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.
■ HVPS (High Voltage Power Supply)
• Transfer High Voltage (THV+)
- Input Voltage: 24 V DC +15% / -10%
- Output Voltage: +1300V±3% at 200MΩ load
• Charge Voltage (MHV)
- Input Voltage : 24 V DC +15% / -10%
- Output Voltage : -1350V±3% at 50MΩ load
• Cleaning Voltage (THV-)
- Input voltage : 24VDC+15%/-10%
- Output voltage : -1200±20% at 200MΩ load
• Developing Voltage (DEV)
- Input Voltage : 24VDC+15%/-10%
- Output Voltage: -330±3% at 50MΩ load
• Supply
- Input voltage : 24VDC+15%/-10%
- Output voltage : -530±3% at 50MΩ load
