I'll try wine or run a vm. I will then try to locate a windows machine 
if those two options don't pan out.

The last time I tried to use it, it worked. That was Sept 2016.

scanimage -V
scanimage (sane-backends) 1.1.1-debian; backend version 1.1.1

I am not fluent in C++, but I am willing to help in any way.

There is a more recent version 1.2.1.
Here are the changes

|genesys:|

  * Fixes for unit test build errors related to GCC 12.
  * Fix for 32-bit limitation on scan line size which caused early
    abort. of scan.
  * Build issue fix for OSX.
  * Button support for Canon 8400f scanner corrected.
  * Support added back in for Plustek OpticFilm 7600i: config file entry
    was missing.

The second one is the only one that  seems like it may be relevant. I 
don't know.

I attached lots of my local output and versions to the original email. 
Did those make it to the list?
