Solutions

Diagnóstico rápido

The SC120 error triggers when the carriage fails to find its start position. You may hear a clacking noise while the scanner attempts to move. If it doesn't detect the home sensor, the machine flags this error to prevent damage to the carriage motor.

Solución paso a paso

  1. Check for Obstructions: Ensure no clips or papers are blocking the scanning area.
  2. Clean Rails: Power off and clean the rails on which the scanner carriage slides using a lint-free dry cloth.
  3. Power Reset: Restart the printer to force the scanner to try and reach its home position again.
  4. Check Locks: Ensure no transport locks (common on new units) are hindering movement.

Prevención y mantenimiento

Avoid moving the printer while it is on. Periodic internal cleaning ensures dust doesn't build up on the rails, preventing friction. Using original ink is recommended for general internal printer health, though it does not directly affect the scanner.

Cuándo llamar a un técnico

If the SC120 error persists after cleaning and rebooting, the scanner motor or the drive belt may be broken or disconnected, requiring professional repair.
