GENERAL CAUTIONS August, 2006
3-2
3.1.3 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 a 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.
3.1.4 SCANNER UNIT
1. When installing a new exposure glass, make sure that the white paint mark 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 lenses.
4. Never bend or crease the exposure lamp cables.
5. Never disassemble the lens unit. Doing so will throw the lens and the copy
image out of focus.
6. Never adjust any CCD positioning screw. Doing so will throw the CCD out of
position.
3.1.5 LASER UNIT
1. Never 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. Never adjust the variable resistors on the LD unit, as they are adjusted in the
factory.
3. Never open the optical housing unit. The polygon mirror and lenses are
sensitive to dust.
4. Never touch the glass surface of the polygon motor unit with bare hands.
