The durable layer of organic photoconductor (OPC) is coated over the aluminum cylinder base. The OPC tend to reduce
its own electrical conductance when exposed to light. After a cyclic process of charging, exposure, and development, the
electrostatic image is constituted over the OPC layer.
Since the OPC is materialized by resin, it is susceptible to damage caused by sharp edges such as a screwdriver, etc.,
resulting in a print quality problem. Also, finger prints can cause deterioration of the OPC layer, therefore, the drum (in the
drum unit) must be handled with care. Substances like water, alcohol, organic solvent, etc., should be strictly avoided.
As with all other OPC drums, the exposure to a strong light source for a prolonged period can cause a print quality prob-
lem. The limit is approximately 500 lux for less than five minutes. If the drum (drum unit) remains removed form the printer,
it should be stored in a cool, dark place.
