Pattern to record: The feed motor turns but the first sheet remains in the tray.

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 the roller surface has become smooth and cannot develop enough grip.

Feed-path checks

1. Note the leading edge position, inspect sensors and rollers and compare each tray.
2. Inspect and compare the pickup surface and feed timing with clean supported media.

Before inspecting the mechanism

Fuser areas can remain hot long after printing stops. Aggressive solvents can swell rubber and make feeding worse.

Correct the confirmed cause

If the checks support this cause, clean only if appropriate or replace the worn roller. Verification should cover single and multi-page jobs, every tray, duplex if fitted, different paper weights and exit.
