1.3 Product-Inherent Cautions
Laser Light

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
