Konica minolta Bizhub Pro C6501 Error C 6708 ( Urgent )

Hi ,

I have a Bizhub Pro C6501, which displays the error code C6708 in starting up, I tested with Printer Control Board, OACB, CCD, SCBD, and check Scanner Home Position Sensor, the connectors between this share;

PS: When the scanner section reaches home position sensor remains fixed in the same position after the machine displays the code.
