Like to try, I do have the Windows driver but regret don't have the skills. I'll keep a note of this "just in case". Probably unsubscribe soon, SANE is an excellent project but I can't do anything with the advice I've been given, let alone contribute anything. So I'll sign off by thanking you and Theodore for trying to help. Regards-Philip
