had a circuit board replaced recently??? if so check each and ever connection, pull each connection and reseat each connection one at a time while each connector is removed check all pins for a bent pin. Or replace the Print control board, Interface control board, image control board, and the overall control board, $$$$$$$$$$$$$$$$$$$$$$$$$ more then what you paid for the machine!!!! Then you will still have to remove each connection and reseat them and look for bent pins!!!!!

Hi, i have a konica minolta c6500, and i have a problem with error code c-6500. What happen?

Something with your developer causing not enough toner. Maybe an auger issue in the developer or in the toner feed itself?
