High-Voltage Power Supply Check
The High-Voltage Power Supply circuitry, on the DC Controller
PCA, provides the necessary voltages for the printer’s
electrophotographic processes. A method for verifjring the
high-voltage system is given in the table below.

ACTION
1, 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. Clean using alcohol
only. If damaged, replace the toner
2. High Voltage Connector Assembly,
The High Voltage Connector Assembly
mounts on the DC Controller PCA and uses
spring-loaded pins to contact the toner
cartridge (see Figure 7-2 for locations).
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 (see
lC~apter 6 ~or procedure). -
