If the page stalls just after pickup and the second side cleaning brush has rotated for the CIS to see the white reference section and the self adjustment fails, the machine is too stupid to know what to do in this instance and will not return the brush to the home position and will produce the 6105 error code.
I have had the MFP board cause this very issue.
For absolute confidence it's the MFP board, try another DF-701, it will do exactly the same thing if it is.
I had this on a 454e - replaced the black Displayport/CIS cable (A3CEN11711), sensor (PS7), motor (M5) and DF board that the service manual suggested. The problem went away for a couple weeks but eventually came back. Tried another DF-701, same problem.
Tech support had me clean the two white 50pin flat ribbon cables. One goes from the Dual Scan board to the MFP board, another from the PRCB to the MFP board. Pull them out, clean the contacts with rubbing alcohol and blow out the connectors on the board with compressed air if you wish. The machine has not come back for months now.

Tired everything suggested but no luck with that. Ended up going into the service mode and adjusting the home position sensor and that solved it...so far lol but thanks for the help.
