Diagnóstico rápido

The 31.01 code appears as a tray error. If you open the lower compartment and find crumpled paper or small fragments blocking the sensor, you have confirmed the source of the jam.

Solución paso a paso

  1. Open tray: Remove the paper tray completely to inspect the main feed area.
  2. Remove jam: Gently pull out any jammed paper, ensuring no small scraps remain behind.
  3. Clean sensors: Use compressed air to clean the paper entry sensors located near the rollers.

Prevención y mantenimiento

Always use fresh paper and keep it in a dry environment. Clean feed rollers with a soft cloth and isopropyl alcohol to maintain grip. Avoid overloading the tray capacity.
