2.2.3.2 OPC Drum
An OPC (Organic Photo Conductor) is used.
This photoconductor is of a laminate type consisting of a carrier generation layer and
an electric charge retaining layer applied onto an aluminum base (cylinder).
(See “Figure 2-14”)
Grounding of OPC drum:
The grounding contact of the photoconductor is located in its front inside and
always in contact with the shaft of the front plate of the print unit. When the print
unit is installed in the printer body, the setting pin of the print unit front plate
comes in contact with the front plate of the printer body to achieve grounding.
Thus, the electric charge on the photoconductor in the area exposed to light is
grounded through the grounding plate, the shaft and the setting pin to the frame.
(See
“Figure 2-15”)

Precautions in Handling:
The organic photoconductor can deteriorate by sensitivity change
due to light fatigue if it is exposed to light for an extended period of
time. To prevent such deterioration, when the OPC Drum has been
taken out of the printer body, cover it with a clean soft cloth to
protect it from exposure to light. In handling the Photoconductor
Unit, take great care that no dirt adheres to the surface of the
photoconductor.
