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-color image on the ITB.
The four colors are transferred to the paper at the same time by the
ITB drive roller. The paper transfer roller does not have a charge.
