A local technician here Xerox he works for said to change the duolexing upper chute assembly.
We have already take on those parts but the motor in the back we did chabge the duplex motor in the back. We did change the gears and the belt it will work for some time then stop again. You know it will stop when the machine starts up then you hear the loud grinding noise coming from the left side of the printer.
And paper jams in same place when we cleaned it one time started jamming in the chute then I played with the belt a bit cause it would get real tight and then it will loosen up and work again but now I play with it rocking it front and back nothing happens
