Lines on prints

[brancas]

Hey guys. I have an FS C8520 giving off black streaks. Transfer belt was changed. A few months after problem reoccured. Transfer belt is the issue. What can cause the transfer belt to give that problem. I do not have a sample now to show. But u can see the same pattern on the printed docs as well as the belt. Irecently installed a used working belt and it worked for a few weeks. I also changed the drum and the black developer which was looking worn. Any suggestions?

check your waste toner coming out of the transfer belt and to the bottle.

I have seen this a few times.
It is the waste toner drive assembly gears failing.
