Power Supply
The HVPS section generates and supplies the following voltages:
■ Transfer Voltage
■ Charge Voltage
■ Bias Voltage
■ Supply Voltage
The Bias, Supply, and Charge voltages are used by the Print Cartridge.
The power distribution section receives AC voltage and creates the required DC outputs (3.3
VDC, 5 VDC, and 24 VDC) to power the printer components. It also supplies AC voltage to
the Fuser Assembly.
