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.

SOURCE: kyocera mita j11 error code

On most Kyocera Mita copiers a J-11 code indicates a possible paper jam when paper is being fed from drawer #1, but sometimes a J-11 will be indicated when the paper fails to feed from the drawer. Check the paper stops and paper guides in the drawer and make sure that they are flush against the paper, also cleaning the paper feed and pick-up rollers with a rag dampened with just plain water will help sometimes unless the rollers are completely worn out. If all this doesn't help you may have a paper feed clutch or lift motor that has failed.
