Error C-4501 Konica Minolta bizhub PRO 1052: Diagnostic

The Konica Minolta bizhub PRO 1052 error C-4501 identifies a thermal anomaly detected in the fusing unit. This error occurs when the control system notices the fuser isn't reaching required temperatures or is exceeding safety limits. Why does my bizhub PRO 1052 show error C-4501? It is usually caused by a faulty thermistor or premature wear of the fusing rollers due to intensive use cycles.

Common causes

  • 1Fuser temperature sensor (thermistor) failure.
  • 2Overheating due to internal ventilation obstruction.
  • 3Natural wear of fusing unit thermal components.
  • 4Use of unsuitable paper requiring excessive fixation heat.

Solutions

Quick Diagnosis

The C-4501 error often appears after long print sessions. If the panel shows this code, do not try to restart it repeatedly as this can trigger even harsher safety sensors.

Step-by-Step Solution

  1. Switch off the device and unplug power immediately.
  2. Wait 30 minutes for the fuser to cool down naturally.
  3. Remove the fuser unit and visually check if the film has ripples or burn marks.
  4. If the unit looks intact, contact a technician to verify the thermistor and sensors.

Prevention and Maintenance

Replace the fusing unit according to the manufacturer's maintenance schedule. Ensure paper used is compatible with high speeds, as thick paper can force excessive fuser heat.

When to Call a Technician

C-4501 is a high-temperature fault. If it persists after cooling, a professional must inspect the fuser power circuit.
