It’s been a while so can’t offer (remember) specifics. Suggest you look at past comments and try the recommended revisions.
Right now (holding my breath) no problem with scanner operation or behavior. It comes up differently, depending on whether or not it was on when turning on the computer, not a problem.
Good luck
I have a Brother MFC 9325 CW that won't scan. I had to get a third party app to use the scanner. It worked fine under Windows 10. I've gone through the entire process provided by brother. I had to bring in an expert to show me how to use another app on my desktop. I find it disturbing that Microsoft provides no solution.
