• The drum consists of two distinct, light-sensitive, organic semiconductor 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).

• It is a type that is sensitive to the near infrared wavelength.

• Size = φ100 × 350mm

Handling Precaution

The PC Drum exhibits light fatigue after being exposed to light for a long time, which results

in its sensitivity being changed. Therefore, always wrap the drum in the PC Drum Cloth or

a soft cloth immediately after it has been removed from the copier.
