    Re: Bizhub C368 fuser noise

    I have a lot of these in the field. I have dealt with fuser noise on several of them. Majority of the time it is fuser related. A handful of times it has been fuser drive related. In that case I just replace the drive unit as a whole. It may seem lazy but if I'm going that far in , I'm not taking chances. It was a nightmare at first but now I have it down to about 1-1.5 hour job total. Not too bad.

    This may be a coincidence but I have had very good luck diagnosing this using the following procedure.

    Run 45-1 load check to run fuser....run 45-1 in both pressure and retracted states (45-6 and 45-7) When the fuser is the culprit the noise will appear in both conditions.

    When the culprit is the "fuser drive" the 45-1 noise only happens in one of the 2 conditions (45-6 or 45-7, I honestly cant remember which one) but point is if its noisy in both its fuser, when it goes away from changing conditions its drive.

    I have only had like 3 drive units be the issue so that could be a coincidence.... but all 3 had that exact symptom in load check. If anyone else runs into it let me know if I am correct.

    Very useful information, Thanks MVP.
