Looks like black image unit or transfer belt need to be replaced. What do the consumable life counters look like?Originally Posted by kombo2
+1 on black IU.

Take the TBU out of the machine and turn by hand if the marks disappear off the belt then its black image unit
Thanks for the suggestions, i should have mentioned that i have replaced the black imaging unit just a couple of weeks ago because of another issue (that was fixed by the replacement), so i hope it is not the imaging unit again.
What was another issue?

I think you even helped to solve it : )
By the color of the stripes and the distance between them, I would say that it is a problem with the transfer belt, check manually
I agree.
