Introduction
Congratulations! You’ve purchased the Epson LQ-1500TM. This
advanced, state-of-the-art printer combines the quality of typewriter
print with the speed of a dot matrix printer. Of course, it has all the
capabilities of the other Epson printers-and more too.
LQ-1500 Features
The LQ-1500 is designed to be used day in and day out in an office
environment. Its size and rugged good looks proclaim this fact. Its
Epson engineering guarantees it.
The LQ-1500 has a long list of features. Just a few of the highlights
include:

Letter quality printing. The LQ-1500’s 24-pin print head can print
letter quality characters in four widths.
Proportional letter quality printing. The LQ-1500 can print in two
widths of proportional letter quality characters.
Draft speed. The LQ-1500 can print at 200 characters per second
using the draft character set.
Two hundred and twenty-four printing styles. The LQ-1500 can
print in 224 different printing styles, not counting superscripts and
subscripts.
Upward compatibility. The LQ-1500 includes all of the major features of the FX series of printers.
Userdefined characters. The LQ-1500 allows you to design your
own character sets, in either draft or letter quality mode.

High-resolution graphics. The LQ-1500 has all the graphics capabilities of the FX series of printers and more. The 24-pin print head
provides top-quality, high-resolution graphics.
Text buffer. The LQ-1500 has a 2048 character text buffer to increase
printing speed. The buffer takes information quickly from your
computer, leaving the computer free for other tasks while the
LQ-1500 finishes printing.
About This Manual
The LQ-1500 is a sophisticated machine. Although it is simple to
operate, writing programs for it can be complicated. In many cases,
the people who use the LQ-1500 are not the ones who do the programming. Therefore, Epson has provided two different manuals. This
LQ-1500 User’s Manual contains all the information required to set up
and operate, the LQ-1500. The LQ-1500 Programmer’s Manual contains the information required to write programs for the LQ-1500.
Epson also supplies Application Notes that tell you how to use the
LQ-1500 with specific software programs.
The first three chapters of this manual will help you set up, operate
and maintain your printer. Chapter 4 contains information on how to
use control codes with your printer.
The appendixes contain helpful information about selecting print
styles and character sets, and about using control codes to command
certain printer functions. Appendix A summarizes the control codes.
Appendix B explains how to change from one print style to another
and shows examples of different print styles. Appendix C shows the
character sets available on the LQ-1500, including the regular and
international sets. Appendix D gives the dot width of each of the
available proportional characters. Finally, Appendix E, a convenient
conversion chart, provides all the possible names for each ASCII
code.
This user’s manual is not long, but it contains a lot of important
information. In spite of its simple design, the LQ-1500 is a precision
printer, and you should know the right way to assemble and take care
of it. Reading this manual will help assure you of success when you
begin to use the LQ-1500.

Chapter 1
Setting Up Your LQ-1500
You’ve just purchased a terrific new printer, and dug far enough into
the box to find this manual. Now what? In this chapter we’ll show you
how to set up your LQ-1500 and connect it to your computer.
First, take inventory. Carefully unpack the carton and make sure
that you have all of the pieces shown in Figure 1-1:

This User’s Manual.
Note: It’s a good idea to save all of the packing materials in case you
want to move your LQ-1500 some day.
Finding a Suitable Location
Before you actually set up your printer, you should give some
thought to where you are going to put it. Of course, your printer must
sit somewhere near your computer (the length of the printer cable is
the limiting factor). However, you may not want to place your computer and printer side by side because the printer does make noise
3
Fig-we 1-1. Unpacking the LQ-1500
during operation. Here are some additional suggestions to follow:
1. Place the LQ-1500 on a flat, stable surface. The printer will make
more noise if you place it on a table that moves or vibrates.
2. Connect the printer to a grounded electrical outlet (do not use an
adapter plug). It’s a good idea to choose an outlet which is not
controlled by a wall switch that could be accidentally shut off during the printing process.
3. Choose a location which will allow enough space beneath or
behind the printer to load the paper. If you are using continuous (or
pin-feed) paper, the paper path should be free from obstruction
(see Figure 1-2).
4. Protect the printer from prolonged exposure to direct sunlight,
moisture, and dust. Make sure that it is not close to a heater or any
other heat source.
4
5. Use the LQ-1500 in areas that are comfortable for you. If you find
it too hot, too cold, or too humid, the environment is not right for
the LQ-1500; it may not operate properly.

Getting to Know Your Printer
Now you’ve got a small collection of odd-shaped pieces placed in a
suitable location. The next step is to put them all together to form a
functional printer. Figure 1-3 shows the assembled printer and identifies some of the main parts.
WARNING: To avoid shock hazard and prevent damage to the
LQ-1500, complete all of the installation procedures
described here with the power to the printer turned OFF.
Installing the paper feed knob
The first piece to install is the paper feed knob, which you use to
manually turn the platen and advance the paper-just as you do on a
typewriter. To install the paper feed knob, simply push it onto the
shaft on the right side of the printer. This is shown in Figure 1-4.

Figure 1-3. The LQ-1500 printer
6
Figure 1-4. Paper feed knob
Removing the dust cover
The dust cover is the brown plastic cover which keeps dust out of
the print mechanism and reduces the noise level when the printer is
on. If you are using the optional tractor unit, you will not use the dust
cover.
Lift off the dust cover. It just sits in a recess on the top of the printer
so removal is easy Set the dust cover aside if you will be needing it.
Put it away in the printer box if you plan to use the optional tractor
unit.
Removing the front cover
The next assembly step, installing the ribbon cartridge, first
requires a bit of disassembly. You should remove the front cover to
gain easier access to the print head when you install the ribbon.
Open the front cover by tilting the back edge up and toward you.
Push left and up. Gently lift off the cover and set it aside (see Figure
1-5). You’ll see it’s easier to do than it is to describe!
7
Figure 1-5. Removing the front cover
Discovering what’s inside
Now that you can see the insides of the printer, take a few moments
to find some of the parts that you need to know about. Study Figure
1-6 until you can identify these parts:
The print head is probably the easiest part to locate, so start with it.
The print head is the large, black, finned object that moves back and
forth on two silver rods across the printer.
The ribbon guide is the silver shield on the side of the print head
next to the paper. The ribbon guide guides the ribbon between the
print head and the paper.
The paper is guided through the printer by a large rubber roller
called the platen. It has the same function as the platen in a typewriter.
The paper bail is the numbered scale with three black rollers on it.
The paper bail rests against the platen and holds the paper in place as it
moves through the printer.
8
Figure 1-6. Printer parts
Once you identify these parts, you will know enough about the
printer to get started. This manual will help you identify other parts as
the need arises.
Installing the Ribbon Cartridge
The LQ-1500’s ribbon cartridge is easy to install, and it won’t get
your hands dirty. Follow these steps for a quick installation.
1. Close the paper bail so that it is against the platen.
2. Grasp the print head by the finned part and slide it along the silver
rods until it is positioned at 40 on the paper bail scale. You will need
space on either side of the print head when you insert the ribbon
cartridge.
3. Rotate the ribbon cartridge take-up knob in the direction indicated
by the arrow next to it so that the ribbon is tight (see Figure 1-7).
Don’t worry about wasting the ribbon by turning too much; the
ribbon is a continuous loop inside the ribbon cartridge.
9
Figure 1-7. Ribbon cartridge
4. Hold the ribbon cartridge in both hands to position it over the print
head (the hole in the ribbon cartridge fits over the finned part of the
print head). The short piece of exposed ribbon must go between
the print head and the ribbon guide so that the ribbon does not rest
directly against the platen (see Figure 1-8). Lower the ribbon cartridge and press the spot marked PUSH to seat the back of the
ribbon cartridge first.
5. Once you have positioned the exposed ribbon and secured the
back end of the ribbon cartridge, push down on the front of the
cartridge to snap it into place. The ribbon cartridge will sit level
when it is positioned correctly.
6. Now give the take-up knob several turns to straighten out the ribbon so that it is not wrinkled or twisted. The ribbon should move
freely between the print head and the ribbon guide (Figure 1-9).
10
Figure 1-8. Ribbon installation
Figure 1-9. Ribbon operation
To replace the front cover, simply reverse the steps you took to
remove it. Fit the right end into place first and then lower the left end
until it is securely in place. Tilt the cover back into the closed position.
It should fit snugly.
11
Installing the Sheet Guide
The sheet guide serves a dual purpose on the LQ-1500. If you are
using single sheets of paper, the guide ensures consistent margins and
straight lines of print. If you are using pin-feed paper, the sheet guide is
used as a paper separator to keep the incoming and outgoing paper
from interfering with each other.
Assembling the three pieces
First, you must assemble the three pieces of the sheet guide.
1. Orient the sheet guide so that the textured side is up and the metal
mounting pins are facing you. Lay one of the two sliding paper
guides on top of the sheet guide. The matching textured side should
be facing up and the lipped end should be facing toward you. Now
tilt the top of the sheet guide up so that you can hook the tabs at the
top of the sliding paper guide over the top edge of the sheet guide
(see Figure 1-10).
2.Next, turn the sheet guide over so the back side is facing you. Use
your thumbs to snap the the two plastic spring clips over the bottom edge of the sheet guide. One of the sliding paper guides should
now be securely in place.
3.Again, position the sheet guide so that the textured side is facing
you. Move the installed sliding guide to the proper end of the sheet
guide. The vertical standing edge of the sliding paper guide should
be flush against the outer edge of the sheet guide. The flattened side
of the sliding guide faces toward the center.
4. To install the other paper guide, just repeat the steps above. Be sure
to attach the second sliding guide with the vertical standing edge
facing out toward the end of the sheet guide and away from the
center (see Figure 1-11).
Attaching the sheet guide
To install the sheet guide, place the metal mounting pin on the right
side of the sheet guide into the corresponding hole in the metal frame.
Then lower the left side until the tab on the left side drops into the slot
in the metal frame. Figure 1-12 shows how to do this.
12

13
Figure 1-11. Paper guide position
Figure 1-12. Sheet guide installation
If you plan to use your LQ-1500 with single sheets of paper, lift up
the sheet guide at the back and fold down the metal legs on the bottom
of the sheet guide. As shown in Figure 1-13, the legs fit into slots in the
top case of the LQ-1500. (This step is not necessary if you will be using
the optional tractor unit.)
14
Figure 1-13. Printing single sheets
Once the sheet guide is installed you can replace the dust cover on
top, as shown in Figure 1-14. Also, you may want to remove the protective film that is on the switch panel at the right front of the
LQ-1500. This film protects the switch panel during manufacture and
shipment and can be easily peeled off.
Connecting the LQ-1500 to Your Computer
Your printer setup is now almost complete. The next step will be to
connect your printer to your computer. At the printer end of this connection, two additional pieces of equipment are required: an interface
card and a printer cable. The interface card consists of a circuit board
pre-mounted into a metal carrier (Figure 1-15).
Locating the interface card
Epson makes three types of interface cards for the LQ-1500: para1lel, serial, and IEEE 488. With the use of easily interchangeable interface cards, this powerful printer can be driven by nearly any
computer or word processor. Your Epson dealer can advise you about
which interface is best for your computer and application.

Installing the interface card
Your dealer may have already installed the interface card for you.
Turn your printer around and look at the back of the printer to tell if
the interface card has been installed (see Figure 1-16). If there is a large
cavity at the lower left, the interface card is missing and you must
install it before you can use your LQ-1500. If, on the other hand, there
is a plug connector at the lower left, the interface card has been
installed for you. (If your interface card has been installed, you can
skip to the next section.)
LQ-1500 with interface
card installed
Figure 1-16. Locating the interface card
17
The installation procedure is the same for all three of the available
interface cards. The card is easily mounted or removed. The only tool
you need is a Phillips screwdriver.
To install the interface card slide it into the cavity on the back of the
LQ-1500 as shown in Figure 1-17. It should slide between the upper
and lower plastic guide rails on either side of the opening.
When you feel resistance on the right side of the card, firmly push it
in with both hands. It may help to push against the card release levers
to snap the card into place. The interface card should be flush and
even with the back of the printer; it should not tilt or protrude.
Now, lift up slightly on the card and secure it in place with the
screws provided.
If you use your LQ-1500 with different computers, you may have to
remove and replace this card. Begin by removing the retaining screws.
Then pull the release levers on both sides of the interface card at the
same time. The card will slide out easily.
Attaching the cable to the printer
Note: Before you connect any cables, be sure that both the printer
and the computer are turned OFF.
One end of your printer cable should plug right into the connector
on the interface card (if it doesn’t, you have the wrong cable). To
secure the connection, attach the two clips on the interface card to the
cable (parallel interface only) or tighten the two screws on the cable
connecter (serial and IEEE 488 interfaces). If your cable has a ground
strap, connect it to the screw just above the interface connector. Figure
1-18 shows both types of connections.
Connecting the printer cable
For many computers, you merely plug the cable into the printer
port on your computer. Some computers require a printer interface
card, either mounted inside the computer or externally. Check your
computer installation and operations manual for details on how to
connect your computer to a printer.
18
Figure 1-17. Interface card installation
Setting the DIP Switches
This is the last step in installing your printer. Because each computer installation is slightly different, Epson has placed a series of DIP
switches on the back of theprinter interface, which you can change to
best suit your printing application. You can see them through a slot in
the back cover of the interface card.
19
Figure 1-18. Interface connection to computer
WARNING: The DIP switches we are discussing are in the interface
unit on the back of the printer. Do not change the settings of the DIP switches that are inside the printer.
These settings have been determined by the manufacturer to be correct for this LQ-1500 printer. Special
knowledge is required to set these switches.
You can use a ballpoint pen to reach into the interface slot and change
switch settings.
Note: Be sure that the printer is turned OFF before you make any changes
in the DIP switch settings. Your printer does not register changes in
switch settings made while the power is ON. You must reinitialize,
or restart, the printer to record the switch settings.
The switches are all numbered for identification. The number has
two parts. The first part refers to the switch group. Look at the back of
your printer; you will see one group of four and one group of eight
switches. You can identify the switch groups by looking at Figure 1-19.
As you can see, each switch group is actually a series of switches.
That’s the reason that each switch is referred to by two numbers. The
20
second digit refers to the individual switch number. It is printed right
on the switch itself.
You can also see that there is a small arrow on the left side of the
switch group which indicates the ON position for these switches.
However, it’s easier to remember switch settings according to whether
the switch is pointing up (toward the top of the printer) or down
(toward the bottom of the printer).

Switch 1-1--In the down position, this switch allows you to create a
buffer of 2048 bytes of memory. This buffer can be useful when you
want to print a document at the same time you continue to use your
computer for other tasks.
WARNING: If you turn OFF the LQ-1500, any information in the
buffer is lost.
Switch 1-2--Switch 1-2 enables a detector in the LQ-1500 that warns
you when the printer is out of paper. This is very important when you
are using continuous paper. The printer stops, issues an audible warning, and waits for you to load more paper before proceeding-and no
data is lost.
However, if you are using single sheets, the paper-out detector stops
the printer when it nears the bottom of the sheet (even if you want to
print all the way to the bottom or if you have another sheet ready to
feed). In this case, it is best to disable the paper-out detector by turning
switch 1-2 to the Up position. With the printer’s paper-out detector
disabled, the application software in your computer must determine
when it has come to the end of a page. Check with your software
dealer if you have difficulty.
Switch 1-3--Switch 1-3 controls whether or not the LQ-1500 does an
automatic line feed each time it receives a carriage return. Some computers do not send line feeds to the printer which means that this
switch must be up.
Switch 2
Switch 2 determines which print characteristics will be in use when
the LQ-1500 is turned on. Each of these functions can be changed at
22
any time by sending the appropriate command to the printer. The
functions of the individual switches are summarized in Table 1-2.

Switch 2-4.--Switch 2-4 is used to tell the LQ-1500 the size of paper
that you will be using. It uses this information to keep track of the
perforation and the top of the form.
Switch 2-5--The LQ-1500 automatically leaves a top and bottom
margin of 1/2 inch on each page if switch 2-5 is in the up position. The
switch tells the printer to skip over each perforation so that nothing is
printed on top of the perforation. This is especially useful for printing
long program listings. Many word processing programs, however,
23
have commands for setting top and bottom margins and they work
best if the skip-over-perforation feature is turned off.
Switch 2-6--There are occasions when the printer bell (which is actually a buzzer) can be used to signal the operator. For example, you
may want to switch paper in the middle of a long document. You can
use the bell to signal when it is time to make the change, To make use
of this feature, leave switch 2-6 down in the down position. For a
rough draft, it may not be necessary to switch paper, so by turning
switch 2-6 up, you won’t be bothered by unnecessary noise. Generally, switch 2-6 is left in the down position.
Switch 2-7--This switch also selects a feature that you may want to
use one way for rough drafts and another way for the final printout.
You can select either letter quality printing or draft printing. The
LQ-1500 prints much faster in draft mode, but the quality isn’t as
good. You can also change between draft and letter quality printing by
using commands sent from your computer.
Switch 2-8--This switch is used to control the select signal. Most computers require that the select signal be fixed (switch is in the up position). If your computer requires that the select signal not be fixed, then
set the switch in the down position.
If you have a parallel interface card, your installation is now complete! Go on to Chapter 2, where you’ll learn how to operate the
LQ-1500.
If, on the other hand, you have a serial or IEEE 488 interface card,
you have a few more switches to set in order to ensure that your computer and LQ-1500 are communicating properly. Consult your interface user manual for instructions on the proper setting of these
switches.
Installing the Power Cord
If you have been following along so far you should have one piece
left: the power cord. Plug one end into the LQ-1500--the connection
is on the rear of the printer near the right side (as you face the rear).
Plug the other end into a standard (120 VAC, 60 Hz) grounded electrical outlet (do not use an adapter plug).
24
Chapter 2
Operation and Maintenance
Your LQ-1500 is now set up. You’ve connected it to your computer
and set the switches. Now you’re ready to learn how to use the controls and indicators on the printer to operate it correctly. We’ll also
give you some advice on how to maintain your LQ-1500 and keep it
printing smoothly for a long time.
Then, in Chapter 3, you’ll learn how to install and load the paper
feeders which will give you an opportunity to use the controls discussed here.
Controls and Indicators
There are several controls and indicators on the LQ-1500 (see Figure
2-1). You use them to operate the printer and make your day-to-day
printing easier for you. Here’s what these controls do:
The power switch
The power switch is located on the left side (toward the rear) of the
printer. Press the front side of the switch to turn the printer ON; press
the back side to turn it OFF.
The control panel
The control panel, located on top of the computer, has indicator
lights and buttons which monitor the printing process. They are:
l
POWER light -- glows green when the power is ON.
• READY light -- glows green when the printer is ready to accept
data. The light flickers somewhat during transmission. This flickering is normal.
25
Power switch
Figure 2-1. Controls and indicators
l
l
l
PAPER OUT light -- glows red when the printer is out of paper;
printer will stop printing (if Switch 1-2 is in the up position).
ON LINE light -- glows green when data reception is possible.
ON LINE button -- allows you to switch from on-line to off-line
status (this is a toggle). When the printer is on line, it is ready to
accept data from the computer and the ON LINE light glows green.
When the printer is off line, it is not ready to print.
When the printer is off line, you can use the form feed (FF) and line
feed (LF) buttons on the control panel to move the paper. The ON
LINE and READY lights will be off. You can return the printer to
on-line operation at any time, just by pressing the ON LINE button.
l
26
FF button -- stands for form feed. When you’re off line, pressing
this button will advance the paper to the top of a new page.
l
l
LF button -- stands for line feed. When you’re off line, tapping this
button advances the paper one line at a time. To advance multiple
lines, hold down the LF button. Do not perform continuous line
feeds for more than two minutes.
SHEET LOAD button -- opens the paper bail and loads singlesheet paper into the printer.
The paper-out detector
The printer is equipped with a device which warns you that the
printer is out of paper. When your paper runs out, printing stops, the
PAPER OUT light goes on, and the printer buzzer sounds five times.
When you have loaded more paper, the PAPER OUT light goes off.
Printing can be resumed in one of two ways. If you are in the middle
of printing, press the ON LINE button. If you want to reinitialize the
printer, turn the power switch OFF and then back ON.
You can turn off the paper-out detector in two ways: by DIP switch
1-2 on the interface card, or by a control code sent from the computer.
Turning off the paper-out detector tells the printer to ignore the paperout sensor and allows you to print to the bottom of the page. Some
computers will stop the printer before the end of the page, even
though DIP switch 1-2 is down (off). If this happens, you may need to
consult your dealer about the interface between your computer and
printer. You may also consult your software dealer for further information.
Maintenance
As with any mechanical device, the best maintenance of your
LQ-1500 is preventive maintenance. You’ve already started by choosing a clean, dust-free location with a comfortable temperature range.
Of course, you will change your ribbon cartridge whenever it loses
quality through use.
In addition, your printer requires periodic cleaning. Here are a few
tips on how to perform this maintenance properly.
Cleaning the LQ-1500
You should clean the outside of the printer case whenever it appears
to be dirty. Use a clean damp rag and alcohol. Be careful not to drip
alcohol on the printer mechanism.
27
You should also clean the inside front portion of the printer (Figure
2-2) to get rid of dust and paper lint. To do this, turn the power switch
off and disconnect the power cord. Remove the dust cover, the front
cover, and the ribbon cartridge. Use a small vaccum cleaner and a soft
brush to clean inside the printer. Be careful not to bend or damage any
of the parts inside the printer. With the power off, you can easily move
the print head back and forth to clean under it. Use as light a touch as
possible to get the job done.
Figure 2-2. Maintenance
Other maintenance
Changing the ribbon cartridge and cleaning the printer are the only
maintenance tasks that you should do. There are no user-serviceable
parts inside the LQ-1500. Leave any other types of maintenance
(fuses, print heads, etc.) for your Epson dealer or authorized service
center. The LQ-1500’s print head is not user-replaceable because it
must be carefully aligned with special tools to achieve the best printing
quality
28
Chapter 3
Installing Paper and Paper Feeders
Now that you are more familiar with your LQ-1500, you’re ready
to install and load the paper feeders. Since you’re into the third chapter, you’re probably getting anxious to print something by now. First,
you need some facts on the different types of paper and paper feeders
the LQ-1500 uses.
Types of Paper and Paper Feeders
You can use a great variety of paper types with the LQ-1500 which
makes your printing both flexible and convenient. Paper thickness can
range from 0.07 mm to 0.20 mm for both types of paper feeders.
Single-sheet paper and sheet guide
First, you can use single-sheet paper including all the standard sizes
of stationery and preprinted business forms. Single-sheet paper may
vary in width from 7.2 to 14.3 inches. The sheet guide unit is used to
feed single-sheet paper into the LQ-1500. As you may recall, Chapter
1 gave you the details for installing the sheet guide unit.
Pin-feed paper and tractor unit
Second, you can use pin-feed paper (also called continuous-feed
paper). This includes the familiar fan-fold paper with pin-holes on
either side, pin-feed labels, and other types of continuous forms. The
LQ-1500 will handle pin-feed paper from 4 to 16 inches wide. Pin-feed
paper is used with an optional tractor unit which pulls the paper
through the printer by the pin holes.
29
More Printer Parts
You also need to become familiar with two other important printer
parts before you attempt to load any type of paper. Remove the dust
cover and open the front cover to find and identify these parts: the
platen release lever and the print head adjustment lever.
Platen release lever
The platen release lever controls the pressure of the friction rollers
against the platen. It is the black lever located on the left side of the
printer at the end of the platen (as shown in Figure 3-1). This lever has
two settings: engaged (back) and released (forward).
Figure 3-1. Adjustment levers
The first setting, engaged, is used with the single-sheet feed operation which is also called friction feed. In this position the pressure of
the friction rollers against the paper causes it to feed through the
printer.
30
The second setting, released, is used when the tractor unit is in
place. The platen release lever is pulled forward toward the front of
the printer. In this position, the friction rollers do not catch the paper
but allow it to move freely through the paper path. The tractor unit is
installed above the platen and draws the paper through by its pin
holes.
Print head adjustment lever
The space between the print head and the platen should be adjusted
to accommodate the thickness of the paper you’re using. Thicker
paper needs a wider space to allow for clean printing and smooth
paper movement. Open the front cover of your printer. You’ll find
that the print head adjustment lever is a small black-tipped lever
located on the left side of the printer in front of the platen release lever
(as shown in Figure 3-1).
The print head adjustment lever has five positions to widen or narrow the space between the print head and the platen. Move the lever
back (toward the rear of the printer) to decrease the space and forward
(toward the front of the printer) to increase the space. Most paper of
standard thickness should be accommodated with the lever in the
straight-up position.
Loading Single-Sheet Paper
Printing on single-sheet paper is fast and easy with the LQ-1500.
The printer does most of the work and does it the same way every
time. Your main responsibility is to set each sheet of paper in the sheet
guide unit evenly and press the correct button. We’re sure you’ll agree
this method is much easier than setting up your paper manually each
time you insert a new sheet.
Preparing the printer for single-sheet feed
The following steps tell you how to prepare the printer for singlesheet feed.
1. Remove the dust cover and front cover. Remove the tractor unit if
it is installed.
31
2. Install the sheet guide unit and place it in the upright position (see
Chapter 1 for details). Line up the left edge of the left sliding guide
with the 1 on the paper bail. This is very important because paper
near the center or the right side of the platen will not be detected by
the printer.
3. Be sure that switch 1-2 is in the up position to disable the paper-out
detector. This allows the printer to print to the end of the page.
Remember that your computer is now responsible for stopping the
printer when it reaches the end of the paper.
4. Close the paper bail so that it rests against the platen.
5. Engage the platen release lever by pushing it toward the rear of the
printer.
6. Set the print head adjustment lever for the paper you are using.
Remember that upright is the right adjustment for most paper.
7. Replace the front cover and dust cover.
Loading single-sheet paper
Now that you have prepared the printer, you can load the paper
into the sheet guide unit. Remember to load one sheet at a time.
Follow the steps outlined below and refer to Figure 3-2 to load
single-sheet paper into the printer.
1.Place a single sheet of paper in the sheet guide unit and adjust the
paper guide on the right to the width of the paper. The paper
should be square in the guide. Tap the top of the paper gently to
work it down into the printer.
2.
If the printer is OFF, turn it ON. The PAPER OUT light should be
off. If it is on, then the paper is not down in the printer far enough
or it is not far enough to the left side of the platen.
3.Press the ON LINE button to put the printer into off-line mode.
Both the READY and ON LINE lights are off.
4. Press the SHEET LOAD button. The paper will begin to automatically feed into the printer and the paper bail will open. After the
paper has been loaded, the paper bail will automatically close.
32
Paper
Figure 3-2. Sheet load
Note: If the paper does not advance far enough to be held by the paper
bail, turn OFF the power, remove the dust cover, open the paper
bail, and use the paper feed knob to advance the paper to the
proper position. This problem is caused by not having the paper
far enough down in the printer when you press the SHEET
LOAD button. You may damage your printer parts if you do
this repeatedly with the power ON.
If the paper is not straight in the printer, press the FF (FORM FEED)
button; the paper feeds the rest of the way through the printer.
Remove the paper and place it back in the sheet guide unit. Repeat
step 4 to reload the paper.
WARNING: Do not move the paper backward through the printer
because it may damage the paper-out detector.
5.
Return the printer to the on-line mode by pressing the ON LINE
button. The ON LINE and READY lights should now be on.
You are now ready to print! Repeat the steps above to print more
single pages.
33
Removing single-sheet paper
To remove single-sheet paper from the printer, set the printer in the
off-line mode by pressing the ON LINE button (remember its’s a toggle). The ON LINE and READY lights should now be off. Press the FF
(FORM FEED) button and the paper will be ejected from the printer.
Loading Pin-feed Paper
Pin-feed paper is used quite frequently. It is convenient if you do
lots of printing or want to use special pin-feed forms such as labels. It
is also very convenient for printing rough drafts of documents where
you can use less expensive paper.
Loading the LQ-1500 with pin-feed paper is not difficult, but it does
require that you have the optional tractor unit purchased separately
from your dealer. As with single-sheet feed, the printer does most of
the work and virtually takes care of itself until the paper runs out. All
you have to do is load the paper correctly.
Installing the tractor unit
The following steps show you how to prepare the printer for pinfeed paper (see Figures 3-3 and 3-4).
1. Turn OFF the printer. Remove the dust cover and the front cover.
2. If the sheet guide unit is installed, lay it back flat against the top of
the printer. It should not remain in the upright position when you
install the tractor unit.
3. Remove the small protective cover on the right side of the printer
to make room for the tractor unit. It is retained by a single Phillips
screw as shown in Figure 3-3. Put the piece away in a safe place.
4. Locate the metal brackets on either side of the printer. These brackets have two functions: they hold the sheet guide unit and the tractor unit. Notice that there are two unused wedge-shaped slots
which will hold the tractor unit. Pick up the tractor unit by each
end and slip the tiny silver pegs into the open slots (see Figure 3-4).
34
Figure 3-3. Protective cover removed
5. Gently tilt the tractor unit toward you and push the tractor unit
down until you feel it lock into place.
Preparing the printer for pin-feed paper
With the tractor unit now installed, you can prepare the printer to
load the pin-feed paper. Follow the steps outlined below and refer to
Figure 3-5.
1.
Set DIP switch 1-2 in the down position to enable the paper-out
detector. This allows the printer to stop printing and signal when
you are out of pin-feed paper.
2.Open the paper bail by pulling it forward (toward the front of the
printer).
3.
Unlock the gray pin-feeder lock levers on the tractor unit by pulling them toward the front of the printer and slide both pin-feeders
outward to the sides. Open the black covers on the pin-feeders.
35
Figure 3-4. Tractor unit installation
36
Figure 3-5. Printer parts used with pin-feed paper
4. Set the paper support skids evenly from the approximate center of
the paper width (as shown in Figure 3-6). This helps the paper feed
smoothly.
Note: If you are using narrow or standard width paper, you must
insert it at the far left of the platen (just as you did with singlesheet paper).
5. Make sure the platen release lever is closed (back).
Inserting pin-feed paper
Now that you have prepared the printer, you can load the pin-feed
paper by following these steps:
1. Make sure you have a clean top edge. Insert the pin-feed paper into
the paper guide slit at the rear of the platen as shown in Figure 3-6.
(If the sheet guide unit is installed, slide the paper underneath it.)
37
Advance the paper by turning the paper feed knob clockwise.
With the platen release lever closed, the paper should easily catch
on the platen and be fed through.
Figure 3-6. Paper inserted
Note: If the paper is not feeding correctly (or easily), stop, turn the
paper feed knob counterclockwise, and at the same time gently
pull the paper back out. Check the paper to be sure it is not
wrinkled or torn and try again.
2. Stop turning and release the platen release lever (pull it forward)
when the top of the paper reaches the two pin-feeders. The paper
should now be free to move without using the paper feed knob (see
Figure 3-7).
3. Adjust the pin-feeders to the paper width by sliding them inward to
line up with the paper pin-holes. Place the paper pin-holes onto the
tractor pins, close the pin-feeder covers, and adjust the paper tension by pulling the pin-feeders gently apart (see Figure 3-8).
38
Figure 3-7. Aligning pin frames
Note: Position wide paper so that the printable surface is between 1
and 136 on your paper bail (the holes will be outside of these
margins on the left and right).
5. Lock the pin-feeders in place by pushing the gray pin-feeder lock
levers back.
6. Confirm that the tractor pins are centered in the paper pin-holes
and that the paper tension is correct. If they are not, open the pinfeeder covers, readjust the paper, and close them again.
7. Close the paper bail.
8. Set the print head adjustment lever according to the thickness of
your paper.
9. Turn the paper feed knob clockwise to advance the paper until the
print head is positioned just under the first perforation which separates one page from another.
10. Install the tractor unit dust cover.
11. Turn the printer on. The ON LINE and READY lights should now
be on.
39
Figure 3-8. Pin-feeder covers
Proper placement of pin-feed paper
When using the LQ-1500 with pin-feed paper, we recommend that
you arrange your stack of paper in one of two ways.
First, if you use a stack of paper and have to place it behind the
printer, make sure that it is not higher than the surface of the sheet
guide unit. Placing the paper behind the printer makes it difficult for
the printed paper to be collected without interfering with the printer
operation. You have to watch the paper more closely.
Second, if you have room to place the paper on the floor, you
should arrange it as shown in Figure 3-9. It’s best to leave the paper
right in the box. We recommend this type of paper placement if at all
possible.
Be sure that the paper is free to unfold in an accordian fashion with
no obstructions that would hinder the movement of paper through the
printer. You’re now ready to print with continuous-feed paper!
40
Figure 3-9. Paper path
Removing pin-feed paper
If you want to remove the pin-feed paper from the printer, follow
the steps outlined below:
1.Remove the (tractor) dust cover.
2. Tear the paper at the perforation nearest the rear of the printer.
3. Set the printer in the off-line mode by pressing the ON LINE button. The ON LINE and READY lights should now be off.
4. Open the pin-feeder covers (on the tractor unit) and remove the
paper from the pins. Make sure the platen release lever is in the
forward (released position).
5. Gently pull the paper up through the paper path until it is free from
the printer.
Removing the tractor unit
If the tractor unit is installed on the printer, you will have to remove
it to use the single and automatic sheet feed options.
Follow the steps outlined below to remove the tractor unit from the
printer and refer to Figure 3-10.
41
Figure 3-10. Removing the tractor unit
1. Turn OFF the printer. Remove the (tractor) dust cover.
2. Release the metal lock levers on each end of the tractor unit by
pulling them forward (toward the front of the printer).
3. Keeping the lock levers pulled forward, move the entire tractor
unit toward the front of the printer and up. The pegs at each end of
the unit will slide out from the slots on the printer.
The LQ-1500 Self-Test
Now that you are an expert on loading your LQ-1500, you’re ready
to print. The LQ-1500 self-test is a built-in program which generates a
complete printing of all standard characters. The self-test also provides an opportunity to test the ribbon and paper installation without
having to request a printout from your computer. In fact, you can
perform the self-test without a computer at all! Try it yourself and see
by completing the following steps.
1. Install 14-inch wide paper.
42
2.
With the power OFF hold down the LF (LINE FEED) button and
turn the printer ON. Watch as all the characters are printed as
shown in Figure 3-11. You can release the LF button once printing
begins.

3. Turn the printer OFF to end the test. Otherwise, it will continue to
print indefinitely.
Now, it’s time to start learning to communicate with your LQ-1500.
Chapter 4 shows you how to do this efficiently and effectively.
43
Chapter 4
Control Codes
This chapter introduces you to the control codes you can use to
send instructions from your computer to your printer. If you already
know how to program your printer, you’ll want to know how control
codes work with the LQ-1500. You’ll also be interested in Appendixes
A and E which provide the control codes.
Please note that this chapter contains technical information and
you don’t have to read it in order to operate your printer or to perform
ordinary word processing operations. If you don’t know how to program a printer, you can use your applications software to find out
how to control the LQ-1500.
Computer-to-Printer-Communications
Alphabetical characters (letters) are foreign to computers; computers only know numbers. However, computers still manage to do a
good job of manipulating the letters that we use for word processing.
The secret lies in the fact that a computer doesn’t manipulate letters at
all-it just manipulates numbers that represent letters and turns these
numbers into the letters that we see on the screen and the printout.
The computer communicates with the printer by means of numerical codes. There are 256 different codes that the computer can send to
the printer, represented by the numbers from 0 to 255. Since there are
many different kinds of computers and many different kinds of printers, a standard set of codes was developed that almost all computers
use to comunicate with printers. This set of codes is called the American Standard Code For Information Interchange, or ASCII for short.
There are ASCII codes for all the letters in the alphabet (both upperand lowercase), the numbers from 0 to 9, most punctuation marks,
45
and some of the LQ-1500’s functions. Because of these standard codes,
you can use your LQ-1500 printer with virtually any kind of computer without having to worry about their ability to talk to each other.
Your LQ-1500 printer can communicate with any computer that uses
ASCII.
How Many Names Can One Code Have?
Although these codes are standard from computer to computer, the
way they are referred to is not standard. The same ASCII code can be
called by many different names. For example, the letter A is represented by the decimal number 65 in ASCII. This code may either be
called A or 65. In the BASIC programming language, this code may
be referred to as CHR$(65).
At other times, ASCII codes are referred to by their hex value. Hex
is short for hexadecimal, which is a base-16 numbering system (our
usual numbering system is a base-10 system). Since 16 digits are
required for a base-16 number system, hex uses the digits 0 through 9
and the letters A through F. In hex, A is 41H, where the H stands for
hex.
Most of the time we don’t have to give this code system a thought. If
you press A on the keyboard, the computer sends the code to print an
A to the printer.
Some ASCII codes don’t have keys on the keyboard. The most
important of these are the codes that have values of less than 32. These
codes are used to control many of the LQ-1500’s functions. Most keyboards can produce these codes, by holding down the control key
(often marked CTRL) while pressing a letter key. The combination of
CRTL/A produces ASCII 1, CTRL/B produces ASCII 2, and so on.
Because of the way these codes are created, they are often referred to
as control A, control B, etc.
Most of these control codes also have names that describe their
functions. For example ASCII 13, which is the code to start a new line,
is called carriage return. The following chart shows many different
ways of referring to the code for the carriage return function.
46
Carriage return
CR
13
0DH
CTRL/M
CHR$(13)
Its common name
The abbreviation of its name
Its decimal ASCII code
Its hexadecimal ASCII code
Its control-code name
Its usage in BASIC
So your problem is to figure out what code you want to use, no
matter what it is called. You may find that this can be quite a problem.
Your computer’s manual may say to use ASCII 10 while your spreadsheet program recommends a CTRL/J. You need to know that they
are both talking about the same code.
This manual tells you the different names for the same code.
Appendix A gives a complete summary of all the control codes (also
called commands). Appendix E contains a conversion chart for all the
common names for the ASCII codes.
Some of the LQ-1500’s functions are controlled by codes consisting
of one character. These are the ASCII codes with decimal values
between 1 and 31, and are the codes that you can type by holding the
control key while you press a letter key. For example, the code ASCII
12 is the same as CTRL/L and advances the paper to the top of a new
page.
Of course the LQ-1500 has many more than 31 functions. To use the
many additional functions, you use one special code to enable all the
control codes that consist of more than one character. This code is
called Escape, and in this manual it is abbreviated as <ESC> . You will
use this code often with the LQ-1500 because it allows you to use the
many features of the printer.
Here is an example of how the escape code is used. It may seem
tricky at first, but follow along and you’ll soon understand. The code
to turn on the italic print function is <ESC> “4”. The 4 in this code is
the numeral 4, not ASCII 4; the numeral 4 is ASCII 52.
Remember that the ASCII codes 0 through 32 have commonly used
abbreviations for their names. In these cases we use the abbreviations.
<ESC>q is the abbreviation for escape, which is also ASCII 27.
Therefore, the <ESC> “4” that turns on italic print actually is ASCII
27 followed by ASCII 52. But <ESC> “4” is easier to understand and
remember.
47
Here are some other common abbreviations:

Line Feed
Form Feed
Carriage Return

<LF>

You now have the basics about codes. This knowledge should help
you understand and use the information contained in your software
documentation to take advantage of the LQ-1500's many features.

Appendix A
LQ-1500 Command Summary
This appendix gives a brief summary of the LQ-1500 commands
(control codes). While this is a complete list of the commands, the
descriptions are not complete in all cases. The complete descriptions
of all the commands, including examples of their use, can be found in
the LQ-1500 Programmer’s Manual.
In some cases the explanations given here describe the apparent
function of the commands, rather than the actual mechanical movements of the printer. For example, since the printer prints in both
directions, the line feed command may not actually return the print
head to the left margin if the next line prints from right to left, but the
final effect on the printed page is the same as if it had.
The commands are organized into five logical groups: Vertical
Spacing Commands, Horizontal Spacing Commands, Character Set
Commands, Graphics Set Commands, and Miscellaneous Commands. The function is what the printer will do when given the proper
command. The format is the correct syntax for the ASCII code that
the printer undertands. This code may expressed as a symbol, a decimal value, or a hexadecimal value depending on the program you are
using. Where n (or another italic letter) is used as a variable, it stands
for a numerical value.

Appendix B
Changing Printing Style
The LQ-1500 can produce 224 different styles of printing. Although
there are many commands to select these different styles of printing,
there is one command that lets you choose at will between any of
them. This command is called Master Select. The Master Select command consists of <ESC> “!” followed by a single ASCII code. The
value of the ASCII code determines the printing style that is selected.
A typical Master Select command might look like this:
(ESC) "!" 66
This command would select italic proportional print. In BASIC the
same command would look like this:
LPRINT CHR$(27) "!" CHR$( 66);
On the following four pages are charts showing each of the printing
styles that the LQ-1500 can produce. Following each example is the
ASCII code (decimal) that will select a particular print style.
The first of the four charts shows the proportional print styles.
These styles are available in both the Letter Quality and Draft sets.
The second chart shows the printing styles that are available in the
Letter Quality set. The third and fourth charts show the printing styles
that are available in the Draft set.
The letters, MISwiy were chosen to represent typical wide,
medium, narrow, and descending characters. The letters are represented in these print styles: regular, emphasized, double-strike, and
emphasized and double-strike.
69
The Select Print Quality command will select either the Letter Quality or the Draft set. The Select Print Quality command looks like this:
<ESC> “x” 0 To select the Draft set
<ESC> "x" 1 To select the Letter Quality set
In BASIC this command would look like this:
LPRINT CHR$(27) "x" CHR$(0);
or
LPRINT CHR$(27) "x" CHR$(l);

Widths of the
Proportional Characters
This table lists the widths of the LQ-1500’s proportional characters.
The values given are in 360ths of an inch (for example: a value of 36 is
36/360 inch). You may need to enter these widths into a special table
for your word processing program so that it can calculate the number
of proportional characters that will fit on each line. The table shows:
the character, its ASCII code (decimal) and lists four widths. Figure
D-1 shows what each of the four width values are for. The total width
value is the only width that you will probably need to know. The leftspace, body and right-space widths are all values that are internal to
the LQ-1500.

Using the LQ-1500 Commands with BASIC
Most versions of BASIC use the LPRINT command and the CHR$(n) function to send codes to the printer. In the CHR!$(n) function the value n is the
number of the code that you want to send to the printer. For example, to set a
right margin at column 60, the LQ-1500 command is:
<ESC> “Q” 60
In BASIC it looks like this:
LPRINT CHR$(27) “Q” CHR$(60);

Master Select Codes
Each print style is assigned a value to be used with the Master Select command. The Master Select command consists of <ESC> "!" followed by a single ASCII code. To create a master select code, add the values of the print
styles that you want to combine.
The values of the print styles are as follows:
1
2
4
8
Elite
Proportional
Condensed
Emphasized
Double-strike
Enlarged
Italic
Underlined
16
32

For example, if you want to find the code for elite emphasized italic print
you would add these values:
Elite
Emphasized
Italic
Master Select code
1

The Master Select command would look like this:
(I is ASCII 73)
(ESC) "!" “I”
Note: Proportional overrides pica/elite.
