                Have you tried another transfer belt?

                  try stopping the paper in mid cycle and you can see what device is causing the problem

                    It's still something black. Take a look at the drum ground or other charge contacts. You can apply conductive grease to the drum ground.

                    Do you have side voids where the bar crosses the page? The scanner creates voids even when there aren't any. If the the bar crosses the side voids it's charge related. =^..^=
                    If you'd like a serious answer to your request:
                    1) demonstrate that you've read the manual
                    2) demonstrate that you made some attempt to fix it.
                    3) if you're going to ask about jams include the jam code.
                    4) if you're going to ask about an error code include the error code.
                    5) You are the person onsite. Only you can make observations.

                      I am in the belief that it's the transfer belt. This model has issues with it

                        You know ... I had one of these transfer belt assy's apart for a broken gear in the cleaning unit. When I re-assembled it I missed one of the spring electrical connections at the front left of the primary belt unit. I got very similar bars like this. Then I noticed the spring just setting there in the paper clip pocket.

                        I wonder if that's important? =^..^=
