Solutions

Quick Diagnostics

This error occurs when the fuser gets too hot, too quickly. Unlike the 5501 heat deficiency, this is an overheating safety lock. It often follows very heavy, continuous print jobs in small or unventilated areas.

Step-by-step Solution

  1. Power off the printer immediately.
  2. Disconnect the power cord to prevent residual heating.
  3. Keep the unit in a cool, ventilated area for at least 30 minutes.
  4. Power on. If the error remains, the fuser thermal sensor may be permanently damaged.

Maintenance and Prevention

Avoid placing the printer in cabinets. Regularly clear dust from the ventilation ports to allow fans to cool the device properly. Genuine Konica Minolta toner ensures your fuser performs as intended during long print cycles.

When to call a technician

If the 5502 error doesn't clear after a long cooling period, the thermal control logic or sensor is likely faulty and requires expert repair.
