Solutions

Diagnóstico rápido

If you hear a sharp 'click' noise followed by the 0x5A error, the carriage has collided with something or the motor has failed. Check for leftover paper scraps in the purge area or if the timing belt looks loose.

Solución paso a paso

  1. Inspection: Turn off the printer and gently move the carriage side to side.
  2. Cleaning: Clean the slide rail with a clean, dry cloth to remove adhesives or dust.
  3. Cables: Verify that no flat cables are loose and snagging on movement.
  4. Reset: Reconnect and allow the printer to try finding its starting position.

Prevención y mantenimiento

Keep the equipment clean of dust. Friction on the rail is the main cause of motor wear. If the printer feels slow, it is time for professional rail cleaning.

Cuándo llamar a un técnico

If after cleaning the rail and verifying the carriage slides without resistance the 0x5A error persists, the stepper motor is damaged and must be replaced by a qualified technician.
