Honestly -- I do not buy that it is solely a "MS issue" as Brother says.....
Yes I know there are other makes/models out there having the same issues.
But explain why other software - like the NAPS2 app....works perfectly fine with the scanner function.
"Something smells in the state of Denmark" ...lol
I am having the SAME issue on my very old W10 machine....all this started after I shut down the Brother multifunction machien as well as the PC for a week.
The W11 machine is brand spanking new, a move I made BECAUSE I thought the 10 year old+ W10 PC was the culprit....
And for it to magically be working again on my W11 PC scares me...lol
