XSane is able to scan 16 bits per pixel in gray mode. You can check such things with the test backend to be sure that it's not a problem of the backend: "xsane test". However, I don't know if your backend is able to provide 16 bits per pixel in gray mode. > Where does xsane get this information, >From the backend. > and how can I change it? If the backend supports 16 bit, it will usually provide an option like "Bit depth" to select the depth. Bye, Henning
