2.4.5 PC Drum
The PC Drum used in this machine 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 machine, it should be wrapped in a
soft, clean, opaque cloth or other protective covering to prevent exposure to light.

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
machine and in constant contact with the Drum Holding Shaft. When the I/C is installed in the machine,
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 machine.
