Hmmm.....
Turn it off.... (both switches) then turn it back on, but while doing so hold down the utility key. When trouble reset shows up on the screen hit that. Then reboot.
Let us know.

will the machine allow you to re flash it, also can you get into tech rep made and check sensors, run test on doc feeder or finisher?

try to re flash here are some other known problembs

The Start key is flashing amber and the machine will not go to the ready state.

Solution

PROBABLE CAUSES:
1. The PWB-REDB (Scanner Relay Board) has failed.
Replace the Scanner Relay Board (p/n A00J H00A 02).
Note : This board is also referred to as the PWB-IF board or the REYB/SCAN board.
2. The PWB-MFPB has failed.
Replace the PWB-MFPB (p/n A00J H020 07).



The blue and orange scanner lights are illuminated and the START key is solid amber. The machine may have been subjected to a power surge.

CAUSE: Failure of MFP board and NVRAM.
SOLUTION: Replace the MFB board and NVRAM.
