I have the same Kodak i1220 scanner and have been able to get it to work on Windows 11.
The latest driver here (https://www.kodakdriver.com/kodak-i1220-scanner-driver/ ) was version 4.09
You also need Smart Touch software version 1.5 works (I think you may be able to get it here, but I had it stored from previously https://kodak-i1200-smart-touch.software.informer.com/versions/ ) I have tried version 1.7.122 which is the latest but I couldn't get it to work on Win 10 or Win11. The older version means the button on the scanner itself doesn't work, but this is a minor inconvenience (You may be able to do it with a Button Remapping Tool in C:\Program Files (x86)\Kodak\Document Imaging\kds_i1200\Smart Touch or messing with the registry, but I haven't tried that yet)
Once you're all set up, the user manual can be found on your computer here, C:\Program Files (x86)\Kodak\Document Imaging\kds_i1200\Smart Touch\Workstation\Help
If you need to copy settings over from a previous computer, they are stored in two places. The most useful being your setting shortcuts for the scanner itself C:\ProgramData\kds_kodak\kds_i1200\profiles. NB (program data is only visible if you set 'show hidden files')
The other is the quick start buttons 1-9 (part of the Smart Touch software) C:\Users#####\Documents\Smart Touch\i1200\Settings
