Code C6050 is related to the fuser temperature and it is common on all Kyocera copiers. To reset you must enter the service parameters and clear the code. Enter 1087 1087 this gets you into service mode and 163 is the parameter that clears fuser faults while 903 will clear any other disabled functions. If the fault re-occurs then a fuser repair is required. The lamp is blown or the thermal fuse is blown or the thermistors need to be replaced
