Can't Access Brother Printer Scanner

Hello Apple Support Community,

I updated to Big Sur yesterday. I tried to open my scanner in System Preferences > Printers & Scanners but got this error message:

You do not have permission to open the application “Brother Scanner”.

Contact your computer or network administrator for assistance.

And also: Failed to open a connection to the device (-21345)

I also downloaded the Image Capture application as recommended on the Brother website but got the same error messages.

My iMac is a standalone machine not on a network.

I'm on an mid-2014 iMac and Brother MFC-J880DW. I've had this printer for a few years and didn't have any issues when I updated to High Sierra.

Any advice?

Thank you!

iMac 21.5″, macOS 11.5

If you prefer to use the built-in drivers from macOS, then

Become root in the terminal using sudo
cd to /Library/Image\ Capture/Devices/
Change group on the Brother Scanner.app:

chgrp -R staff Brother\ Scanner.app

I am having the same problem with the latest Mac OS on a new MacBook Air from 2021 with my Brother printer/scanner. I would be curious to find out what they told you. Thank you!

BTW I can't remember of a logout or reboot was perhaps also part of my process here, could easily have been...

Winner, winner, chicken dinner! That is definitely the easiest solution. Thank you for sharing that. I can now scan again as normal.

Thank you for this! It took a few tries and recalling DOS and BASIC principles, but I got it within just a few minutes.

A restart is required after this to properly work.

I use Brother iPrint&Scan app for scanning on my Mac. It is available in the Mac App Store.
