    MX7081 noise

    I have 2 7081's at the same account.

    Both have been installed within the last 3 weeks.

    Customer says the machines (both) will make a "moaning" noise, but only when sitting idle.

    During copy/print cycle noise is not happening. Only happens when machine sits idle. I have tried SIM's to activate all fans individually and together.... no noise

    Have done the same with motors.

    Any thoughts and/or suggestions welcome

    ** when this noise occurs, machine is idle and goes into an idle run state. Meaning its calibration or something due to temp and/or humidity change. I'm not sure what combination of items are rotating during this internal calibration

    I have heard this complaint on Sharps and it is usually the pressure release system of the fuser. When the cam turns it makes an awful "moaning" or "groaning" noise. You can test this cam via SIM and verify the noise is the same the customer is hearing.

    Or tell them both machine have the "Orgy" option installed....


    Failing to plan is planning to fail!!!

    Agree. I have seen(heard) this on Konica Minolta machines fusers.
    In any case noise record will be in great help here.

    Re: MX7081 noise

    I have had this groan on alot of the sharp models and just about always the blade that sits on the fuser heat web, most paper any more is dusty and
    it don't take many prints to get a buildup on it and make the groan at startup. I have been stretching the 2 small springs on the blade so they don't
    rub on the heat web so hard. That has cut down on the amount of noise calls I get. Hope this helps. Dan
