1. Cleaning brush roller

3. OPC drum
This machine has four independent PCUs, one for each color. Each PCU consists
of an OPC drum, non-contact charge roller, cleaning brush, and cleaning blade.
The diameter of the drum is 30 mm (circumference: about 94.25 mm).
The photoconductor gap between a PCU and the corresponding development roller
is determined by the drum positioning plate and the rear shaft, and is not
adjustable in the field.
The push switches in the drum positioning plate detect when a new PCU has been
installed.
