Here's a procedure that worked for me in Ubuntu 18.04 Bionic. For this procedure the user is "bob"
1) Install the latest brscan2 package (I have brscan2-0.2.5-1.amd64.deb which I downloaded in 2014) 2) Manually link the drivers brscan2 installed into /usr/lib/x86_64 -linux-gnu/sane/ and /usr/lib/x86_64-linux-gnu/ bob:~$ cd /usr/lib/x86_64-linux-gnu/sane bob:/usr/lib/x86_64-linux-gnu/sane$ sudo ln -sf /usr/lib64/sane /libsane-brother2.so [sudo] password for bob: bob:/usr/lib/x86_64-linux-gnu/sane$ sudo ln -sf /usr/lib64/sane/libsane-brother2.so.1 bob:/usr/lib/x86_64-linux-gnu/sane$ sudo ln -sf /usr/lib64/sane/libsane-brother2.so.1.0.7 bob:/usr/lib/x86_64-linux-gnu/sane$ cd .. bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrcolm2.so bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrcolm2.so.1 bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrcolm2.so.1.0.1 bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrscandec2.so bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrscandec2.so.1 bob:/usr/lib/x86_64-linux-gnu$ sudo ln -sf /usr/lib64/libbrscandec2.so.1.0.0 3) At this point scanimage -L should detect the scanner when run as root. $ sudo scanimage -L 3a) If it doesn't work and especially if you're running something other than Ubuntu Bionic, you might make verify SANE is looking in the right directory using the debug flag $ SANE_DEBUG_DLL=128 scanimage -L 4) Create a udev file so the scanner is accessible to a scanner group $ sudo gedit /lib/udev/rules.d/96-brother-scanner.rules -- with the following contents: # Brother DCP-7020 scanner SUBSYSTEMS=="usb" \ , ATTRS{idVendor}=="04f9" \ , ATTRS{idProduct}=="0183" \ , ACTION=="add", \ , MODE="0664", \ , GROUP="scanner" \ , ENV{libsane_matched}="yes" # note this udev instruction ends lines with \ # backslash so the single comma-separated # udev command is not crammed onto one line. # END OF FILE 5) Add the user bob to the scanner group (as specified in the udev file above): $ sudo adduser bob scanner 6) If you're bob and you weren't already in the group you'll have to log out and back in, or reboot the system. To reload udev: $ sudo udevadm control --reload-rules --> Everything should work after you reboot / login / reload.

It works very well in Ubuntu, but with some hard configuration. Printer is automatically detected when connected in USB, but Ubuntu does not propose DCP-7030 drivers, only DCP-7025, and it doesn't work well. To get DCP-7030 fully recognized and well printing / scanning, I have to do this (it's a short summary) : http://solutions.brother.com/linux/en_us/before.html - Printer BROTHER DCP-7030 : cd ~/desktop sudo aa-complain cupsd sudo mkdir /usr/share/cups/model http://solutions.brother.com/linux/en_us/download_prn.html#DCP-7030 sudo dpkg -i --force-all --force-architecture brdcp7030lpr-2.0.2-1.i386.deb sudo dpkg -i --force-all --force-architecture cupswrapperDCP7030-2.0.2-1.i386.deb http://127.0.0.1:631/printers/DCP7030 : OK After that printer works - SCANNING : Install scan-key-tools / Brscan3 http://solutions.brother.com/linux/en_us/download_scn.html#brscan3 http://solutions.brother.com/linux/en_us/instruction_scn1a.html sudo gedit /lib/udev/rules.d/50-udev-default.rules : in section "libusb device nodes", replacer 0664 by 0666 sudo lsusb Bus 001 Device 004: ID 04f9:01a Brother Industries, Ltd Go to dev/bus/usb : bus 1 and device 4 is root owned Open it in Nautilus as root, change it to my user name and take ownership Now Simple Scan works, Brother-DCP is seen. But... big problem ! At each restart of Ubuntu or DCP Brother, permission resets and comes back to root, I have to change ownership and re-log each time, this is not nice... Is it a way to "protect" the file against erasing or permission change ? It's also true for other models than DCP-7030 (like DCP-7040...). I do not know if it is a Cups / Ubuntu "bug" or Openprinting missing for new drivers, but as Brother gives functional drivers for Linux, this should be easily implemented I hope, as more and more materials are natively identified in Ubuntu.
