Keep on getting a 077-120 and paper jamming in registration assembly

Where does it physically jam?
There are many sensors here and it just reports back the error code of the first jammed / set on sensor. it can be slipping on picking up paper and the timeing is thrown out, it can be the inverter gate, the fuser just about anything at the moment.
