Paper jam error that won't clear
No paper visible but the jam error stays? A torn scrap or a stuck sensor flag is almost always the cause.

- 1
Unplug and open every door
Front, rear, duplex unit and the document feeder on top. Shine a torch into the paper path.
- 2
Look for torn scraps
A thumbnail-sized piece near the registration rollers keeps the sensor triggered. Remove it with tweezers.
- 3
Check the sensor flags
Small plastic levers in the paper path should spring back freely. If one is stuck or broken the jam error persists.
- 4
Clean the rollers
Wipe the pickup rollers with a lint-free cloth dampened with water. Dusty rollers cause repeat jams.
- 5
Power cycle to reset the error
Unplug for 60 seconds so the firmware clears the latched jam state.
