Try initalizing the Harddrive if that doesn't work.
Try replacing the scanner controlboard or the DC controller.
Or if the MFP is in a dusty room try cleaning the lenses and mirrors in the scanner unit first

The pin for this specific machine should be 11434506.
If that doesn't work you must cold reset the machine.
Turn it off the machine.
Turn machine on hold 6 down until the memory count is done and all 3 lights are on release 6 and use 3 to arrow up to cold reset and press 6 "acts as the enter button"
3 works as arrow up
9 works as arrow down
6 works as the Enter button
