Transfer Belt is also changed and good, but still keeps printing stripes on the solid color. shuffling color drums but no reaction only Cyan and Black makes stripes.

    You have swapped drum units but the problem is still there. So issue is not with the drum units. It is cleared.

    Now come to the second point which is Transfer belt, you have replaced transfer belt unit and it is good. when it is new it would be best. You didn't attach snapshot of transfer belt unit's life. Problem can be with black and cyan transfer rollers inside transfer belt. High voltage unit can also be the cause of this problem.

    3rd point is Developing units if you have checked them, brush OK? "K" DV unit life is expired almost, but this is not the reason.

    Yep, looks like uneven pitch at 28 mm intervals. Definitely developing units.

    Like they said: developing units. OEM supplies? =^..^=
    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.

    As far as i know you cannot buy developing roller only. Its whole developing unit as you know it. There is no part number for this single part. You can take it from old developing units if you do not want to purchase new.

    If you want cheap you're in the wrong business. Or least sell Kyocera and it'll be under warranty.
