Solutions

Diagnóstico rápido

If you hear a grinding noise from the top of the printer when you power it on, the SC120 error is likely occurring. This confirms a mechanical inability for the scanner to initialize correctly.

Solución paso a paso

  1. Power down the unit and unplug it for a clean restart.
  2. Inspect the scanner glass and the area underneath the cover for any obstructions.
  3. Clean the carriage track if there is noticeable debris.
  4. Restart the system to allow the motor to attempt a new home position calibration.

Prevención y mantenimiento

Do not overload the scanner with heavy objects. Regular cleaning of the glass with non-abrasive cloths keeps debris from entering the internal housing.

Cuándo llamar a un técnico

If the motor continues to make loud sounds or the error message doesn't go away, the scanner motor or the drive belt is likely broken and requires professional service.
