Using 18.04 (wip), I had the same problem with a Brother J4625DW all in one printer/scanner. Installing the driver from Brother (http://support.brother.com/g/s/id/linux/en/instruction_scn1b.html?c=us_ot&lang=en&redirect=on) instead of the brother driver from the repos solved the problem, so it might be a workaround for those using Brother scanners.
