HP 5L (C3941A) High-Voltage Power Supply Check, Toner Cartridge High Voltage Connection Points 1

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 7-5	High-Voltage Power Supply Check
	Checks	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.
