@Ken Wright I did set up the links with "sudo cp /usr/lib64/sane/libsane- brother4.so* /usr/lib/x86_64-linux-gnu/sane"
The "sudo sane-find-scanner" does not find it - that seems to be looking for USB scanners but this is network attached. It found my TV tuner (PCTV 801e) and thinks it may be a scanner. "sudo scanimage -L" also does not find it See below peter@andromeda:~$ ls -l /usr/lib/x86_64-linux-gnu/sane/*bro* -rwxr-xr-x 1 root root 158336 May 16 19:04 /usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so -rwxr-xr-x 1 root root 158336 May 16 19:04 /usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so.1 -rwxr-xr-x 1 root root 158336 May 16 19:04 /usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so.1.0.7 peter@andromeda:~$ ls -l /usr/lib/sane/*bro* lrwxrwxrwx 1 root root 35 May 16 18:45 /usr/lib/sane/libsane-brother4.so -> /usr/lib64/sane/libsane-brother4.so lrwxrwxrwx 1 root root 37 May 16 18:45 /usr/lib/sane/libsane-brother4.so.1 -> /usr/lib64/sane/libsane-brother4.so.1 lrwxrwxrwx 1 root root 41 May 16 18:45 /usr/lib/sane/libsane-brother4.so.1.0.7 -> /usr/lib64/sane/libsane-brother4.so.1.0.7 peter@andromeda:~$ sudo sane-find-scanner # sane-find-scanner will now attempt to detect your scanner.

But the scanner is no more recognized. Scanners that are affected are(besides others): - Epson Perfection V10 - Epson Perfection V1000 - Epson WorkForce GT-1500 - Brother MFC-8510DN - Epson Perfection V33 It is to note that the probability that the scanner manufacturers fix things others broke is below 100%.
