HVPS
Check the following voltages at
J10-8 on the engine board:
Printer Idle
J10-8 measures 0 V dc
Printer Printing Test Page
J10-8 voltage changes from 0 V dc
to +4 V dc
If the voltage does not vary, check
the continuity of line J10-8 in the
front cable harness. If there is no
continuity, replace the cable
harness. If there is continuity,
replace the HVPS. If this does not
correct the problem, replace the
engine board.
Turn the printer off and check the
resistance between J10-7 and
printer ground. The resistance
measures approximately 0 ohms. If
incorrect, make sure the engine
board is mounted correctly and
securely grounded. If correct,
replace the engine board.
