Solutions

Diagnóstico rápido

If the display reads C0140, the printer is blind to the presence of the paper tray. Look into the cassette slot; is there any torn paper or loose labels covering the plastic sensor lever?

Solución paso a paso

  1. Pull the paper cassette all the way out of the printer.
  2. Inspect the cavity for dust or debris; clear any found with a dry cloth.
  3. Ensure the paper size guides are not set wider than the paper itself.
  4. Slide the cassette back into the printer and check the panel for detection.

Prevención y mantenimiento

Insert the tray smoothly without slamming it into the housing. Ensure paper guides are locked. Cleaning the internal area around the sensors once a month helps maintain reliable detection.

Cuándo llamar a un técnico

If the tray is correctly inserted and the sensor is clean but the error remains, the tray detection switch has likely failed and requires replacement.
