I'm running Ubuntu 16.04 and a brother DCP-375CW, a printer and scanner all in one.
I downloaded the drivers and used the Driver Install Tool by brother.
This is the result: the system says the drivers are installed. The printer is actually working. But Simple Scan refuses to recognize a driver and xsane won't even recognize a scanner.
I tried some instructions I found on the Internet but most of them seem to be for older Ubuntu Versions.
I'm worried that there is something different with Ubuntu 16.04.
$ dpkg -l | grep -i Brother

I only had to do this single step (mentioned earlier but that answer also included other steps). I have a Brother DCP-L2500D and I run Ubuntu 16.04.
Open this file
Add the following line to the file, just before the line
# The following rule will disable USB autosuspend for the device
Restart (well that's two steps :-))
