Hello.

Just received a brand new drum units and changed that. 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. Please help if somebody had such experience. I think Developer unit is not so bad as well. Please help!!!

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.

I would check first developing units and developing rolers for cyan and black color.

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

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.

Well, you know what "assume" does Phil. Makes an "ass" of "u" and "me". Lol :cool:

Information given can be cryptic. So not the drums and not the dev tank on K and yellow and magenta does not show problems so not the transfer.
That leaves the laser unit?
