IMPORTANT: All requests for NVRAMs must be approved by the SSD Hotline and a problem ticket generated. If a request is received without an established problem ticket number the request will be denied.
Before replacing the NVRAM, thoroughly troubleshoot the problem. The NVRAM should be replaced only as the last resort. Many times replacing it DOES NOT solve the issue and, when it does, only a setting in the NVRAM may have caused the problem.

NVRAM. Keep your firmware handy.

Always worth while to look at the cables between the control panel itself and the MFP....there is a board under the scanner unit (behind the CCD), PWB-C which can also be at fault for some problems with the panel. Check the ribbon cable and the heavy interface cable at both ends...sometimes oxidation is enough to cause issue. See attached image, red circled items....or for that matter, the C-board itself may have failed.
