High Voltage Power Supply (HVPS) Removal
1 Remove the Toner Cartridge and PC tray.
2 Lay the printer on its left side. (Place a cloth under the printer
to prevent marking the cover.)
3 Remove the (2) screws that hold the HVPS in place (see
Figure 6-19, callout 1).
4 Release the (2) latches that hold the High Voltage Power
Supply (see Figure 6-19, callout 2).
5
Pull the HVPS straight away from the printer to clear its
locator pins and to prevent damage to the HVPS connectors.
6 Remove the HVPS from its housing by releasing the (4)
retaining clips that hold the PCA in place.
Note
Run a printing self-test after replacing the high
voltage power supply. If the printer prints solid
black pages, the HVPS may be seated incorrectly.
Repeat the installation procedure, being careful to
align the high voltage connectors.
