Kyocera TASKalfa Pro 15000c Error C5800: Fan Failure

The Kyocera TASKalfa Pro 15000c error C5800 triggers when the system detects that one of the cooling fans is not rotating at the correct RPM. This warning is a vital safety measure to protect internal circuitry and ink quality. If this error appears, airflow is compromised, which can degrade the performance of your production machine. Follow these steps to verify your ventilation status.

Common causes

  • 1Excessive dust accumulation physically blocking fan blade rotation.
  • 2Electrical fan motor failure due to end-of-life.
  • 3Accidental disconnection of the fan cable after a previous intervention.
  • 4Faulty RPM monitoring sensor providing false low-speed data.

Solutions

Diagnóstico rápido

The C5800 error manifests as a touchscreen lock-up following a loud or intermittent fan noise. Often, the issue occurs in machines operating in dusty environments, causing residue to accumulate on fan blades.

Solución paso a paso

  1. Clear Vents: Ensure no ventilation grids are obstructed by walls or furniture.
  2. Power Reset: Turn off the machine completely for 10 minutes to allow natural cooling.
  3. Spin Check: Listen to see if a fan attempts to start but sounds stuck due to dust.

Prevención y mantenimiento

Vacuum the external grids monthly and ensure the working environment does not exceed 30°C. Preventative dust cleaning extends fan life and avoids critical blockages.

Cuándo llamar a un técnico

If the C5800 error persists after cleaning external dust, the fan motor might be burned out or the RPM sensor disconnected. Replacing internal fans involves dismantling panels, which requires a technician.

Frequently asked questions

This code indicates a failure in one of the internal cooling fans, which could lead to critical overheating.

You should stop using it; overheating can permanently damage the logic board or the ink injectors.

Non-genuine consumables may generate fine particles that clog ventilation filters.

Keep the area around the device clear and perform monthly external dust cleaning with gentle compressed air.
