    Hello everyone, I have a problem with the color outputs (spots ?). On the other hand in black print only, I do not have the spots. Thank you for your help

    If I reply in English, would you have any understanding of my messages?
    I can try to use a translator, but the technical terms might become lost...

    Something is going on while the toner is on the image transfer belt. It could be something coming in contact with the belt (warped part dragging the toner) or it could be the ITB cleaning station failing in some way.

    you can see the streaks on the image are made of the primary colors, not a blend or mix of color

    Thank you for your answer. I found the lines on the drums which then is found on the belt and on the 2nd btr then on the back of the sheet passing only on the front.

    Since the problem has spread quite a bit it may be difficult to identify the initial culprit.

    my guess would be the drum’s smooth outer layer degraded so much they began to mark up the belt. Unfortunately every will need replacement at this point.
