Main motor service check
FRU Action
LVPS/HVPS
LVPS portion of board
Fuses that open typically indicate a faulty LVPS/HVPS.
Disconnect the power cable, and open the LVPS/HVPS enough to test the switch. The
switch will show continuity across the conductors with a meter when the switch is on. If the
switch is good, see “Dead machine service check” on page 2-19 for more diagnostics.
HVPS portion of board
Problems with the HVPS are exhibited in the print quality. See “Print quality service
checks” on page 2-24 for more information.

Controller card
Warning: Do not
replace the operator
panel and controller
card at the same time.
Each card contains the
printer settings. When
either of these cards is
new, it obtains the
settings from the other
card. Settings are lost
when both are new
and replaced at the
same time.
Turn off the printer, and unplug the main motor cable at J17. Turn on the printer, and check
for the following voltages at J17:
Verify ground at pin 5 for both the card and cable.
• If these voltages are correct, check the main motor cable for continuity.
- Remove the left side cover to access the connector on the motor.
- If continuity exists on each wire, replace the main gear drive which includes the
motor.
- If continuity does not exist on one or more of the wires, replace the motor cable.
• If these voltages are not correct, see “Controller card connector pin values” on
page 5-2, or replace the controller card. See “Controller card removal” on page 4-13.
