1. Note for servicing
Pictogram
This Service Manual uses some pictographs to assure safe operation.
Please understand the meanings of pictographs before servicing.
CAUTION: If this CAUTION is ignored, an injury or damage to property
could occur.
A.Cautions for servicing
1) Do not touch the photoconductive drum. Scratches or smudges on
the drum will cause dirty printouts.
2) The fusing unit is extremely hot. Exercise care in this area.
3) Do not look directly at the light source of the scanner module. Doing
so may damage your eyes.
4) Five adjusters are provided on all optional stand/paper drawer units.
These adjusters should be lowered until they contact the floor.
5) Do not make any modifications to this machine. Doing so may result
in personal injury or damage to the machine.
6) Since this machine is heavy, it is recommended that it be moved by
more than one person to prevent injury.
7) When connecting this machine to a computer, be sure to first turn
both the computer and the machine off.
8) Do not print anything which is prohibited from printing by law. The
following items are normally prohibited from printing by national law.
Other items may be prohibited by local law.
•Money
•Stamps
•Bonds
•Stocks
•Bank drafts
•Checks
•Passports
•Driver's licenses
9) Do not throw toner or a toner cartridge into fire. Toner may be
spattered, causing a burn.
10) Store toner or toner cartridges in a hard-to-reach place for children.
