Have you performed a stop-test? Is the defect happening before the fuser? Visible on the belt?

Put the defect at the 2nd transfer roller and see where the lead edge of the paper is and look in that area for something that will either stall or grab the paper at a different speed.
Check the transfer cleaning unit also.

Which side of the paper is the lead edge and which one is the trailing edge? Does the problem happen with different paper weights?
