I'm having the same problem with Samsung M2070 scanner, but thanks to the information here I was able to patch it working. I linked the files located in /usr/lib/sane (copied there likely by the samsung driver installer) to /usr/lib/x86_64-linux-gnu/sane and now the scan works both over the usb and the network.
