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.
