8.2 Overview

8.2.1 Mechanical
There are two power supplies in the printer: The Low Voltage Power Supply (LVPS) and the High Voltage
Power Supply (HVPS).
8.2.2 Electrical
The LVPS provides +5 VDC, +12 VDC, +24 VDC, and –12 VDC for operation of motors, logic boards,
floppy disk drives, and the control panel.
The HVPS provides –400 mA for the charge corona, –720 VDC for the charge grid, +4,600 VDC for the
transfer corona, and –550 VDC for the developer.
Note that the fuser lamp is powered directly from the AC supply (115 VAC or 230 VAC) and not from
either of the internal power supplies. However, on/off control of the fuser lamp is performed at the LVPS.
