For many of you scan to smb on MAC OS X 10.7 is still an issue. For those there is a way to get the old scan to smb to work on MAC OS X 10.7.
You are going to have to try the following links below
The first link explains how to hack terminal in MAC OS X 10.7 to install the old smb protocol. The second link shows you have to install the old smb visually through a video and the last shows you how to install SMBUP. SMBUP is a utility that enables scanning in the older smb format.
If none of these work then you will have to use scan to email or scan to ftp. Scan to ftp also has to be enabled from terminal.
And don’t forget… depending on which version of MAC OS X you use… your OS X smb syntax might be different
