This 5052ci with DF-7110 jams intermittently with a 6510.04.86.01.03, a DF exit sensor stay jam.

Jams indicate paper is feeding from drawer 4. Drawer 3 has the same paper loaded in it. I would have expected some 6510.03 jams. Maybe they are equally likely to happen if that drawer is used.

Destination is tray A, the stapling output tray.
