Common causes

  • 1Mechanical blockage: Dust or debris interfering with carriage movement.
  • 2Home position sensor failure: Sensor does not detect the end of the rail.
  • 3Motor malfunction: Internal motor gear slippage.
  • 4Cable connection: Loose or damaged data ribbon to the scanner board.

Solutions

Diagnóstico rápido

The SC120 error is triggered when the scanner unit fails its initial diagnostic test. You may hear mechanical noise inside the scanner lid as it tries to initialize.

Solución paso a paso

  1. Check Obstructions: Ensure there are no foreign objects inside the scanner area.
  2. Manual Move: Power off the device and gently slide the scanner carriage to verify it moves freely.
  3. Power Cycle: Restart the device to reset the motor drive.
  4. Inspect Sensors: If the noise continues, check if the home position sensor is blocked by dust.

Prevención y mantenimiento

Regularly wipe the guide rails and avoid putting heavy items on the scanner bed. Proper ADF roller cleaning ensures document transport doesn't cause mechanical issues.

Cuándo llamar a un técnico

If the error remains after checking for obstructions, the scanner motor or the ribbon cable connecting to the mainboard may need replacement.

Steps to follow

  1. 1

    Check for obstructions

    Ensure the scanner carriage is not obstructed by debris and moves freely along its rails.

  2. 2

    Wipe the metal rails with a clean, dry cloth to ensure smooth carriage movement.

  3. 3

    Power reset

    Turn the printer off and on to re-initialize the motor sensors.

Frequently asked questions

The SC120 error signifies that the scanner carriage motor failed to reach its home position, often due to physical obstruction or sensor failure.

Yes, use a soft, lint-free cloth and mild cleaner. Do not apply liquid directly to the glass.

No, this is a mechanical error related to the scanning unit, not the printing engine.

Keep the scanner lid closed and the area clean to prevent dust from fouling the motor carriage.
