Take Apart High-Voltage Power Supply - 109
voltage power supply to Apple.
1 Turn over the printer.
2 Remove the two screws that secure the high-voltage
power supply to the bottom chassis.
3 Note: There are three hidden contacts and a pin
connector that mate with the high-voltage connector
block. They may cause slight resistance when you are
performing this procedure.
Release the two flex tabs and pull the high-voltage power
supply out of the printer.
Replacement Note: Make sure that the contacts and
connectors are firm. Run a service test page after replacing
the high-voltage power supply. If you get a solid black page,
you have probably not seated the high-voltage power supply
correctly.
