2.2.1.8 SMPS & HVPS Section
The SMPS supplies DC Power to the System.
It takes 110V/220V and outputs the +5V, +24V to supply the power to the main board and DADF board.
The HVPS board creates the high voltage of THV/MHV/Supply/Dev and supplies it to the developer part for
making best condition to display the image. The HVPS part takes 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.
