Solutions

Diagnóstico rápido

The error C460 happens during warm-up or high-volume jobs. If it occurs immediately after powering on, a sensor or fuser lamp is likely compromised.

Solución paso a paso

  1. Power Reset: Turn off the main switch and unplug for 15 minutes.
  2. Thermal Inspection: Check for burnt paper or debris around the fuser area.
  3. Ventilation Check: Ensure rear exhaust fans are clean of dust buildup.

Prevención y mantenimiento

Keep the printer away from walls that obstruct exhaust flow. Clean air filters periodically. Using genuine toner is vital, as aftermarket toner often deposits non-conductive residue on sensors, leading to thermal errors.

Cuándo llamar a un técnico

If C460 persists after a power reset, professional servicing for the fuser unit (lamp/thermistor replacement) is mandatory.
