Windows did not recognize the scanner at all. When "installing a new scanner", MS recognized the MS scanner and the already installed Canon scanner. The Brother brand or DW40 type did not appear anywhere and could not be retrieved. Brother IT specialists also did not know what to do with the situation and referred to Japan or the USA.
After trying the IT administrators' solution several times, I turned everything off and reinstalled it one more time and sure enough, the scanner was recognized and everything is now operational. There has been no update or otherwise. Apparently it's a bug that clears itself after repeated uninstalling and reinstalling. But I think this has happened 20 times or more to great frustration.
