Troubleshooting steps
If parts are replaced or fixed in any of the steps listed below, attempt to verify printer functionality by turning the printer on and printing internal test prints. If functionality is verified, no additional parts should be replaced.
- Turn the printer off, using the main power switch located on the back of the printer.
- Check the power cable for damage and replace if necessary.
- Check the power cable connections.
- Turn the main power switch on.
- If no problem appears, attempt to verify printer functionality.
- If no power is detected, turn the printer off and continue with the remaining steps.
- After 10-15 seconds, turn the main power switch on.
- Listen for internal printer operations (fans, vacuum, or movement).
NOTE: If internal printer movement or noise is detected when the printer is turned on, use the work instruction Front Panel Display is Blank, Weak or Fading (bpp90219) to resolve the issue.
- If no internal movement or functionality is observed, replace the power supply unit (refer to pages 8-88 of the service manual).
- Following replacement, attempt to verify printer functionality.
- If the problem persists, replace the Main PCA and the HDD Controller (which connects to the new main PCA). Refer to pages 8-81, 8-85 of the service manual.
- Following replacement, turn the printer on and perform the Backup EEROM Service Utility (instructions below).
- Turn the printer off, then on, and verify functionality.
