[raulblanco]

Hi
I have a c650 and generates noise when gets paper trays 3 and 4 other trays no noise. I changed the motor m26 since it is common to trays 3 and 4 but still making the same noise. We have also changed the wheel modules of these trays. It has happened to someone?
thanks

thanksHave you had a look at the drive gears at the back of the machine behind the trays..they are where the noise normally comes from, toner and dev from the black IU falls down the back of the copier into this area and the gears clutches etc get covered and wear badly causing the noise!
