Four PCDUs, one laser unit (four laser beams).
Each PCDU contains an OPC drum and a development unit.
Bias rollers above each OPC drum pull the four developed toner
images to the ITB, to deposit a four-colour image on the ITB.
The four colours are transferred to the paper at the same time by the
ITB drive roller. The paper transfer roller does not have a charge.

Here is a close-up of the main print engine.
The ITB drive roller pushes the toner from the ITB onto the paper. The paper
transfer roller does not pull the toner.
