Application of grease
Grease must not be applied to any parts that are not so designated. Also, never use any other
than the specified type of grease. Otherwise, plastic parts and rubber parts may melt or be
otherwise deformed.
Attaching and removing cables
Attaching and removing cables with the power still on may cause breakdowns and should
be avoided. In particular, flat cables are likely to cause short circuit.
When attaching or removing cables, always be sure to turn the power off.
1.3 Product-Inherent Cautions
Laser Light
Do not perform any tasks outside the scope of work indicated in the manual. (If exposed to
laser light, the retina of the eye can permanently be damaged.)
Further, the laser scanner unit must not be disassembled or modified under any
circumstances.
Handling of the Transfer Charging Roller
The presence of oils or the like on the sponge portion of the transfer charging roller leads to
faults in the printer. Do not hold the transfer charging roller by its sponge portion during
service work.
Handling the Fixing Unit
The presence of oils or the like on the surface of the pressure roller or the fixing film found
inside the fixing unit can cause fixing faults or jams. Do not hold the pressure roller during
service work.
