PIXMA MX432 ADF not working or detecting documents

[yodakya]

The bed scanner works fine but the top scanner won't detect any paper or seems not to be detected by other scanning programs. Just nothing seems to trigger it at all. 

I'm using Windows 11. So maybe that's it.

Ran myself crazy trying to fix this on my MB2120, finally found that the paper type/size had to be correctly set in TWO different places on a Windows 10

Where is the other place? I've tried the setting in the scanner program. Where else does windows have a paper size setting?

One was in the printer settings on the computer, the other was on the printer display itself.  I spent two hours troubleshooting this glitch and never saw any mention of it.
