You probably need to install the Brother drivers. There are two iirc, and need to be installed in the correct order and support programs. Available through the support tab on the Brother web-site. The config program has a very comprehensive list of settings which you put into a config file. Use scanimage -L to find the usb parameters and something like #export ads='brother4:bus2:dev1' then scanimage --device-name=$ads scanimage itself has a number of parameters.
A couple of years ago I was given a Brother ADS-1500 scanner to scan a large number of documents. Installed the drivers, and ended up scanning just over 2100 pages in one day. The ADS1500 is a small thing, powered from a power wart and uses USB, but very fast. At one point I did nearly 200 pages in one continuous call, feeding new pages into the back of the feed stack. I used: # double sided scanimage --device-name=$ads --resolution 300 --format=tif --source='Automatic Document Feeder(left aligned,Duplex)' -x 215 -y 280 --batch=$2%d.tif --batch-start=$3 --batch-count=$4 --batch-increment=$5
which numbers the output images by 1, 2 or -2 if working from the back of a book. The x and y parameters are the page size and you can limit the scan viewport to ignore parts of the physical page.
