2.4 Power Supply Unit (PSU)
The power supply unit receives the input line voltage and currents it to output voltages of +5 VDC, +24
VDC, +12 VDC, and -12 VDC.
The heater circuit controls output voltage to the fuser heater according to instructions received from the
heater control circuit.
If an over-current is sensed in the secondary circuit, power is interrupted.
Power supply unit block diagram
The power supply unit has two output connectors.
The following table shows the connector outputs:
CN101 -- to the Fuser Heater
Pin No. 1 2
Output L N
CN2 -- to the Main Control PCB.
