PC DRUM
8
The photoconductive drum used in this copier is the organic photoconductor (OPC) type.
The drum is made up of two distinct, semiconductive materials on an aluminum alloy
base. The outer of the two layers is called the Charge Transport Layer (CTL), while the
inner layer is called the Charge Generating Layer (CGL).
The PC Drum has its grounding point inside at the rear end. When the Imaging Unit is
installed in the copier, the shaft on which the PC Drum Drive Coupling Gear is mounted
contacts this grounding point.
Handling Precautions
This photoconductor exhibits greatest light fatigue after being exposed to light over an
extended period of time. It must therefore be protected from light by a clean, soft cloth
whenever the Imaging Unit has been removed from the copier. Further, use utmost care
when handling the PC Drum to prevent it from being contaminated.
