If you happen to have a printer capable of the newer tech which eg Brother printers have then you don't actually need anything installed from the printer manufacturer. You can scan directly in any scanner software than can locate the printer that way.
As an example on Linux without Brother software installed, I could use the built in Linux scanner software, and it automatically finds the scanner on the network and can scan from it since the scanner includes the ability.
I don't think though that I've tried scanning on Windows 11 at all in the past year though lol. However, I have not installed anything from Brother on this copy of Windows 11 and going to Microsoft Store, installing Windows scan, and doing a test scan works just fine without a single configuration or anything else. I have not installed the printer/scanner on this computer via any means and only have made sure in Windows settings printers that its been found and assigned.
That should work too if you use the page feeder to grab multiple pages. If you have no page feeder then you're software bound anyway and there's a ton of ways to combine pdf pages into one doc anyway - that's not a scanner problem lol.
Any other issues, I'd suggest because the printer stinks or its too old and stinks that way.

*Note. I use printer and scanner freely since I use an mfc. I'm not concerned about specifics about the words. Just think scanner if you dislike the word printer lol.
