Solutions

Diagnóstico rápido

If the error code C-3102 is displayed, the internal heat monitoring system has tripped. Check the unit for any visible burning smells or abnormal internal heat radiation.

Solución paso a paso

  1. Power down and allow the fusing unit to cool down completely.
  2. Open the fuser assembly and visually check for paper jams or stuck labels that may disrupt heat distribution.
  3. Close the fuser door firmly, ensuring all contact points are locked.
  4. Restart the system and monitor for success. If the code reappears immediately, the thermistor likely needs replacement.
