HVPS Board
The HVPS board creates the high voltage of THV/MHV/Supply/Dev and supplies them to the de-
velopment system for making best quality printing image. The HVPS part takes the 24V and out-
puts the high voltage such as THV/MHV/Supply/Dev, and the outputted high voltage is supplied
to the toner, OPC cartridge, and transfer roller.
(a) Transfer High Voltage (THV+)
- Input Voltage: 24 V DC +15% / -10% (21.6V~27.6V)
- Out Voltage: +1300KV 1.5% (200 Load)
- Out Voltage Trigger: 6.5
- Input Voltage Variation: +5%
Load Variation: +5%
- Out Voltage Rising Time: 100 ms Max
- Out Voltage Falling Time: 100 ms Max
- Transfer Variation Voltage on Environment Variation: +500 V ~ +5000V
- Control Method on environment: THV-PWM ACTIVE, transfer Active signal, of environment
sensing voltage is input and get feed back current, and recalculate it to resistance.
- Control method on transfer output voltage: It is controlled by changing its duty of THVPWM
Signal as follows. 10% Duty: +500V, 90% Duty: +5000V
