Could you give us some details as to what occurs when you try to use it? I usually find that there is a dependency issue whenever I have had issues in the past like this. Perhaps start by showing us the output of: scanimage -V and scanimage -L > I contacted Brother and they concluded that Ubuntu had changed something > and neither Ubuntu forums or Brother could work it out.

If not, there is a work-in-progress SANE backend for Brother devices, and some people have found that it works OK for them. Details here: https://gitlab.com/sane-project/backends/-/merge_requests/751 . If all else fails, we can get you hooked up with a copy of this configured for your device. Cheers, Ralph
