    MX-B557P error 120.82

    We are getting an error 120.82 on this machine.

    Fuser has been replaced, fusermotor has been replaced, connections checked, still goes into errorstate.

    Sometimes it starts up normally, but then after a few minutes goes into error again.

    FW is latest.

    Is there a way to test if the main board is the problem without actually replacing it with a new one? Since you can not swap this from another machine...and a new one costs as much as the printer itself...
