Checking the Parts
When you unpack the printer, make sure that you have all the parts
shown below and that none have been damaged.

Setting Up the Printer
After removing the parts, save the packing materials in case you
ever need to transport your printer.
The ribbon cartridge that comes with the LQ-850 is #7753; #7754
comes with the LQ-1050.
Removing the Protective Materials
The printer is protected during shipping by two locking brackets,
two locking tabs, and a print head protector. These protective items
must be removed before you turn on the printer. After removing
these items, store them with the other packing material in case you
ever need to transport your printer.
1.
Remove the printer cover unit, which includes the printer cover
and the paper guide cover.

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 memory and in your
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.
1-8
Setting Up the Printer
The illustration below shows a good printer arrangement.
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.
Setting Up the Printer
1-9
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
You use the platen knob 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 platen knob into the hole on the printer’s side and
rotate it slowly until it slips onto the shaft.
1-10
Setting Up the Printer
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 cartridges are designed for easy installation
and removal. You install. the standard ribbon cartridge and the
optional film ribbon cartridge in the same way. A standard ribbon
cartridge comes with your printer.
Install the ribbon cartridge as follows:
1.
Make sure the printer is turned off.
2.
Remove the printer cover unit.
Setting Up the Printer
1-11
3.
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.
4.
Turn the ribbon-tightening knob in the direction of the arrow.
This removes slack in the ribbon and makes it easier to install.
1-12
Setting Up the Printer
5.
Hold the ribbon cartridge by its black, fin-like handles with the
exposed ribbon away from you. (The LQ-850 ribbon cartridge
has only one handle.) Push the cartridge firmly into position,
making sure the plastic hooks fit into the slots inside the printer.
Note: Press lightly on both ends of the cartridge to make sure
the plastic hooks are properly seated.
Setting Up the Printer
1-13
6.
Use a pointed object, such as a ballpoint 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.
7.
Slide the print head from side to side to make sure it moves
smoothly. Also check that the ribbon is not twisted or creased.
Make sure the paper thickness lever on the left is set to
position 2. See The Paper Thickness Lever in Chapter 2 if you
are printing on special paper.
1-14
Setting Up the Printer
CAUTION: Film ribbon cartridges must be used and
stored within the following temperature ranges:
Operation: 41°F to 95°F (5°C to 35°C)
Storage: -22°F to 104°F (-30°C to 40°C)
Storing and using a film ribbon at high temperatures
shortens the ribbon’s life expectancy, which is normally
200,000 characters (#7768) or 300,000 characters (#7770). If
you continue to use the ribbon beyond its life expectancy,
printing suddenly becomes faint and the ribbon may snap.
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 as shown below. Make sure
the back edge of the guide is even with the back of the printer.
Setting Up the Printer
1-15
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.
