Control panel removal

Critical information for controller board or control panel replacement

• Control panel
• Controller board

To replace a component and to test whether the problem is resolved:



1. Replace the affected component.

   Warning—Potential Damage:  Do not perform a Power-On Reset (POR) until the problem is resolved. If a POR is performed at this point, then the replacement part can no longer be used in another printer and must be returned to the manufacturer.



2. Enter the Diagnostics Menu. The Diagnostics Menu allows you to temporarily use the replacement part.

   Warning—Potential Damage:   Some printers will perform a POR automatically if the Diagnostics Menu is not opened within five seconds. If a POR is performed at this point, then the replacement part can no longer be used in another printer and must be returned to the manufacturer.



3. Use the Diagnostics Menu to test the replacement part. Do a feed test to check if the problem is resolved.

   • If the problem is not resolved—Turn off the printer, and then reinstall the old part.
   • If the problem is resolved—Perform a POR.
   • If NVRAM error occurs during the replacement, go to NVRAM mismatch failure service check
