The upstream version of iscan has not yet implemented 16bpc scanning. See lines 558-559,572 in backend/dip-obj.c in the source.

Reason for closing: Won't fix
Additional comments about closing: iscan was removed from the repositories for a lot of incompatibilities with glibc and for a weird releases schema (newer versions are specific only for some models)
