Smps And Hvps - Ricoh AC205 Service Manual

6.4 SMPS AND HVPS

The SMPS (Switching Mode Power Supply) and HVPS (High Voltage Power
Supply) are located on the same board. The SMPS supplies either 110V or 220V
DC power to the system, and outputs +5V, +12V and +24V supplies to the Main
and other PBAs.
The HVPS creates the high voltage of THV/MHV/Supply/Dev, and supplies it to the
toner cartridge. The CPU modifies some of these voltage settings to provide the
ideal voltages to create the image. The HVPS uses the 24V, and outputs the high
voltage for THV/MHV/BIAS.
Output high voltage is supplied to the following:
Toner
•
OPC cartridge
•
Transfer roller
•
SM 6-11
