    Kyocera Taskalfa 3252ci background and error codes

    Hey all

    Having a strange problem with one of our machines, attached are samples.
    There is background on the prints, appears to be all colours and if you look carefully there is also some repetition which is 94mm apart.
    It is also throwing a few error codes that don't display but are being logged.

    7200 - Broken Thermistor K
    7241 - Broken Thermistor Belt

    7614, 7611, 7620 K and Y bias calibration read and Auto colour registration error (I thought these are just due to the terrible quality of print)

    I have inherited this job from another tech, very possible it is tech induced.

    Things that have been tried:
    Drums, Devs, Belt unit, main HVT.

    None have made any difference and the fault appears to be getting worse the more pages that are printed.
    I have cleaned checked all the contacts between hvts and units and also all earths are clean and making contact.

    Would appreciate any thoughts on this fault,
    Thanks guys

    Might sound stupid but this isnít one of those cases where the customer has put the waste toner bottle in the black toner slot is it?

    are the waste exits of the drums or belt plugged? We have had a couple of pluggages of the waste conveying auger/chute near the waste bottle and a waste bottle not turning(deformed housing). They were all really noisy/grind-y.
    We have also had customers somehow re-reuse the black bottle/waste and contaminate the black dv.
    I'm seeing yellow as well as black background on there... is there any chance grounding is somehow lacking?

    This fault has been repaired, I don't know why all responses to the thread have vanished including the fix.
    Admins?

    I was hoping the rest of this thread would magically appear just like it magically disappeared!

    If you have this fault you'll notice drum counts haven't cleared and if you switch U100 DC Auto Adj to OFF the fault will vanish.
    The fix was new drums, but I had to switch the machine on with no drums and allow it to error before the drum counts would clear on the machine.
    The drums I fitted without doing this had the count of the previous drum written to them, and they were cactus... backgrounding and high count despite being brand new. So they've all gone back to Kyocera who seem to think this was all caused by fitting drums without switching the machine off.
    The techs involved when this machine was on the field deny this.

    There was a response to this thread of another tech in america who's encountered this exact fault, so it's one to watch for.

    Cheers

    If thatís the case Kyocera need to get there finger out and update the firmware to resolve this issue because you shouldnít really have to power off before changing a drum.
