PC DRUM

• The PC Drum used in this copier is the organic photoconductor (OPC) type.
The drum consists of an aluminum base coated with a charge generation layer and a
charge transport layer.
Handling Precautions
Prolonged exposure to light can cause the photoconductor surface of the drum to suffer
light fatigue, resulting in a loss of photosensitivity. If the I/C is removed from the copier, it
should be wrapped in a soft, clean, opaque cloth or other protective covering to prevent
exposure to light.

Gear
• Grounding of the PC Drum
The PC Drum ground point is located inside and at the front end of the I/C as viewed
from the front of the copier and in constant contact with the Drum Holding Shaft. When
the I/C is installed in the copier, the Drum Holding Shaft contacts the ground point. This
provides for assured grounding of the PC Drum through the ground plate in the rear to
the frame of the copier.
