In the file /etc/sane.d/dll.conf
try commenting out the Samsung driver: smfp
which Samsung's Unified Linux Driver appends to this file.

I had this same problem. "scanimage -L"  worked but "xsane" no longer did,
because xsane loads the drivers in /etc/sane.d/dll.conf and 
Samsung does not provide smtp, although it does create device nodes
for its multi function printer.
