SOURCE: Kyocera Mita 1500 Error code 6000

This C6000 error code is triggered by a few things all having to do with the fixing heater wire. Ask your technician to check the thermistor, the thermal cutout and the connection between the thermistor and the power supply board. My guess would be that the power surge overloaded the power supply board. This is not something that can be reset and may require new parts.
The manuals that describe the error codes are only available to Kyocera technicians, sorry.
