Tray 3 has jam 1730 on 2 sided copies only. Single sided copies are fine. Replaced the clutch behind the black pullout transport tray. Bent the tray 3 sensor underneath the plate with the 2 screws down about 2mm. Replaced all feed components. Registration rollers turning smoothly not stiff or binding. Fuser and all consumeables are current and not overdue. Still gives that duplex jam code of 1730 but only from that tray. Suggestions appreciated.
