Applies voltage in sequential correspondence with primary charging, developing, transfer, discharging, attraction, and separation. Supplies separation output to the fuser unit and the separation charging unit / corona. Controls the various loads and various detection functions (motors. developing unit, fuser unit, transfer drum peripherals, pick-up/high voltage/paper feeder, etc.). Controls the pick-up system loads. Relays signals between the DC controller and the video controller. Detects the cassette size. Detects the toner amount (Emitting unit). Detects the toner amount (Receiving unit). Detects the waste toner bottle is full. Detects the oil amount. 5-12
