My Brother MFC-J220 works now with the 1.0.27-1~experimental2ubuntu2.1 packages.
The brscan3 driver installs files in /usr/lib64 and /usr/lib64/sane.
I linked them by
'sudo ln -sfr /usr/lib64/libbrscandec* /usr/lib/x86_64-linux-gnu'
and
'sudo ln -sfr /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane'
