Introduction
The Epson LQ-800 and LQ-1000 are state-of-the-art, X-pin dot-
matrix printers that deliver exceptional speed and sharpness in either
Letter Quality or draft style.
The LQ-800 and LQ-1000 are also capable of a wide variety of print
enhancements, including:
LETTER QUALITY
DRAFT
Bold

Underlining

The LQ-800 and LQ-1000 combine the versatility and reliability of
Epson products, with a wide range of exciting new features.
l
You can select either the Letter Quality or draft typestyle with a
touch of a front panel button-there are no codes to learn.
l
The 24-pin print head produces sharp, crisp draft characters, and
Letter Quality characters that look like they came from a type-
writer.
l
The LQ has built-in connectors for both parallel and serial interface
cables, so there’s no need for extra options or modifications.
l
Option cartridges are available to further extend the capabilities of
the LQ-800 and LQ-1000. These cartridges provide additional type
fonts, and will also allow you to use programs designed for other
popular printers.
Intro-1
l
The compact design and light weight of the LQ make it ideal for
home and business applications.
l
A 7K buffer frees your computer so you can work on one document
while printing another.
Using this manual
To make it easier to set up your new LQ-800 or
LQ-1000,
this man-
ual includes a 10-step guide to setting up your printer. These steps take
you from unpacking, through ribbon and paper loading, to printing
your first document.
Easy-to-read tabs make it simple for beginners or experienced users
to find information. Additional sections describe how to use your new
printer with word processors, create graphics, define your own char-
acters, and more.
If you are familiar with earlier Epson manuals, you’ll find two terms
changed to make them more descriptive. In this manual, double-
width
is used instead of expanded, and condensed is used in place of
compressed.
Intro-2
Chapter 1
Setting Up Your LQ Printer
Setting up your new LQ is easy. Simply follow the steps in this
chapter.
Note
The LQ-800 and LQ-1000 are essentially the same printer
except that the LQ-1000 can accept wider paper. Therefore,
most of the illustrations in this manual show only the LQ-800.
If there is a difference that you need to know about, a separate
illustration shows the LQ-1000.
1
Unpacking Your Printer
First, remove the printer from the box and take off all outside
plastic covering and foam supports. See that you have received all the
parts shown in the illustrations on the next page. (You’ll find the paper
feed knob inserted in the foam packing material.)
1-1
Figure 1-1. The LQ-800
Figure 1-2. The LQ-1000

Remove the tape that holds the dust cover in place during shipping
and take the cover off the printer. Simply tilt the dust cover up and lift
it off the printer.
WARNING
The print head is protected by two plastic bumpers during shipping.
Both of these bumpers
must
be removed before turning on the printer.
Remove the long bumper to the right of the print head first, then move
the print head to the center of the LQ and remove the small bumper
on the left side of the print head.
There is a clear plastic overlay on the control panel to protect it
from scratching and discoloration. It’s up to you whether you remove
the overlay or leave it on.
Installing the paper feed knob
Next install the paper feed knob. To install the knob, simply push it
onto the shaft on the right side of the printer, as shown in Figure 1-3.
The shaft has one flat side that must be matched with the flat side of
the hole in the knob.
Figure 1-3. Installing the paper feed knob
1-3
Now that you’ve installed the paper feed knob, use it to remove the
sheet of paper wrapped around the printer’s platen (the black roller).
2
Selecting the Right Location
The most important consideration in choosing a location for
your printer is that it be close enough to connect a cable to your com-
puter. But also keep the following tips in mind:
l
Place the printer or printer stand on a solid and level foundation.
Avoid setting it on carpet, chairs, or unstable surfaces.
l
Use a grounded outlet-one that has three holes to match the power
plug on the printer. Don’t use an adapter plug.
l
Avoid using electrical outlets that are controlled by wall switches-
if you accidentally turn off a switch, you could wipe out valuable
information and stop your printing.
l
Keep your printer and computer away from base units for cordless
telephones.
l
Avoid using an outlet on the same circuit breaker with large electri-
cal machines or appliances that might disrupt the flow of power to
your printer.
l
Protect your printer from direct sunlight, and keep it away from
excessive heat, moisture, and dust. Make sure it’s not too close to a
heater or any other heat source.

3
Installing the Ribbon
With the dust cover removed, you have easy access to the
printer for ribbon installation and paper loading. The next time you
install a ribbon or load paper, you can leave the cover on.
Now you’re ready to install the ribbon.
1. Manually move the print head to the middle of the platen.
WARNING
The power must be OFF when moving the print head. Moving
the print head when the power is ON may damage your
printer. If you’ve been using your printer just before changing
the ribbon cartridge, be careful not to touch the print head
because it becomes hot during use.
2.
Before loading the cartridge into the printer, turn the small knob on
top in the direction of the arrow to tighten the ribbon as shown in
Figure
1-4.
Figure 1-4. Tightening the ribbon
1-5
3. For the LQ-800, hold the ribbon cartridge by the raised plastic fin
on top of the cartridge; for the LQ-1000 hold the cartridge by the
two plastic tabs. Lower the cartridge into the printer, guiding the
two square pins on each. end of the cartridge into the slots in
the printer frame, as shown in Figures 1-5 and 1-6. Press firmly on
each end of the cartridge to make sure the pins are firmly seated in
the slots.
Figure 1-5. Loading the LQ-800 ribbon cartridge
Figure 1-6. Loading the LQ-1000 ribbon cartridge
1-6
4. Now use the point of a pencil to guide the ribbon into place
between the ribbon guide and the print head as shown in Figure
1-7. (There is also a diagram on the top of the ribbon cartridge
itself.)
Figure 1-7. Positioning the ribbon
5. With the cartridge in place, again turn the ribbon knob in the direc-
tion of the arrow to tighten the ribbon.
And that’s it-the ribbon is now installed.
1-7
Replacing the ribbon. . .
When buying new ribbon cartridges for the LQ-800 or 1000, be sure
you get a ribbon specifically for the LQ-800 or 1000. Ribbon cartridges
for other Epson printers, such as the FX series, may closely resemble
an LQ ribbon, but their use can damage the LQ print head. Also,
ribbon cartridges for the LQ-1500 will not fit the LQ-800 or 1000, and
the Epson ribbon replacement pack #8758 should not be used as a
replacement ribbon.
The LQ uses a continuous-loop, inked fabric ribbon. When your
printing becomes too light, replace the ribbon with a fresh cartridge.
To replace the ribbon, just pull up on the raised fin on top of the
LQ-800 cartridge, or the two plastic tabs on the LQ-1000 and lift the
cartridge out of the printer. To install a new ribbon, follow the preced-
ing steps.
4
Loading Single-Sheet Paper
When you receive your LQ, it is set up to print on single sheets
of paper.
Even if you have purchased one of the optional paper feed-
ing systems (the cut sheet feeder or the tractor unit), you should
first
complete the remaining setup steps before installing either of the
optional systems.
It is much easier to run the self test (Step 8) and to connect the LQ to
your computer (Step 9) before you install an optional system. After
completing the setup steps, see Chapter 2 for installing the cut sheet
feeder, or Chapter 3 for installing the tractor unit.
Installing the single-sheet guide
Now install the single-sheet guide. It helps you feed individual
sheets of paper into the LQ.
First, put the edge tab into the guide frame. Holding the plastic
spring, insert it into
the groove as shown below.
