[Mukasa]

i have a xerox 700 with a code 077-311 that is really challenging me .It talks of the inverter system of which we have changed from a working machine.
when you test the inverter nip motter in diagnostic it makes a vibrating noise and the motor does not turn .I have also changed the iot driver no result.
what can i do.

Hi My friend,
thanks for the tips .
I have gone ahead and replaced the exit inverter assembly and IOT driver Pwb from a working machine but the fault didn't clear,
the inverter motor still make vibrating noise while warming up with fault code 077-311.
