My 3100cn color laser has stopped working at all, and displays the error code 016-302. Does anyone know what that means and what to do about it. I've tried restarting many times, but no success. I can't find a list of error codes on line. Thanks.
That one is a pretty generic data error. The first thing I would try is removing all the data cables to see if you can get the printer to boot to ready. If that works then you can work to systematically rule out the cable, switch, driver, application and port you are printing through. In worst case scenario the network card/USB interface or the board they are housed on has gone bad.
