Important Safety Instructions
Read all of these safety instructions before using the printer. In
addition, follow all warnings and instructions marked on the
printer itself.
❏
Do not place the printer on an unstable surface or near a
radiator or heat source.
❏
Place the printer on a flat surface. The printer will not operate
properly if it is tilted or placed at an angle.
❏
Do not block or cover the slots and openings in the printer’s
cabinet, and do not insert objects through the slots.
❏
Use only the type of power source indicated on the printer’s
label.
❏
Connect all equipment to properly grounded power outlets.
Avoid using outlets on the same circuit as photocopiers or air
control systems that regularly switch on and off.
❏
Do not use a damaged or frayed power cord.
❏
If you use an extension cord with the printer, make sure the
total ampere rating of all devices plugged into the extension
cord does not exceed the cord’s ampere rating. Also, make
sure that the total ampere of all devices plugged into the wall
outlet does not exceed the wall outlet’s ampere rating.
❏
Unplug the printer before cleaning it, and always clean it with
a piece of damp cloth only.
❏
Do not spill liquid onto the printer.
❏
Except as specifically explained in this guide, do not attempt
to service the printer yourself.

You must remove all protective materials packed around and
inside your printer before you set it up and turn on the power.
Follow the directions on the Notice Sheet (packed with the
printer) to remove these materials.
Save all packing and protective materials in case you need to ship
the printer in the future. It should always be transported in its
original packing materials.
Choosing a place for the printer
Follow the guidelines below when selecting a location for your
printer.
❏
Place the printer on a flat, stable surface. The printer will not
operate properly if it is tilted or placed at an angle.
❏
Place the printer where you can easily connect it to a network
interface cable, if necessary.
❏
Leave adequate room around the printer for easy operation
and maintenance.

❏
Avoid using or storing the printer in places subject to rapid
changes in temperature and humidity. Keep it away from
direct sunlight, strong light, heat sources, or excessive
moisture or dust.
❏
Avoid places subject to shocks and vibrations.
❏
Place the printer near a wall outlet where you can easily
unplug the power cord.
❏
Avoid electrical outlets controlled by wall switches or
automatic timers. An interruption in power can erase
information in the memory of your printer or computer. Also
avoid outlets on the same circuit as large motors or other
appliances that can cause voltage fluctuations.

❏
Keep the entire computer system away from potential sources
of electromagnetic interference, such as loudspeakers or the
base units of cordless telephones.

paper-release lever is pushed back to the single-sheet position
and the paper guide is in the upright position, as shown
below.

Connecting the Printer to Your Computer
Your printer includes both an IEEE-1284-compatible parallel
interface and an EIA-232D serial interface. Before you begin, place
the printer upright, as shown below. (This makes it easier to
connect the cable.)
Connect your computer to the desired interface as described
below.
Note:
You can connect a cable to both interfaces; the printer switches
automatically to the appropriate interface when it receives data.
Using the parallel interface
You need a shielded, twisted-pair cable no longer than 2 meters
(6 feet) to use the parallel interface.
Follow these steps to connect the printer to the computer using
the parallel interface:
1.Turn off both the computer and the printer.
1-16
Setting Up the Printer
2.Plug the parallel cable connector securely into the printer’s
parallel interface port. Squeeze the wire clips together until
they lock in place on both sides of the connector.
Note:
If there is a ground wire at the end of the cable, attach it to the ground
connector located to the right of the parallel interface port.

3.Plug the other end of the cable into the computer’s parallel
interface port. (If there is a ground wire at the end of the cable,
attach it to the ground connector at the back of the computer.)

Using the serial interface
You need a serial cable that has a DB-25 male connector on the
printer side to use the serial interface.
Follow these steps to connect the printer to the computer using
the serial interface:
1.Turn off both the computer and the printer.
2.Plug the serial cable connector securely into the printer’s
serial interface port. Tighten the screws on both sides of the
connector.
