High-voltage power supply check

The High-Voltage Power Supply PCA provides the necessary voltages for the electrophotographic processes. A method for verifying the high-voltage system is given in the table below.

Table 7-4 High-voltage power supply check

Check	Action
Toner Cartridge Connection Points	Visually inspect the three connection points on the underside, right
	end of the toner cartridge. If they are dirty or corroded, clean the
	connections. Use alcohol only. If damaged, replace the toner
	cartridge. (See Figure 7-5 below.)
High Voltage Connector Assembly	This assembly uses spring-loaded pins to contact the toner
	cartridge. (See Figure 7-6 on the following page.) Verify that the pins
	are not dirty or corroded and that the spring-loading action is
	functional. If the pins are dirty, clean using alcohol only; if damaged,
	replace the High Voltage Connector Assembly.
