4.1.3 TRANSFER BELT UNIT
1. Never touch the transfer belt surface with bare hands.
2. Take care not to scratch the transfer belt, as the surface is easily damaged.
3. Before installing the new transfer belt, clean all the rollers and the inner part of
the transfer belt with a dry cloth to prevent the belt from slipping.
4.1.4 SCANNER UNIT
1. When installing the exposure glass, make sure that the white paint is at the rear
left corner.
2. Clean the exposure glass with alcohol or glass cleaner to reduce the amount of
static electricity on the glass surface.
3. Use a cotton pad with water or a blower brush to clean the mirrors and lens.
4. Do not bend or crease the exposure lamp flat cable.
5. Do not disassemble the lens unit. Doing so will throw the lens and the copy
image out of focus.
6. Do not turn any of the CCD positioning screws. Doing so will throw the CCD out
of position.
4.1.5 LASER UNIT
1. Do not loosen the screws that secure the LD drive board to the laser diode
casing. Doing so would throw the LD unit out of adjustment.
2. Do not adjust the variable resistors on the LD unit, as they are adjusted in the
factory.
3. The polygon mirror and F-theta lenses are very sensitive to dust. Do not open
the optical housing unit.
4. Do not touch the glass surface of the polygon mirror motor unit with bare
hands.
