Error code appeared right after clearing a jam
A jam that is pulled the wrong way can knock a sensor flag or leave a scrap behind. Recheck before panicking.

- 1
Write down the exact code
The code tells you which subsystem is complaining — paper path, carriage or sensor.
- 2
Recheck the paper path
Open every door again and look for a torn scrap near the registration and exit sensors.
- 3
Check sensor flags move freely
The small plastic levers in the path should spring back. A dislodged flag triggers permanent errors.
- 4
Power cycle fully
Unplug for 60 seconds so the firmware clears latched jam states, then power on with all doors closed.
- 5
Stop if the code persists
A service-level code that survives all this means hardware damage — book a technician.
