Versant 280 White Banding Mottle

Has anyone experienced these white mottle lines before on a Versant 280? See photos below. I've had 2 Xerox engineers out now and can't seem to find a solution.

I've never had this issue and I'm not sure what the solution would be. You may want to look at the drive coupling that connects the transfer belt to the flywheel. I understand that they can get broken and cause all kinds of issues. Pull out the drawer and look to see the plastic coupling that connects to the flywheel. I can post a picture of it on Monday if my description wasn't helpful.
