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. Yay.

Title:
Brother's printer/scanner drivers awkward to find and install
Status in cups package in Ubuntu:
Opinion
Bug description:
Binary package hint: cupsys
Hello,
I have the multifonction laser printer and scan Brother DCP-7030.
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.
Thanks in advance for your help. Best regards,
Xavier
