Common causes

  • 1Defective thermistor.
  • 2Debris obstructing the fuser unit.
  • 3Power supply fluctuations to the heater.
  • 4Contaminated temperature sensors.

Solutions

Quick Diagnosis

This error implies the system reached an out-of-range temperature. Check if the error appears immediately after the warm-up cycle. Any physical debris around the heating rollers might be causing erratic temperature readings.

Step-by-step Solution

  1. Disconnect the printer and let it rest for 20 minutes.
  2. Inspect the fuser unit for paper jams or obstructions.
  3. Ensure the unit is correctly seated in its cavity.
  4. Reboot the machine.

Prevention and Maintenance

High-production environments require regular fuser cleaning to remove toner buildup. Consistent maintenance ensures that the termistor sensors remain accurate.

When to Call a Technician

If the error reappears immediately upon power-on, the thermistor or heating element has failed and requires official Ricoh part replacement.
