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.
