you define characters.
If you use this command at the beginning of a program, then define
your special characters and select the user-defined set, you can print
with the user-defined set as your normal character set. You never
need to switch back and forth between sets.
Software and Graphics
4-25
Letter Quality Characters
If you select Letter Quality printing with the ESC x1 command, you
can design user-defined characters using up to 29 columns of the
Letter Quality/Proportional grid. The dot columns are spaced closer
together horizontally than draft dot columns (the horizontal dot
spacing is 1/360th of an inch as opposed to 1/120th of an inch for
draft characters).
Proportional mode characters
Selecting the proportional character mode yields user-defined
characters of the highest resolution. Characters can be designed
using all 37 columns of the Letter Quality/Proportional grid.
Remember that in Letter Quality and proportional modes, as in draft
mode, you cannot place dots in adjacent columns. There must be an
empty dot position both to the left and right of each dot that prints.
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, superscript and subscript characters
are created when either superscript or subscript is selected.
These characters can be used as either superscripts or subscripts. The
characters are exactly the same; only their placement is different. The
difference between these characters and regular characters is that
superscript and subscript characters are smaller. They are a
maximum of 16 dots high. Their maximum width in dot columns is
shown in the table below.

Because superscript and subscript characters are smaller, when you
define them you only need two bytes of data for each vertical row of
dots. Design grids for these characters are shown in the figure below.

Mixing Print Styles
Each of the three user-defined character modes (draft, Letter Quality,
and proportional) can be used in combination with most of your
printer’s various print styles. For instance, emphasized mode works
with user-defined characters. The characters you design are
enhanced to give this printing effect.
Mixing the three types of user-defined character sets is not possible.
For example, if you select draft and define some characters, then
select proportional and define some more, the first draft character
definitions are deleted. Only one type of character definition may be
stored in RAM at any time.
If you define characters in one mode, then switch to another mode
and select the user-defined character set, the command is ignored
and nothing is printed. The user-defined character definitions,
however, remain unaffected. If you switch back to the mode in
which they were defined, you can then select and print them.
Software and Graphics
4-27
Keep in mind that user-defined characters are stored in RAM, which
is not permanent memory. When the printer power is turned off or
the printer is initialized with the INIT signal, the user-defined
characters are lost. (Some computers do this each time BASIC is
loaded.)

Testing the Printer in the Cut Sheet Feeder Mode
When you perform the cut sheet feeder self test, the printer counts
the number of lines on the page. As shown on the following page,
the number of lines counted is printed out at the bottom of the first
test page. This number is the default page-length setting. This
setting, however, can be overridden by software commands.
Running the self test is the same as when the cut sheet feeder mode
is off. The steps below are for a self test in draft mode.
Note: Run the self test using paper that is 8¼ inches (210 mm)
wide on the standard width printer and 14 inches (360 mm) wide
on the wide carriage printer.

The Interface Boards
A number of optional interfaces are available that supplement the
capabilities of your printer’s built-in parallel interface.
Choosing an Interface
Optional interfaces can be divided into four main categories which
are described briefly below.
Serial interfaces are required if your computer is not equipped
with a parallel interface or if you need an interface that conforms
to the Current Loop standard instead of RS-232C. These
interfaces also provide some combination of the following
features: X-ON/X-OFF data communication protocol, loopback
self test modes, and data buffers that increase the printer’s data
buffering capacity by 8 KB.
IEEE-488 interfaces offer standardized connections, trouble-free
operation, and the ability to connect computers, printers, and
other devices on the same line so that they may share data freely.
Third-party interfaces, such as Coax and Twinax, allow Epson
printers to function as local IBM printers without the addition of
any other circuitry or components.
The buffered parallel interfaces also offer trouble-free operation
and standardized connections. They provide the printer with
more memory to free the computer for other tasks when printing
large amounts of text or graphics. You can increase the printer’s
data buffering capacity by an additional 32 KB (about 10 pages).
If you are not sure whether you need an optional interface or would
like to know more about interfaces, contact your dealer or call the
Consumer Information number listed in Where to Get Help.
Using the Printer Options
5-37
Compatible Interfaces
The following is a list of Epson interfaces that are compatible with
your printer.

intelligent IEEE-488 interface
C823032
32KB buffered parallel interface expandable to 512KB
C823021
32KB buffered serial interface expandable to 512KB
All Epson interfaces have the Epson name printed on them. If the
board has an identification code printed on it, it is a four-digit
number beginning with 8 and should correspond to one of the
numbers listed in the table above.
Coax and Twinax interfaces are also available from Epson dealers.
These interfaces allow connectivity to mainframe and
minicomputers and emulation of IBM printers.
Installation
The optional interface boards available for your printer are easy to
install. The only tool needed is a cross head screwdriver.
1. Turn off the printer. Then unplug the printer and remove the
printer cover and paper guide.
5-38
Using the Printer Options
WARNING: High voltages are present inside the printer
when the power is on. Do not attempt to remove the upper
case unless the printer is turned off and the power cord is
unplugged. Also, try not to touch contacts on the circuit
board of the printer because many of the components can
be destroyed by the static electricity present in your body.
Do not change the settings of any DIP switches on the
main board.
2. Remove the screw securing the interface board cover and lift off
the cover.

subject it to excessive bending.
2. Reattach the board cover.
CAUTION: When an optional interface board is installed,
be sure to disconnect the printer cable from the printer’s
built-in parallel interface. Two interface cables must not be
connected at the same time.
Using the Printer Options
5-45
#8143 New Serial Interface
If you are using an optional interface, it may be necessary for you to
alter the communication protocol of the printer or the computer so
that they can communicate properly. In most cases, you should use
the information in your optional interface manual or your
computer’s manual to match the computer with the interface.
If you are using the #8143 optional interface board, make sure that
you read through the section below on baud rate selection. You may
also want to see the sections on handshaking timing and error
handling for interface information specific to your printer.
For all other data transfer conventions, such as word structure or
communications protocol, use the information in the manual
supplied with your #8143 optional interface.
Baud rate selection
You can select baud rates from 75 to 19,200 BPS (Bits Per Second).
When setting the baud rate, make sure you use the bit rate selection
table for printers with buffers (in the #8143 interface manual).
For more information on the printer’s input buffer settings, see
Setting the DIP Switches in Chapter 3 of this manual.
Handshaking timing
When the vacant area for data in the input buffer drops to 256 bytes,
the printer outputs an X-OFF code or sets the DTR flag to 1 (MARK)
indicating that it cannot receive data.
Error handling
When a parity error is detected, your printer prints an asterisk (*).
All other errors, including framing and overnm, are ignored.

Set DIP switch 2-4 on so the printer automatically adds a line
feed code to each carriage return.
l
The text is printed with an extra blank line in between.
Two line feed signals are being sent. Set DIP switch 2-4 off.
l
Page length does not match the length of the paper.
Check the page length set by DIP switches 1-4 and 1-5.
Check the page length set by your application software and
adjust it if necessary.
l
Regular gaps occur in the printout.
One-inch skip over perforation may be set. Set DIP switch 2-3 to
off.
l
Skip over perforation is set, but the perforation does not fall in the
center of the skip.
Adjust the loading position.
Troubleshooting 7-5
l
Vertical printed lines do not align or gaps appear in lines or graphics.
The printer is usually set for bidirectional printing. This can
cause a slight misalignment of graphics characters. When precise
printing of vertical lines is necessary, contact your dealer to have
the bidirectional print alignment adjustment performed.
You can also select unidirectional printing by setting DIP switch
2-6 to off. Unidirectional printing is slightly slower.
If the printer still does not print, disconnect the printer from your
computer and try the self test described in Chapter 1. If the self test
works properly, the printer is working, and the problem probably
lies in the computer, the software, or the cable. If the self test does
not work or if any other problem persists, contact your dealer or call
the Consumer Information number listed in Where to Get Help.
7-6 Troubleshooting
Paper Handling
The following section guides you through problems in handling
single sheets of paper and continuous paper. If you are having
problems using the optional cut-sheet feeder or pull tractor, see
Options later in this chapter.
Single sheets do not feed properly.
l
Paper was inserted in the sheet guide, but the platen did not move and
paper was not fed.
The left edge guide may be set too far to the right so that the
paper detector cannot sense it. Move the paper a little to the left.
The PAPER OUT light should go off.
l
Paper was inserted in the sheet guide, and the platen rotated, but paper
was not fed.
Check that the paper release lever is pushed back to the single
sheet position.
Check that the paper guide is installed properly.
The left and right edge guides may be too close together,
preventing the paper from feeding smoothly. Adjust the position
of the edge guides so that the paper can move up and down
freely.
The paper may not be firmly inserted. When feeding thicker than
normal paper, press down lightly on the paper.
Troubleshooting 7-7
l
Paper loads, but then jams.
The cut sheet feeder mode may be turned on (DIP switch 1-8 is
on). When the cut sheet feeder is not in use, DIP switch 1-8
should be off.
The edge guides may be too far apart. Adjust the edge guides to
the width of the paper.
The dimensions of the paper may exceed the specified
limitations. Use only paper sizes that are within the specified
range. Multi-part forms cannot be used with this printer’s single
sheet feeding system.
Continuous paper does not feed properly.
l
When the LOAD/EJECT button is pressed, the platen does not rotate and
paper does not feed.
You may be trying to feed paper using the control panel buttons
while the printer is on line (ON LINE light on). Press the ON LINE
button once to set the printer off line; then try feeding paper.
After feeding paper, press the ON LINE button again to set the
printer on line.
The paper release lever may be pushed back to the single sheet
position. When using the tractor, be sure the paper release lever
is pulled forward to the continuous paper position.
On the wide carriage printer, the paper release lever must be in
the center position when using the built-in push tractor, and it
must be in the forward position when using the optional pull
tractor.
l
When the LOAD/EJECT button is pressed, the platen rotates but paper
does not feed.
Continuous paper may have already been in the paper path. (In
this case, the paper feeds backward to the standby position.)
Press the LOAD/EJECT button again to load the paper.
7-8
Troubleshooting
l
The paper feed is crooked or the paper jams.
Make sure the paper supply is not obstructed by a cable or some
other object, and that the paper feeds smoothly into the printer.
Check that the holes on the sides of the paper are aligned with
each other. Also, make sure the sprocket lock levers are locked
and the sprocket covers are closed.
l
The short tear-off function does not work.
Make sure DIP switch 2-2 is set to on.
Short tear-off is performed whenever the printer receives a full
page of data or a form feed and no more data is received for
three seconds. Make sure your software sends a form feed at the
end of a document.
Troubleshooting 7-9
Options
This section describes problems you may encounter while using the
optional cut sheet feeder or an optional interface board.
With the cut sheet feeder, paper does not feed properly.
l
When a print command is sent from the computer, the platen rotates,
but paper does not feed.
Make sure DIP switch 1-8 is on.
Make sure the cut sheet feeder is correctly installed on the
printer.
Check that the paper release lever is pushed back to the single
sheet position.
Make sure paper is loaded in the cut sheet feeder’s bin. If only
one sheet is left in the bin, add more paper.
l
Two or more sheets feed at the same time.
You may have loaded too many sheets in the cut sheet feeder’s
bin.
You may have forgotten to fan the stack of paper before loading
it into the bin. Remove the paper and fan it.
l
The paper feed is crooked.
The paper may be old or creased. Use only new, clean sheets of
paper.
Make sure that your paper is the proper size and quality.
l
One page of printing has spread to two pages.
Check that the page length setting is correct.
7-10
Troubleshooting
With an optional interface, the printer does not operate properly.
l
The printer does not print or the printout is not what you expected.
Check that the interface board is correctly inserted into the
connector on the main board.
Check the specifications to make sure that you can use the
interface with this printer.
Make sure that the cable matches the interface specifications.
Check that the DIP switches or jumpers on the interface board
are set correctly. Also, make sure that the computer and interface
settings match.

This level becomes LOW when the
printer is:
1) in paper out state.
2) off line.
3) in error state.
Pulled up to 5V through 3.3 Kohm
resistance.
The DC1/DC3 code is valid only when
this signal is HIGH. (Internal fixing can
be carried out with Jumper J10. The
level of this signal is factory-set to
LOW.)
The column heading “Direction” refers to the direction of signal
flow as viewed from the printer.
“Return” denotes the twisted-pair return, to be connected at
signal ground level. For the interface wiring, be sure to use a
twisted-pair cable for each signal and to complete the connection
on the return side. These cables should be shielded and
connected to the chassis of the host computer and the printer.
All interface conditions are based on TTL level. Both the rise and
the fall times of each signal must be less than 0.2 microseconds.
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.

Each command description has a format section and a comment
section. The format section gives the ASCII, decimal, and
hexadecimal values for the command. These three formats are
equivalent, and it should be easy to pick the one most suited to your
purpose. The comment section describes the effect of the command
and gives any additional information necessary for using it.
Note: Some application programs use control key sequences. See
the Control Key chart later in this chapter.
9-2 Command Summary
The simplest type of command consists of a single character to be
sent to the printer. For instance, to print in condensed mode, the
code format is:
ASCII code:
SI
Decimal:
15
Hexadecimal: OF
This code can be sent from a program by sending the code 15
directly.
More complex commands consist of two or more character codes.
For example, to print in double-wide mode, the code format is the
following:
ASCII
code:
Decimal:
Hexadecimal:
ESC
W
n
27
87
n
1B
57
n
In this case n can be either 1 (on) or 0 (off), to begin or end doublewidth printing. You can use either of the following commands to
turn on double-width print from BASIC:
LPRINT CHR$(27);CHR$(87);CHR$(1)
LPRINT CHR$(27);"W";CHR$(1)
For the following commands that use only 0 or 1 for the variable,
either the decimal or hexadecimal values 1 and 0 or the ASCII
characters 1 and 0 can be used:
ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, and ESC %
For example, in BASIC you can turn on proportional spacing with
either of these statements:
LPRINT CHR$(27);"p";CHR$(1)
LPRINT CHR$(27);"p";"1"
Command Summary 9-3
Control Key Chart
Some application programs 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 application programs that use this system cannot use
[email protected], and many programs use the control keys for other
purposes.

to the left, subtract it from 65536. Send the resulting number using
this formula: total number of dots = n1 + (256 x n2). The command
is ignored if it would move the print position outside the current
margins. A unit is 1/120th of an inch in draft, and 1/180th of an
inch in Letter Quality or proportional modes.

Proportional Width Table
This table lists the widths of your printer’s proportional characters.
The values given are in 360ths of an inch. (For example, a value of 36
is 36/360ths of an inch.) You may need to enter these widths into a
special table for your processing program so it can calculate the
number of proportional characters that will fit on a line.
The characters with no code indicated are international characters or
graphics. See the table in Chapter 3 for the relevant codes for the
international characters. Also, see the descriptions of the ESC R and
ESC t commands in Chapter 9 for information on how to use these
characters.
The following width table shows each character, its ASCII code
(hexadecimal), and its width. If there are two numbers in the width
column, the second one is for the superscript/subscript version of
the character.

Glossary
Note that these definitions apply specifically to printers. If a word is
italicized, see that topic for more information.
application program
A software program that helps you carry out a particular task, such
as word processing or financial planning.
ASCII
Acronym for the American Standard Code for Information
Interchange. A standardized coding system for assigning numerical
codes to letters and symbols.
auto line feed
When this feature is enabled using a DIP switch or external control
through the parallel connector, the printer will automatically feed
the paper one line after receiving a CR code.
baud rate
A measure of the speed of data transmission. Usually expressed in
bits per second or bps.
bidirectional printing
Printing in which the print head alternates printing a line left to right
then the next line right to left, and so on. Because the head prints in
both directions, the overall printing speed increases by eliminating
wasted (non-printing) movement.
binary
See number systems.
bit
A binary digit (0 or 1), which is the smallest unit of information used
by a printer or computer. See also number systems.
buffer
See input buffer and memory.
Glossary 1
byte
A unit of information consisting of eight bits.
carriage return (CR)
The control code that returns the print position to the left margin.
When issued together with a line feed, the print position moves to
the left margin of the next line. In bidirectional printing, the print
head may not physically move to the left margin.
character set
A collection of letters, numbers, and symbols that provides you with
the characters used in a particular language.
code page tables
See graphics character sets.
condensed
Printing in which each character is approximately 60 percent of the
width of standard characters. For example, condensed 10 characters
per inch (cpi) has 17 characters per inch. Useful for fitting wide
tables or spreadsheets onto the paper.
continuous paper
Paper which has sprocket-feed holes on both long edges, is
perforated between pages, and is supplied in a folded stack. Also
called fanfold paper.
control code
In addition to the codes for printable characters, the ASCII standard
also includes 33 other codes which are called control codes. These
control codes perform such functions as sounding the beeper and
performing a carriage return or line feed.
cut sheet feeder (CSF)
An optional, detachable device which automatically feeds single
sheets of paper into the printer.
2
Glossary
data dump
Sometimes called hex dump. A troubleshooting feature. When the
printer is in the data dump mode, each code that it receives is
printed in hexadecimal notation.
decimal
See number systems.
default
A value or setting that takes effect when the equipment is turned on,
reset, or initialized.
DIP switches
Small switches in a printer that control various printer functions and
set the default status of the printer when it is turned on or initialized.
DIP stands for Dual In-line Package.
dot graphics
A graphic design formed by patterns of dots. Also called bit image
graphics.
dot matrix
A method of printing in which each letter or symbol is formed by a
pattern (matrix) of individual dots.
double-height printing
Printing in which each character is twice as tall as normal.
double-strike printing
A way of producing bolder characters. Each character is printed
twice. Can only be used in draft mode.
double-width printing
A print width in which each character is twice as wide as normal
characters. (The cpi is halved.)
draft mode
One of two print qualities available on your printer. Draft uses fewer
dots per character for high-speed printing. See also Letter Quality.
Glossary 3
emphasized printing
A way of producing darker characters. In a single pass of the print
head, characters receive twice the number of dots.
ESC (escape) code
A special control code used to begin most printer commands.
ESC/P
Abbreviation for Epson Standard Code for Printers. The system of
commands lets you perform software control of your printer from
your computer. It is standard for all Epson printers and supported
by most application software for personal computers.
font
A font is a style of type designated by a family name.
form
In printer terminology, a form normally refers to a page.
form feed
Refers to both a control code and a panel button that advances the
paper to the top of the next page.
graphics character sets
The graphics character sets contain international accented characters,
Greek characters, and character graphics for printing lines, comers,
and shaded areas. Also called code page tables.
hexadecimal (hex)
See number systems.
initialize
To establish the initial default status of the printer by turning the
printer on or by sending an INIT signal or code.
input buffer
The memory in the printer in which data sent from the computer is
stored while waiting to be printed.
4 Glossary
interface
The means of connection between the computer and printer. See also
parallel interface and serial interface.
italic
A typestyle in which the characters slant. This sentence is italicized.
Letter Quality
One of two print qualities available on your printer. Letter Quality
provides better readability and appearance at a reduced print speed.
See also draft mode.
line feed
Both a control code and a panel button that advances the paper one
line space.
loading position
The position to which the paper is automatically loaded. It can be
adjusted by using the micro-adjustment feature.
memory
The printer, like a computer, has a memory. When you print a file
from a computer, the contents of the file are transferred quickly from
the computer’s memory to the printer’s memory. The printer then
prints information from its own memory at a much slower rate. This
way of printing frees the computer to do other work while the
printer is still working. The printer memory is sometimes called the
buffer memory or input buffer.
micro-adjustment
A feature that adjusts the paper loading and short tear-off positions
by the smallest possible increments.
Glossary 5
number systems
Three number systems are commonly used with printers:
binary is base 2 and uses only the digits 0 and 1. All information
in computer systems is handled in binary form represented by
electrical signals that are on or off. A binary digit is often called a
bit; any decimal number between 0 and 255 can be expressed by
an eight-bit binary number.
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.
on line
When the printer is on line, it is able to communicate with the
computer connected to it.
paper-out sensor
A small switch behind the platen that sends a signal when it is not in
contact with paper, informing the printer and remote computer that
there is no paper loaded, and causing the PAPER OUT light to go on.
paper tension unit
The part of the printer that fits above the platen to assure proper
paper tension in the printing area.
parallel interface
An interface that connects the computer and the printer. A parallel
interface transmits data one character or code at a time. See also
serial interface.
platen
The black roller that provides the backing for the paper during
printing.
6
Glossary
print quality
Your printer has two types of print quality; draft and Letter Quality.
Draft is for high-speed, draft quality jobs; Letter Quality is used to
produce more polished documents.
proportional printing
Printing in which the character width varies from character to
character. For example, a capital W receives much more space than a
lowercase i. The result looks more like a typeset book than a
typewritten draft.
pull tractor unit
An optional device that feeds continuous paper and multi-part
forms through the printer.
push tractor
A built-in device that feeds continuous paper through the printer.
RAM
Acronym for Random Access Memory. The portion of the printer’s
memory used as a buffer and as a place for storing user-defined
characters. All data stored in RAM is lost when the printer is turned
off.
reset
To return a printer to its defaults, either by a command, an INIT
signal, code, or by turning the printer off and on.
ROM
Acronym for Read Only Memory. The portion of the printer’s
memory used to store power-on instructions and built-in fonts.
self test
A method of checking the operation of the printer. When the self test
is run, the printer prints out its current DIP switch settings and the
characters that are stored in its ROM.
serial interface
A serial interface transmits data one bit at a time. See also parallel
interface.
Glossary 7
short tear-off
A feature that automatically feeds the perforation of continuous
paper to the tear-off position to be removed by the operator, and
then draws the paper back to the loading position. These positions
can be adjusted using the micro-adjustment feature. See also microadjustment and loading position.
10 cpi
A character spacing of 10 characters per inch. This is often the
standard or default pitch.
tractor
The part of the printer that moves continuous paper through the
printer by its sprockets gripping the holes in continuous paper.
12 cpi
A character spacing in which each character is slightly narrower
than normal, so that there are 12 characters per inch.
unidirectional printing
Printing in one direction only. Allows more precise vertical
alignment than bidirectional printing. Often used for printing
graphics.
user-defined characters
Characters that are defined and stored in the printer by the user.
Also known as downloaded characters.
