High Voltage Power Supply Assembly

The High Voltage Power Supply Assembly provides the necessary voltages for the printer’s electro-photographic processes. The +24B VDC supply is used to power the High Voltage Power Supply Assembly. A summary of the major components of the high voltage system, is given in the table below (see Figure 7-18 for High Voltage PCA layout).
