how to resolve error code C3452
Error code C3452 indicates a Fusing Warm-Up Failure (Sub). It occurs when the Fusing Roller Sub Thermistor does not detect the required temperature within 30 seconds after a warm-up cycle begins, or the temperature does not reach the required level within the set time.
To resolve error code C3452:
1. Turn off the main power switch and allow the unit to cool down.
2. Check the Fusing Unit, especially the Sub Thermistor for damage or disconnection.
3. Inspect wiring and connectors between the thermistor and control board.
4. Replace the Sub Thermistor if faulty.
5. After repairs, reset the error code.
Ensure the fuser assembly is functioning normally before restarting the machine.
