We have seen this issue when the mylar on the registration sensor assembly gets damaged. If you open the right door, the sensor assembly sits just below the transfer belt slot and pivots down to allow removal of the transfer belt. The top edge of that assembly has a mylar strip on it and we have seen instance where the mylar gets bent and then drags on the belt, creating the issue you are seeing. Photo below was from one of our clients, but the defect was on right side. I trimmed the bent side off two years ago, still running.
