if you installed new developer unit you have to initialize it or else there wont be any or enough toner in the developer so its going to always add toner or print light or blank copies

Brocken internal thermistor wire.
Poor contact in the connector terminals
Defective laser scanner unit.
Defective engine PWB

my dear you chek heater unet problem

I think the Kyocera copier service manual you are looking for is available for download at http://www.copytechnet.com

C-6 abnormal temparature

your fuser tripped an error flag. Try power cycling the machine. If that does not work then press the button to check job status and enter 10871087. You might be able to enter that code from the copy screen. In any case lets continue, you enter that code and then screen changes. You then enter 906... That is a general reset. You could also try 163 that is a fuser reset. If neither one works then you need a new fuser unit

in many cases, the cause of fuser failure is not using oem toner.
