TIPS FOR PRINTING ON SINGLE SHEETS
There are a few things you should know about printing on single
sheets as opposed to continuous paper. When you print on single
sheets, you may notice that your printer prints the first page of
your file correctly but then prints too low on the next page, or that
it prints the last few lines from one page onto the next.
These differences in print position are easy to adjust; you can
simply change some of the settings in your application program as
described below to get the right results.
1. When you install an application program, it normally asks you
what printer you are using. Make sure you choose the correct
printer. See Chapter 1 for the right printer to choose.
2. Many programs include an option to set the maximum lines per
page. If your program has a lines-per-page setting and you are
using standard 8½ x 11-inch paper, set the lines per page to 61.
Note: To find the right lines-per-page setting for paper that is not
8½ x 11, create a test document using your application program.
Set your top and bottom margins to 0 and then create a file of
numbered lines from 1 to 66. When you print your file, notice
the last number printed on the first page. This is your maximum
lines-per-page setting.
3. If your program doesn’t have a lines-per-page setting, try
decreasing the top margin or increasing the bottom margin, or
both, until you get the results you want.
4. You can also try adjusting the form length setting. For a
standard 8½ x 11-inch page, try setting the form length at
10 inches.
5. Some programs also let you indicate whether you are using
single sheets or continuous paper. Make sure you choose single
sheets.

printer. For more information on these options, see Chapter 4.
Single-Bin Cut-Sheet Feeder
(C80637* for LQ-570, C80639* for LQ-1070)
This economical cut-sheet feeder automatically feeds up to 50
sheets of paper into your printer without reloading. You can
load continuous paper and manually load single sheets without
removing the cut-sheet feeder.
High-Capacity Cut-Sheet Feeder
(C80638* for LQ-570, C80640* for LQ-1070)

feeder to the single-bin model.
Pull-Tractor Unit
(C80019* for LQ-570, C80022* for LQ-1070)
Although you can use the standard tractor as a pull tractor,
using the optional pull tractor improves printing accuracy,
which is especially useful for printing on continuous multi-part
forms.
Film Ribbon Cartridge
(#7768 for LQ-570, #7770 for LQ-1070)
An optional film ribbon cartridge provides even higher quality
printing than the standard fabric ribbon.
Interface Cards
Optional interface cards are available to supplement the printer’s
built-in parallel interface. Guidlines for choosing the right
interface and instructions on installing the cards are given in
Chapter 4.
The last figure in option part numbers, represented by an asterisk

Unpacking the Printer
Checking the parts
When you unpack the printer, make sure you have all the parts
shown below and that none is damaged.
Printer
Power cord Ribbon cartridge
Note: In some locations the power cord may be attached to the
printer.
Store the packing materials in case you ever need to transport your
printer.
CAUTION: There are several versions of the printer
designed for different voltages, and it is not possible to
adjust the printer for use at another voltage. If the label
on the back of the printer does not show the correct
voltage for your country, contact your dealer.
1-2 Setting Up the Printer

Choosing a Place for the Printer
When selecting a place to set up your printer, be sure to follow the
guidelines below.
l Place the printer on a flat, stable surface.
l Place the printer close enough to the computer for the printer’s
interface cable to reach it.
lLeave adequate room around the printer to allow for easy
operation and maintenance.
CAUTION: Avoid locations that are subject to direct
sunlight, excessive heat, moisture, or dust.
lUse a grounded outlet; do not use an adapter plug.
l Place the printer where you can easily unplug the power cord.
l Avoid electrical outlets controlled by wall switches or automatic
timers. Accidental disruption of power can wipe out information
in the memory of your printer or computer.
lAvoid outlets on the same circuit as large motors or other
appliances that can cause fluctuations in line voltage.
l 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 1-3

Choosing a Place for the Printer
If you plan to use a printer stand, follow these guidelines:
Use a stand that supports at least 16.0 kg (35.3 lbs) for the
LQ-570 or 22.0 kg (48.5 lbs) for the LQ-1070.
Never use a stand that tilts the printer at an angle of more than
15 degrees from horizontal. If you install a cut-sheet feeder, the
stand must keep your printer level.
If you plan to load continuous paper through the bottom of the
printer, choose a stand that provides an unobstructed paper
path.
Position your printer’s power cord and interface cable so they
do not interfere with paper feeding. If possible, secure the cables
to a leg of the printer stand.
Align the paper stack so that the paper feeds straight into the
tractor’s sprocket units.
1-4 Setting Up the Printer

Assembling the Printer
Removing the protective materials
During shipping, packing materials protect the printer and a locking
clip protects the paper-tension unit. Before you turn on the printer,
you must remove the locking clip as described here:
1. Remove the paper guide. Lift the printer cover up and off.
Grasp both ends of the clear plastic paper-tension unit; lift up
the front of the unit and then lift it off.
2. Remove the locking clip from the paper-tension unit.
Note: Store the clip with the other packing materials in case you
ever need to transport your printer.
Setting Up the Printer 1-5

Assembling the Printer
Installing the ribbon cartridge
Before installing the ribbon cartridge, make sure that the power
cord is not plugged into an electrical outlet.
1. If necessary, lift the printer cover up and off. Grasp both ends
of the clear plastic paper-tension unit and lift it up and off also.
WARNING: Never move the print head while the printer is
turned on; this can damage the printer. Also, if you just
used the printer, the print head may be hot. Let it cool
for a few minutes before touching it.
2. Slide the print head to the middle of the printer.
1-6 Setting Up the Printer

Assembling the Printer
3. Turn the ribbon-tightening knob in the direction of the arrow.
This removes any slack in the ribbon and makes it easier to
install. Next, hold the ribbon cartridge by its handle and push it
firmly down into position; then press on both ends of the
cartridge to make sure the plastic hooks fit into the slots.
4.Use a pointed object, such as a ball point pen, to guide the
ribbon between the print head and ribbon guide. Turn the
ribbon-tightening knob to help feed the ribbon into place.
5.Slide the print head from side to side to make sure it moves
smoothly. Also check that the ribbon is not twisted or creased.
