We replaced the ITB belt, drive gear, swing plate, did not fix until we went into Sevice Mode 2 and cleared REGIST, performed Gradation Quick, then Full Adjust - perfect pages. Now it is reported the problem is back. Any thoughts? I doubt the pattern reader would be causing this issue but not sure. 1mm shift in colors for paper travel direction. No skew, vertical offset. Have switched with another ITB unit, same issue.
