    BizHub C558 Misfeed Detected on Scan&copy, but no misfeed. Error Code: 66-02

    Hello - Having the following issue on a BizHub C558. When using the document feeder for scanning or copying a single or multiple sheets, we are receiving misfeed detected error code: 66-02. We don't receive the error until the document feeder has finished scanning all of the pages. The document feeder appears to be functioning properly, no jams/misfeeds have occurred. However, we are still consistently receiving the error.

    In order to reset the error, we open and shut the top compartment of document feeder. It will not complete the job because it request to reload originals and the error re-occurs.

    Almost seems like the machine is not sensing the paper exiting the feed.
    Has anyone experienced this issue?

    Thank you for any advise or guidance!

    The obvious thing to me, would be a dirty sensor, so it thinks that there's still paper there
    Tip for the day; Treat every problem as your dog would.....If you cant eat it or f*ck it....then p*ss on it & walk away...

    good day
    The first thing I would do is see the parts counter
    the separation roller and feed roller last 300K
    Then try scanning but with the thin paper option so the scanning speed goes down
    If the jam code does not occur there
    Then the problem would be in the separation roller
    It would be necessary to rewrite the fw to a current version


    Regards.

    Grab an air can and blast the hell out of every single sensor in the paper path. clean the rollers with IPA and try again

    The fact DF has no physical Jams, doesn't mean it's working properly.
    Did you follow manual and test after separate sensor (PS4) in I/O check?

    WalterJ - Thank you for the response. The machine is pretty new, the total count is only 7k. I just tested with thin paper selected and got the same misfeed error.

    Kingarthur & Synthol - Thank you for the responses. With dry compressed air, I blew out the document feeder and sensors. All rollers & sensors look very clean.

    Tsbservice - Thank you for the information. We do not have the service manual for this unit. I will see if I can find one and try your suggestion.

    Sounds like the document feeder empty sensor is dropping too slow..The sensor must be working or you would not be able to start a ADF feed, but as the last sheet goes through the sensor flag is not dropping into its empty position, the ADF thinks another sheet is present and, of course, no paper went through, so it must be jammed. E

    On the C558 there isn't a sensor flag, on this RADF the tray lifts up to the rollers, unlike the smaller machines, where the rollers come down, those RADFs have a magnet on the actuator to hold it in position, when these magnets fall out, you get constant J66-02 when the last sheet has gone through, on the C558 there's a "reflective" sensor in the infeed paper tray....that's the sensor that needs to be looked at, it's either dirty or faulty, or open up the top cover and check that there's nothing stuck to it, that the sensor may be picking up

    Once it has taken the paper, do the rollers still spin?


    Sometimes, during transport, some sensors may like off and give incorrect values.
