3 Main charger grid bias (C)
4 Main charger grid bias (K)
Out3 1 Developer bias (Y)
2 Developer bias (M)
3 Developer bias (C)
4 Developer bias (K)
Out4 1 1st transfer roller bias (Y)
2 1st transfer roller bias (M)
3 1st transfer roller bias (C)
4 1st transfer roller bias (K)
Out5 - 2nd transfer roller bias
Notes:
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.
