Tilley4 is on the mark. We have had this happening on many of the 2050s also. We end up replacing the white shift rollers in the left side door and lower the fuser temps, if you look closely at those white feed shift rollers, the two center ones are probably deteriorated pretty good. We also experience less build up on the heat roller in the fuser. One of our techs has also hot wired one of the fans to run constantly to help out with the white shift rollers to keep from deteriorating.
