My Kyocera KM 2035 is showing error code A0 401

This goes away if ADF connection is removed. By the way ADF is not working also.
Anybody please help me I will be eternally thankful.

"If a C410 Error occurs, replace the DP-410 Main PCB Assembly, Ground Wire and Screw."
The PCBs part number is 303HL01018.
General Tech Bulletin 70 has all of the pretty pictures on what ground connections to test.
