2.2.4.2 HVPS and SMPS Board
The HVPS Board and SMPS Board housed in one board.
The HVPS board creates the high voltage of THV/MHV/Supply/Dev and supplies it to the developer portion,
so as to develop the optimum image quality. The HVPS portion takes the 24V and outputs the high voltage
for THV/MHV/BIAS, and supplied to the high voltage, OPC cartridge, and transfer roller for optimum latent
image and toner transfer quality.
It is the power source of entire system. It is assembled by an independent module, so it is possible to use for
common use. It is mounted on the side of the machine.
It is consisted of the SMPS portion, which supplies the DC power for driving the system, and AC to power the
Fuser Unit. SMPS has two output channels, which are +3.3V and +24V.
