Finally MS fixed the problem! The scan problem was solved by MS latest updates [2025-04 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5055523)]. Kofax PaperPort 4.7 SE (twain driver) works by re-installation of Brother driver and software after updates. Brother iPrint & Scan also works.
Am I to understand that now, after the last update on April 8, the scanner is also functional for scanning from device to laptop? Is the installation of the Brother application done normally, as before, or is another "trick" needed? Do I just have to uninstall all the Brother software and then reinstall it? Do you need to do something extra? My device is MFC-L8690CDW.
I don't like the Brother iPrint app. I prefer CC4.
If scanner is still not working after installing the [2025-04 Cumulative Update for Windows 11 Version 24H2 for x64-based Systems (KB5055523)], you will need to uninstall, ensure you reboot and then reinstall your printer/scanner software.
