3.8 High-Voltage Transformer Setting
3.8.1 General description
The high-voltage transformers (PS-HVT-350) supply high-voltage to the parts related to charging,
development, transfer and drum cleaning.
The high-voltage transformer has the following high-voltage outputs.
CH1: Main charger wire
CH2: Main charger grid bias
CH3: Color developer bias
CH4: Black developer bias
CH5: 1st transfer roller bias
CH6: 2nd transfer roller bias
CH7: Cleaning blade bias
Note: Note:
Never move the variable resistance on the board since the output adjustment has been per-
formed at the shipment for the high-voltage transformer supplied as a service part. Also do not
perform the setting change when the high-voltage power supply is replaced.
