With the printer on, verify +24 V dc on pin #7 at J10 on the controller card assembly.

• If the voltage is correct, check the main motor cable for continuity.
  • If continuity exists on each wire, replace the main motor.
  • If continuity does not exist on one or more of the wires, replace the motor cable.
• If the voltage is not correct, verify +24 V dc on pins #1 and #2 on J17.
  • If voltage is correct, replace the controller card.
  • If the voltage is not correct, check the LVPS.

Note:
Always check printhead alignment after replacing the controller card assembly. See “Printhead assembly adjustment” on page 4-2 for hardware alignment of the printhead.

If the buttons do not depress or click when pressed, replace the operator panel.
If the operator panel does not illuminate, turn the printer off and unplug J5 on the controller card. Verify pin #4 is ground. Turn the printer on and verify +5 V dc on pins #2 and #5. Also verify +3.3 V dc on pins #6 and #7.

• If any of the voltages fail, replace the controller card. See “Controller card assembly removal” on page 4-50.
• If all of the voltages are correct, verify the continuity of the operator panel cable. If the cable fails continuity, replace it. See “Operator panel cable removal” on page 4-20.
• Otherwise, replace the operator panel. See “Operator panel assembly removal” on page 4-22.
