For any fuser error, the first thing that should be done is replacing the fuser. If the error still shows up after wards, it could be the LVPS (Low voltage power supply) or a board.

It's a critical firmware error. Try printing another job. If that one works, something is corrupt with the first job. Still failing remove any extra DIMMs from the formatter. Don't remove the one in slot J1. That's the firmware DIMM. try to print. If it works, reinstall the DIMM and try again. Failure = bad DIMM. You may want to try a firmware upgrade. If everything keeps failing you'll have to replace the formatter.
