Transfer Roller; Scanner Unit; Laser Unit; Fusing Unit - Gestetner B130 Service Manual

PRECAUTIONS
2. Never use alcohol to clean the drum. Alcohol will dissolve the drum surface.
3. Store the PCU in a cool dry place.
4. Do not expose the drum to corrosive gases (ammonia, etc.).
5. Do not shake a used PCU, as this may cause toner and developer to spill out.
6. Dispose of used PCU components in accordance with local regulations.

3.1.5 TRANSFER ROLLER

1. Never touch the surface of the transfer roller with bare hands.
2. Be careful not to scratch the transfer roller, as the surface is easily damaged.

3.1.6 SCANNER UNIT

1. Use alcohol or glass cleaner to clean the exposure and scanning glass. This
will reduce the static charge on the glass.
2. Use a blower brush or a water-moistened cotton pad to clean the mirrors and
lenses.
3. Take care not to bend or crease the exposure lamp's ribbon cable.
4. Do not disassemble the lens unit. Doing so will throw the lens and copy image
out of focus.
5. Do not turn any of the CCD positioning screws. Doing so will cause the CCD to
be misaligned.

3.1.7 LASER UNIT

1. Do not loosen or adjust the screws securing the LD drive board on the LD unit.
Doing so will cause the LD unit to be out of adjustment.
2. Do not adjust the variable resistors on the LD unit, as these are permanently
adjusted at the factory. If replacement of the LD drive board is necessary,
replace the entire LD unit.
3. Keep the polygon mirror and toroidal lens free of dust. Laser performance is
very sensitive to dust on these components.
4. Do not touch the shield glass, the lenses, or the surface of the polygon mirror
with bare hands.

3.1.8 FUSING UNIT

1. After installing the fusing thermistor, make sure that it is in contact with the hot
roller and that the roller can rotate freely.
2. Be careful to avoid damage to the hot roller stripper pawls and their tension
springs.
3. Do not touch the fusing lamp and rollers with bare hands.
4. Make sure that the fusing lamp is positioned correctly and that it does not touch
the inner surface of the hot roller.
