High-voltage power supply check

The high-voltage power supply PCA provides the necessary voltages

for the electrophotographic processes.

To check the print cartridge connection points

Turn the print cartridge over and visually inspect the three connection

points on the ends of the print cartridge: drum ground (callout 1),

charging (callout 2), and developing roller (callout 3). If they are dirty

or corroded, clean the connection. If they are damaged, replace the

print cartridge.

Note Use only isopropyl alcohol to clean the connections.
