Fuser unit has failed.

C6400 indicates that the engine board is not recieving the correct signal.

I would suggest that you turn off the machine and ensure that the cable that runs from the document feeder at the top rear of the machine into the connector on the rear of the machine (if fitted) is securly tightened.

You can also try turning the machine off at the wall for 10 minutes.

If this fails you will need to call out a technician.
