Before You Start
M095/M096/M099/M100 4-2 SM
Laser Unit
1. Do not loosen or adjust the screws securing the LD drive board on the LD unit. Doing so will
throw the LD unit 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 or the surface of the polygon mirror with bare hands.
5. Do not adjust the Laser Synchronization detector on the LD unit, as these are permanently
adjusted at the factory.
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.
Fusing
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.
Paper Feed
1. Do not touch the surface of paper feed rollers.
2. To avoid misfeeds, the side and end fences in each paper tray must be positioned correctly
so as to align with loaded paper size.
Scanner Unit (for M099/M100)
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. Make sure to not bend or crease the exposure lamp’s ribbon cable.
4. Do not disassemble the lens unit. This will cause the lens and copy image to get out of
focus.
5. Do not turn any of the LED positioning screws. This will put the LED out of position.
