    Exclamation Sharp Copiers Stuck in power loop

    I have a customer with 17 copiers in a building. 5 of which have the newer sharp user interface (2 Sharp MX-904s, 1 MX-7040, 1 MX-6240, and 1 MX-3140).

    The five with the newer interfaces have been giving me issues. Back in August the 904s, the 6240, and the 7040 started a power loop that lasted about 4 hours a day, for 3 days. The 3140 was not in the building yet.

    By power loop, i mean that the machines would just keep restarting anywhere between 3-6 min of use. We were able to get rid of this issue the first time by letting the machines sit unplugged for about 2 hrs. This problem only happens when the devices are plugged into the network.



    Yesterday NOV 9 we switch out a MX-3100 (Older UI) for a MX-3140 (New UI). When we try to set up papercut on the 3140, which is in a different location than the other 4 (same network), using the external applications settings, after the reboot, it triggers all 5 machines to start a power loop.

    The 3140 shows that it cannot connect to papercut and continues to power loop with the other 5.

    We can fix this by unplugging the 3140 and letting the other machines sit unplugged for about 2 hrs. but once we try adding the 3140 to paper cut the issue continues. We also don't know if this is a permanent fix for the other 4.

    The customer is very unhappy with what is going on right now. I called sharp and papercut and neither have seen this issue before, and I am waiting for a response. I am at a loss on what to do and am reaching out to you guys.


    Thanks,
    Nicolas Forsythe

    Network issue somewhere since as you say, This problem only happens when the devices are plugged into the network.

    It's been awhile, but make sure you are not using a WSD port, and turn off any ports not being used.

    Using PaperCut necessitates having the network connected at all times, for authentication. It makes me wonder if it's some sort of conflict between PaperCut and the MX-3140. Can you bring in a different model, even as a loaner, just to determine if that will resolve it? At least in the short term, that will take some of the pressure off of the situation. =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.

    We plan on putting a machine with an older UI there for now because we know it works. Thanks for the replies. I will post here if we find the solution.

    Latest firmware on all?

    Disable WSD and IPv6 on them devices and see if it helps.

    Had very similar situation.....Large car dealership....majority of printing was taking place from an AS400 mainframe......

    When ever a certain job from the AS400 hit the Sharps, it would cause a reboot of the copier

    You may need to do a packet capture to see exactly what is causing the issue.

    But first as someone mentioned, turn off all unused protocols and services. Turn off all unused ports in Security settings.

    I've also run into issue with Spiceworks (network monitoring software) and the Tandem copy feature, I believe port 50001

    Also make sure RARP is off under Protocol >TCPIP settings

    If that is still even an option
