Product spec and feature

2.2.5 SMPS & HVPS

The SMPS and HVPS are on one integrated board.

The SMPS supplies the DC power to the system. It takes either 110V or 220V and outputs the +5V, -5V/0.5A, 12V and 24V supplies to the main and ADF PBAs.

The HVPS creates the high voltage of THV/MHV/Supply/Dev and supplies it to the toner cartridge. The CPU is used to modify some of these voltage settings to provide the ideal voltages to create the image.

The HVPS part uses the 24V and outputs the high voltage for THV/MHV/BIAS and the outputted high voltage is supplied to the toner, OPC cartridge and transfer roller.
