mfc-7440n scanner ubuntu16.04 fix
Ever since upgrading my ubuntu on my main computer to 16.04 the scanner hasnt worked, i used the brother install tool and added the scanner using this command
sudo brsaneconfig3 -a name=MFC-7440N model=MFC-7440N ip=192.168.0.67
but still nothing. a bit of poking around i found this and im back in business!!
sudo mkdir /usr/lib/sane
sudo cp * /usr/lib64/sane/* /usr/lib/sane/
and
sudo cp /usr/lib64/libbrscandec3.so.1.0.0 /usr/lib
sudo cp /usr/lib64/sane/libsane-brother3.so.1.0.7 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so.1 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/libbrscandec3.so /usr/lib
sudo cp /usr/lib64/libbrscandec3.so.1 /usr/lib
and its fixed!! thanks to klaus15 on ubuntu forums!!
