Solutions

Diagnóstico rápido

If you hear abnormal clicking or grinding noises, it's a strong indicator of a faulty fan blade or bearing. Check the exterior intake vents first to see if lint or paper debris is causing a physical blockage.

Solución paso a paso

  1. External inspection: Check that the ventilation slots are not blocked by paper or dust.
  2. Forced restart: Power off the machine and wait until all fans stop before turning it back on.
  3. Internal check: If the error repeats, check if any fan is physically obstructed.
  4. Compressed air cleaning: Carefully spray compressed air into vents to dislodge particles.

Prevención y mantenimiento

Scheduled maintenance every 6 months is key. Keep your environment free from excessive paper dust to prolong fan motor life.

Cuándo llamar a un técnico

If the fan remains motionless after cleaning, internal hardware replacement is needed, which should be performed by a service professional.
