Opc Charge And Cleaning - Ricoh PE-P1 Service Manual

AIO (All In One) Cartridge

OPC Charge and Cleaning

6
This machine uses a charge roller [A]. The charge roller gives the drum surface a negative charge. The
high voltage supply board, which is at the left side of the machine, applies a dc and ac voltage (at a
constant current) to the roller. The ac voltage helps to make sure that the charge given to the drum is as
constant as possible.
The machine automatically controls the charge roller voltage when process control is done.
The charge roller cleaner 1 [B] and charge roller cleaner 2 [C], which always touch the charge roller,
clean the charge roller. The OPC cleaning blade [D] removes the waste toner on the OPC. The toner
collection coil [E] moves the toner to the waste toner transport belt.
