Solutions

Diagnóstico rápido

If the machine fails the initial boot-up heating phase, error C480 appears. This protects the unit from attempting to process toner in a cold, non-functional fuser.

Solución paso a paso

  1. Power cycle: Turn off, unplug, and wait 45 minutes.
  2. Restart: Reconnect and restart. If C480 occurs, technical repair is needed.
  3. Avoid manual tampering: Do not open the fuser area.
  4. Call for service: This is a hardware fault in the thermal path.

Prevención y mantenimiento

Ensure the machine is located in a temperature-stable environment (15-30°C). Large industrial copiers perform best when not subjected to extreme ambient cold or heat.

Cuándo llamar a un técnico

C480 requires a technician to check the fuser lamp and thermistor resistance, as these are non-user-serviceable parts.
