Solutions

Quick Diagnosis

Error C0003 indicates the fuser isn't heating up. If the machine shuts down right after startup, the thermal sensor is likely engaging safety protocols.

Step-by-Step Solution

  1. Power off and let the unit cool down.
  2. Inspect the fuser for any jammed or wrapped paper.
  3. Check the fuser power cable connection.
  4. Examine the fuser thermistor for dirt or wear.
  5. Power on and wait for the warm-up cycle to complete.

Prevention and Maintenance

Avoid shutting down the copier abruptly during operation, as the fuser needs a gradual cooling phase. Replace rollers according to the manufacturer's life cycle.

When to Call a Technician

If the error persists, the fuser lamp or thermistor has likely failed and requires replacement to prevent safety hazards.
