Product Technical Overview
High Voltage DC Power
The high voltage power supply (HVPS) converts +24VDC power into the high voltages required
by the xerographic subsystem.
The INTLK +24VDC power supplied via the drive PWB enters the HVPS, is routed to the trans-
formers on the board, and is modified to the voltages required for charge, developer bias,
detack, and transfer.
Refer to:
• BSD 9.2 Charging and Exposure
• BSD 9.3 Development
• BSD 9.6 Image Transfer
The HVPS is mounted behind the drive PWB, refer to Figure 3.

Mode Remaining
Running Mode The data receiving/image creation/recording (printing) operation
mode
Ready Mode When the system can enter the Running Mode immediately
Low Power Mode The mode that reduces the power consumption more than the
Ready Mode
Sleep Mode* The mode that reduces the power consumption further more
