1. SERVICE REMARKS
1.1 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 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.
3. Never use alcohol to clean the drum; alcohol dissolves the drum
surface.
4. Store the drum in a cool, dry place away from heat.
5. Take care not to scratch the drum as the drum layer is thin and is
easily damaged.
6. Never expose the drum to corrosive gases such as ammonia gas.
7. Always keep the drum in the protective sheet when keeping the
drum unit, or the drum itself, out of the copier. Doing so avoids
exposing the drum to bright light or direct sunlight. This will
protect the drum from light fatigue.
8. Before inserting or pulling out the drum unit, the following should
be performed to avoid damaging the drum:
a) Remove the black and color development units
b) Remove the cleaning unit
c) Remove the charge corona unit
d) Lower the T&S corona unit
9. Drum initial setting (SP66) must be performed when a new drum
is installed.
