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. 21 Figure 96.
