Opc Charge And Cleaning - Ricoh G165 Service Manual

AIO (All In One) Cartridge

6.4.3 OPC CHARGE AND CLEANING

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.
