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

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.
