Warning: Do not
replace the operator
panel and controller
board 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 J19. Turn on the printer, and check
for the following voltages at J19:
Verify ground at pin 5 for both the card and cable.
• If these voltages are correct, then 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, then replace the main motor gear drive which
includes the motor.
- If continuity does not exist on one or more of the wires, then call the next level of
support.
• If these voltages are not correct, then see “Controller board connector pin values”
on page 5-3 , or replace the controller board. See “Controller board removal” on
page 4-13 .
