1. Unpacking and Installation
1-1. Unpacking
After unpacking the unit, check that all the necessary accessories are included in the package.
Note:The ferrite core and fastener provided with your
printer depend on your printer conguration.
Fig. 1-1 Unpacking
If anything is missing, contact the dealer where you bought the printer and ask them to supply
the missing part. Note that it is a good idea to keep the original box and all the packing materials
just in case you need to pack the printer up again and send it somewhere at a later date.

1-2. Choosing a place for the printer
Before actually unpacking the printer, you should take a few minutes to think about where
you plan to use it. Remember the following points when doing this.
P Choose a rm, level surface where the printer will not be exposed to vibration.
PThe power outlet you plan to connect to for power should be nearby and unobstructed.
PMake sure that the printer is close enough to your host computer for you to connect
the two.
PMake sure that the printer is not exposed to direct sunlight.
PMake sure that the printer is well away from heaters and other sources of extreme heat.
PMake sure that the surrounding area is clean, dry, and free of dust.
PMake sure that the printer is connected to a reliable power outlet. It should not be on
the same electric circuit as copiers, refrigerators, or other appliances that cause power
spikes.
PMake sure that the room where you are using the printer is not too humid.
WARNING
PShut down your equipment immediately if it produces smoke, a strange odor, or unu-
sual noise. Immediately unplug the equipment and contact your dealer for advice.
PNever attempt to repair this product yourself. Improper repair work can be dangerous.
PNever disassemble or modify this product. Tampering with this product may result in
