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.
