Kyocera ECOSYS P3155dn error C3300: Fan Failure

The Kyocera ECOSYS P3155dn error C3300 is a system warning indicating a mechanical failure in the cooling fan. This code appears when the sensor detects the fan is not spinning at the required speed or is physically blocked. Immediate action must be taken to verify the airflow to prevent heat damage.

Common causes

  • 1Excessive dust accumulation blocking the fan blades.
  • 2Speed sensor failure due to motor bearing wear.
  • 3External obstruction by objects placed near ventilation vents.
  • 4Short circuit in the wiring powering the main fan.

Solutions

Quick Diagnosis

The C3300 code often appears after an unusual sound is heard before the panel locks. Checking if the rear fan feels stiff to the touch with the power off is key to confirming a cooling motor failure.

Step-by-Step Solution

  1. Visual Inspection: Turn off the device and check that no foreign objects are blocking the rear ventilation grill.
  2. Dust Removal: Use compressed air to clean dust buildup from the main fan blades.
  3. Force Restart: Power on the device again after ensuring the fan is not physically blocked.

Prevention and Maintenance

Keep the printer at least 15 cm from walls to allow air circulation. Periodic cleaning with compressed air prevents lint from blocking internal vents.

When to Call a Technician

If the fan remains stationary after cleaning or the error recurs immediately, the cooling motor has reached the end of its life and requires replacement by a qualified technician.

Frequently asked questions

This code indicates the speed sensor detected an abnormal rotation of the cooling fan, which triggers safety mode.

No, for thermal safety, the system shuts down immediately to prevent major damage from overheating.

Not directly, but non-original toner may create excess dust particles that accelerate fan obstruction.

Use a vacuum or compressed air on the side vents every six months to ensure optimal airflow.
