To continue turn off then on
A critical firmware error has occurred that
caused the processor on the formatter to
abort the operation.
This type of error can be caused by invalid
print commands, corrupt data, or invalid
In some instances, electrical noise in the

specific software programs.
Sometimes, the formatter itself is at fault,

You need to get a technician in. The code is suggesting the formatter board.
Note that make sure that the technician (or you if you are replacing it) that once you replace the board and turn on the machine, don't do anything for about 10 minutes. No printing, nothing. Take out the network/usb cord out to prevent anyone from printing. The reason is that the NVRAM (memory) is updating the new board with your information. If anyone prints (whether from a computer or a configuration page) then it will interrupt the update and you will get the same error again.
