4. REPLACEMENT AND ADJUSTMENT
4.1 GENERAL CAUTIONS
Never turn off the power switch while the machine is operating.
If the machine is switched off during operation, the transfer belt, drum, or
development unit could be damaged when it is removed or reinstalled in the
machine.
4.1.1 DRUM
An organic photoconductor (OPC) drum is more sensitive to light and ammonia gas than a
selenium drum. Follow the cautions below when handling an OPC drum.
1. Never expose the drum to direct sunlight.
2. Never expose the drum to direct light of more than 1,000 Lux for more than a minute.
3. Never touch the drum surface with bare hands. When the drum surface is touched with
a finger or becomes dirty, wipe it with a dry cloth or clean it with wet cotton. Wipe with a
dry cloth after cleaning with wet cotton.
4. Never use alcohol to clean the drum; alcohol dissolves the drum surface.
5. Store the drum in a cool, dry place away from heat.
6. Take care not to scratch the drum as the drum layer is thin and is easily damaged.
7. Never expose the drum to corrosive gases such as ammonia gas.
8. Always keep the drum in the protective sheet when keeping the drum unit, or the drum
itself, out of the machine. Doing so avoids exposing it to bright light or direct sunlight,
and will protect it from light fatigue.
9. Dispose of used drums in accordance with local regulations.
10. When installing a new drum, execute SP2962 (Adjustment of Drum Conditions).
4.1.2 DRUM UNIT
1. Before pulling out the drum unit, place a sheet of paper under the drum unit to catch
any spilt toner.
2. Make sure that the drum unit is set in position and the drum stay is secured with a
screw before the main switch is turned on. If the drum unit is loose, poor contact of the
drum connectors may cause electrical noise, resulting in unexpected malfunctions
(RAM data change is the worst case).
