    Re: 654e jams with no jam code, forces reboot

    Thanks all, feel free to drop in any thoughts as they come to you.

    I am going back, since I ordered the interlock switch. I will definitely check out the duplex door sensor and print out an MML.

    It jams prints or copies, any cassette.

    Here is just a photo of the screen and no corresponding jam code on the screen or in the history.

    Does it jam single sided or only double sided? Does it always show the same locations even if you use tray 1, 2 or the bypass?

    Does it pass any paper? What happens if you remove the paper dust cleaned and close the side door?
    Whatever

    Just for the record I haven't replaced an interlock switch in over 20 years so sorry to say I don't think that's your problem.

    +1 on that although I don't have your vast experience with KM, never had even to thought about changing interlock switch on KonMin office machine.

    I am hoping your brains and any good will my modest contribution has made can help me in my predicament.

    For starters, I am not a Konica tech, nonetheless I have a machine to service. I have the manual but no access to Knowledge Base, firmware or tech support.

    I have a 654e with frequent jams up the right side door. No crunching of paper & not always in the same place. What's odd is the jams are not being recorded in the Jam History section of the Service Mode. And after all the paper is cleared, I need to reboot the machine to get rid of the jam message on the screen. There are also no Trouble Codes recorded.

    I forced a tray jam by poorly loading paper and it does record those jams.

    I forced the door open during operation and it doesn't record those type of jams.

    So I am thinking I have an electrical issue, perhaps a door interlock switch. What leads me away from the door interlock is that I have to reboot the machine to clear the jam message. I'd think a flaky interlock would reset after a few good door closings.

    So that's that. If you need any more info I will try my best to provide it.
    Have you done a trouble reset yet?

    jam + reboot, might have been triggered by a bad print job IIRC

    User tmmdmmm was correct! And thank you all for your help.

    I actually got very lucky today. When I went to print out the Management List, as instructed, the machine went haywire and flashed repeatedly to close a door. If you look close at the video you can see it's telling me to close the duplex door.

    And sure enough, the door sensor was caked in paper dust. Cleaned it up and presto.

    Door Open - YouTube Sorry it's in portrait mode!

    Weird...

    Good job. Was suspecting the duplex door. Glad it got resolved.

    Good to know and thanks for following up. This is one I will "try" and put into my old brains memory bank. I still have around 10 of this model I service so might just go ahead and clean that duplex sensor when there for something else.

    If you didn't already you may want to give tmmdmmm a positive Rep Power point. click on star at bottom of his post.
