The charging system consists of a charging brush that is biased by power supply CHV and a discharge roller that is biased by power supply CBV. 2. 5021-0XX Basic structure of the print system The print system process consists of transfer drum is GND. General information 1-27 Frame potential of the following: 1. The OPC belt is biased to the -CBV(V) by power supply DCV. 3. The developer roller in the toner cartridge is then evenly charged to -DBV(V) by the OPC charging system. The OPC belt is biased to the negative high voltage by power supply DBV. 4.
