    TaskAlfa 4500i

    This machine makes a whining/humming noise when copying. The noise will continue for a few seconds after the copy/print is made. Sometimes it gets quite loud and other times you can barely hear it. I checked and the machine is in the silent mode. I am thinking it may be the fuser has anyone else had this problem? Thanks in Advance

          Idle rollers, fans, clutches, drum, bushings, gears.

          U030, U031, U037, U243 (DP) .

          General TB 91. Junction wire to cheat main innerlock which can help troubleshooting a noise.

              Fan, put your hand in the back and press, back cover pushed in?

                  Fusers on this this model can get very noise from time to time. Test the fuser from maintenance mode. And Replace if needed.
