Low-voltage Power Supply Control
Overview
This circuit converts the AC voltage to DC power supply and provides it to each load.
Description
The following shows a block diagram of the low voltage power supply and fixing power supply .
• Low voltage power supply: Generates the DC power supply needed inside the printer.
• Fixing power supply: Provides AC power supply to the low voltage power supply and controls the fixing heater temperature
of the Fixing Assembly.
The low voltage power supply starts to operate when the AC power supply is connected to the inlet. The AC power supply is
converted to +24 V, which is the DC power supply required by the printer, and +3.3 V.
