C6400/6000 on Kyocera Mita KM1500

Almost all kyocera Mita products display error message C6XXX whenever a problem is detected in fixing temperature or fixing unit. C6000/C6200/C6050 and C6400 all are related to fixing unit. Service manual states that possible causes are as below:
C6000 & C6050
  • Poor contact in the thermistor connector terminal.
  • Thermistor installed incorrectly.
  • Thermal cutout triggered.
  • Heater lamp installed incorrectly.
  • Broken heater wire.
C6020

  • Broken heater control circuit on the power supply board.
C6400
  • Poor contact in the connector terminals. Check the connection of connectors CY7 on the engine board and CN2 on the power supply board.
  • Defective power supply board.
  • Defective engine board.
Sometimes only an unstable power source is the cause of these error messages.

    Hi your blog is very interesting. I have one problem i am facing in ir2318L. When the machine is switched on t diaplays the following error: Front/left door open please close the doors(sic). I checked both the switches in the front door and side door. the switches r okay and the doors r closed properly even then the same error persists. I also tried shorting the points of the switches in case the switch has gone bad but the error is not getting resolved. I am doubting the power supply pcb . please help me know of any other solution.
