Followed Brother MFC-L2700DW printer does not work to install the printer/scanner driver
During the install I can print a test page, via USB. Can't scan though.
Going to the printer – select Scan button / scan to PC / scan to file / Start times out at "connecting to PC" on the display
In Ubuntu 16.04, running simple scan / select scan times out with the error "failed to scan, unable to connect to scanner"
Retried both of the above after a Ubuntu restart. No joy.

I had a similar problem with brother printer/scanner MFC-J625DW.
Could not get the scanner to work until I followed the instructions on this faq. Second item, "I cannot find the brother machine". Apparently, some files may be copied into the wrong folder. My system is lubuntu 17.10 32-bit and the driver is brscan4.
According to the faq the fix is :
Check if the following directory exist.
For 64bit Users:
/usr/lib/x86_64-linux-gnu/sane
For 32bit Users:
/usr/lib/i386-linux-gnu/sane
Type the following command if the above directory exists.
For 64bit Users: Command :
sudo cp /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane
For 32bit Users: Command :
sudo cp /usr/lib/sane/libsane-brother* /usr/lib/i386-linux-gnu/sane
Next to this, your username must also be part of the group owning the scanning device. 'lp' in my case. And if you want to start scanning from the device, you need to install and run first

To clarify I will list all actions I did to get my MFC-J625DW to work (reboot between some steps may be useful):
sudo adduser <myusername> lp
lsusb
, note the busnr and devicenr of the brother, and executels -l /dev/bus/usb/busnr/devicenr
(3 digits per nr)sudo apt install gimp
sudo apt install sane sane-utils libsane-extras xsane
