Solutions

Diagnóstico rápido

The 0x40 error triggers when the printer fails to detect the paper or the entry sensor is blocked. If the motor sounds normal but no paper is pulled, it is a traction failure.

Solución paso a paso

  1. Remove the paper tray completely from the unit.
  2. Inspect the input area for any scraps or torn pieces of paper.
  3. Clean the rubber rollers with a soft, dry cloth to improve friction.
  4. Align the side guides accurately to match your paper's width.

Prevención y mantenimiento

Fan the paper well before loading. Do not fill the tray above the maximum limit mark. Clean feed rollers every six months to maintain traction.

Cuándo llamar a un técnico

If the rollers continue to spin without grabbing paper after cleaning and clearing potential jams, the internal paper sensor may be faulty.
