Low-voltage power supply circuit
The low-voltage power supply circuit converts AC voltage from a power supply receptacle to DC
power and supplies the fuser with the power to drive its heater.
The low-voltage power supply circuit has two components:
● Fuser control circuit: controls the temperature of the fuser.
● Low-voltage power supply circuit: generates the DC power required inside the printer and
supplies the AC power to the fuser control circuit.

in this document. Also, ITB unit and transfer unit refer to the same assembly and are used
