1.3 HANDLING THE DRUM
The organic photoconductor drum is comparatively more sensitive to light
and ammonia gas than a selenium 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 with a dry cloth or clean 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 inserting or pulling the
drum unit out of the copier to avoid exposing it to bright light or direct
sunlight. This will protect the drum from light fatigue.
9. Before inserting or pulling out the drum unit, the following should be
performed to avoid damaging the drum:
a) Remove the cleaning unit.
b) Remove the development unit.
c) Remove the charge corona unit.
d) Release the transport unit.
10. Before pulling out the drum unit, place a sheet of paper under the drum to
catch any dropped toner.
11. Drum initial setting (SP #66) must be performed when a new drum is
installed.
NOTE: This is not necessary at installation of a new machine as the drum
initial setting is performed at the factory.
12. Dispose of the used drum according to local regulations.
