how to reset the fusing unit c451/c550/c650 series
November 16, 2011
Turn off the main switch !
Remove the fusing unit from the machine (2 screws)
Remove the plastic cover (tw.front of the machine) of fusing unit (3 screws).
In that area- under plastic cover - you’ll be find a lot of wires and harness.
Look carrefully- and see there a green resistor inserted on one of the wire.The resistor is covered with a transparrent cover (tube).
Cut this resistor and put in the same way (replace-it) with a fuse (max 0.08A).
Now replace the cover, and the fusing unit in machine.
Turn On the main sw.
Good luck !
And keep in touch !
