  • 2Exhausted fuser heating lamp.
  • 3Unstable input voltage.
  • 4Control PCB power management failure.

Solutions

Quick Diagnosis

The error occurs immediately upon startup. If you do not feel heat emanating from the rear of the printer after several minutes, the fuser is likely failing to heat up.

Step-by-Step Solution

  1. Power Cycle: Turn off the device and unplug for 10 minutes.
  2. Direct Outlet: Plug the printer directly into a wall outlet, bypassing any surge protectors or UPS units.
  3. Temperature Verification: Turn the machine back on and monitor the display.
  4. Service Reset: Some service codes require access to the maintenance mode, typically performed by a trained technician.

Prevention and Maintenance

Use high-quality surge protection to stabilize input power. Perform preventive maintenance every 50,000 pages to inspect rollers and heating elements.

When to Call a Technician

If the error persists despite using a stable power source, the fuser lamp or thermistor has failed and must be replaced physically.
