Pattern to record: Jams vary with the paper stack and improve with fresh sealed media.

Locate the feed stage

Record the tray and the position of the sheet’s leading edge when it stops. Pickup, separation, duplex return and fuser exit are different stages; a jam message alone does not identify which roller failed. One possible explanation is that paper shape and surface friction fall outside the feed design.

Feed-path checks

1. Note the leading edge position, inspect sensors and rollers and compare each tray.
2. Compare approved dry media stored flat and review environmental conditions.

Before inspecting the mechanism

Fuser areas can remain hot long after printing stops. Repeated testing with unsuitable media creates misleading wear symptoms.

Correct the confirmed cause

If the checks support this cause, replace the media and correct storage before mechanical repair. Verification should cover single and multi-page jobs, every tray, duplex if fitted, different paper weights and exit.
