Step-by-step Solution

  1. Extended Shutdown: Keep the machine powered off for 30 minutes to allow residual heat dissipation.
  2. Reboot: Turn the machine on; if the error returns instantly, the heating mechanism is failing.
  3. Fuser Inspection: Check for any paper scraps inside the fuser unit that might trigger a sensor fault.

Prevention and Maintenance

Never perform a hard power-off while the fuser is at operating temperature. Keep rear cooling vents clear. Use only OEM certified consumables.
