Brother Printer issues with Sequoia 15.1 update

I have scanned from my Brother MFC-L3770CDW printer menu to my Mini Mac and it has worked great up until I updated my OS. Once updated, I can no longer Scan from my printer menu (quickest scan method for me), I have to use Brothers iPrint&Scan app. I can still print from my computer.

I have deleted the printer and reinstalled it

I have updated the firmware on the Printer

I have reset the printer

Before I reset the printer, it was showing a communication error of some sort, After I reset the printer, the scanning function will not find my Mini.

Mac mini, macOS 15.1

If you're able to print but not scan with your Brother MFC-L3770CDW after updating to macOS Sequoia 15.3.1. - This issue has been reported by other users as well. After trying many things over a few weeks, this (in one second) resolve this problem (Thanks to my buddy ChatGPT):

You might also need to update your printer drivers first which may be why the network settings got turned off. The link is for my model, search for yours and if it does not fix the problem follow part 2 below...

Check Local Network Permissions:

Navigate to System Settings > Privacy & Security > Local Network.
Ensure that applications like Brother iPrint&Scan have permission to access the local network. If they're disabled, enable them.

Thank you, Al Weir! I guess upgrading to Sequoia 15.1.1 clobbered that setting. Works fine, now!
