High-Voltage Transformer Setting
The high-voltage transformers (PS-HVT-450) supply high-voltage to the parts related to charging,
development, transfer and Discharging blade.
The high-voltage transformer has the following high-voltage outputs.
CH1
1
Main charger needle (Y)
2
Main charger needle (M)
3
Main charger needle (C)
4
Main charger needle (K)
CH2
1
Main charger grid bias (Y)
2
Main charger grid bias (M)
3
Main charger grid bias (C)
4
Main charger grid bias (K)
CH3
1
Developer bias (Y)
2
Developer bias (M)
3
Developer bias (C)
4
Developer bias (K)
CH4
1
1st transfer roller bias (Y)
2
1st transfer roller bias (M)
3
1st transfer roller bias (C)
4
1st transfer roller bias (K)
CH5
-
2nd transfer roller bias
CH6
1
Recovery blade bias (Y)
2
Recovery blade bias (M)
3
Recovery blade bias (C)
4
Recovery blade bias (K)
Note:
Never move the variable resistance on the board since the output adjustment has been
performed 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.
