  • 1Heater burnout.
  • 2Thermistor sensor failure.
  • 3Roller toner buildup.

Solutions

Quick Diagnosis

If the machine shows E002 immediately upon startup, the thermistor or heating element has failed. A power cycle is necessary to determine if it's transient or permanent.

Step-by-Step Solution

  1. Cool down period: Power off the printer for at least 10 minutes to allow the fuser heating element to cool safely.
  2. Physical inspection: Open the rear access door to check for any paper fragments blocking the fuser area.
  3. System restart: Restart the device in a well-ventilated room. If E002 reappears, the fuser unit is faulty.

Prevention and Maintenance

Avoid placing the machine in enclosed areas with poor ventilation. Use only original Canon cartridges to minimize toner buildup on the fuser surface.

When to call a technician

If the E002 persists after a power-down, the unit must be replaced by a qualified technician.

Frequently asked questions

The printer is unable to maintain the required temperature in the fuser assembly, causing an E002 thermal fault code.

Overheating can damage the printer internals. Turn off the printer immediately to prevent damage.

The fuser is a core maintenance part, not a daily consumable like the toner cartridge.

Ensure your printer is placed away from heat sources and maintain a good airflow around the device.
