Service Remarks; Handling The Drum - Ricoh FT5535 Service Manual

1. SERVICE REMARKS

1.1 HANDLING THE DRUM

The organic photoconductor (OPC) 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 fingers 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.
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 photoconductive 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 its protective sheet when it is 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. Apply setting powder to the entire surface of the drum before installing a
new drum.
9. Process control data initial setting (see section 3.1, "Practical SP Mode
Use Tables - Replacement and Cleaning") must be performed when a
new drum is installed.
