    what is " the toner cartridge head "?

    have you got the page counts on ALL supplies?

    when were they install?

    how long have you had it?

    sometimes life % isn't that reliable due to age of the parts.

    how about uploading examples of the issue?

    are you an end user?

    Is the paper being fed LEF or SEF?

    This is a fault with drum, dev, x-fer belt or print head..If you were talking about a 20 year old machine I'd say go for it..but this is pretty new..My advice is to call a certified KM tech..Think you are going to be spending a large amount of money, but this is nothing compared to how badly you can break it trying to DIY..E

    I dont want to DIY, Just want to understand what might be the problem, have already called for a technician. just dont want to waste a lot of time keeping the machine shut..loosing business.
    i am a mechanical engineer by academics. so always thrive for problem solutions and knowledge.
    Thanks for the reply.

    Since the yellow bars are through the voids and at about drum interval, I'm going to take a WAG that it fed SEF (short edge feed) and that you've got a primary charge loss situation. Most likely you'll have to replace the yellow imaging unit.

    But first: Confirm that this page was printed LTR-R, SEF. =^..^=
    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.
    5) You are the person onsite. Only you can make observations.
