This machine has four tandem PCUs. Therefore, four color developments are possible

during one paper path. This improves the productivity of outputs in color printing mode.

Each PCU contains identical components (drum unit, development unit and so on), but the

PCUs are not interchangeable.

The diameter of the drum is 40 mm (circumference: about 125.7 mm).

The photoconductor gap between a drum and the corresponding development roller is not

possible to adjust because these are assembled as a PCU at the factory.

The ID chip is part of the TD sensor assembly. The ID chip contains counters and other

data about the PCU, drum unit, and development unit. If you replace the development unit

with a new one, the counter information for the drum unit is not kept on the new ID chip.
