    Bizhub C250i annoying noise

    Hello friends!
    I have one Bizhub C250i with strange noise (mouse like).

    Can someone tell me what can cause this sound and how to get a rid of it?
    Thanks in advance!

    When it's squeaking, does it stop when you open the front door?

    It's the exit rollers.

    Thanks for the reply!
    Sorry to ask maybe a stupid question, but I didn't understand where exactly to apply the lubricant - on the rollers, on the shaft under every roller, or in the ends of the shaft?

    the exit rollers can be responsible as well as the waste toner hopper.
    in the case of the hopper, apply PTFE lubricant to these areas

    I normally strip the unit down completely and lubricate everything

    For this particular model line, the shaft where the lower idler rollers ride. The ones along the bottom in my video. If you run the exit rollers like mentioned you can lubricate them and work it in.
