canon says no support at all for this model anymore so fedora must've had a good old package. find that package. maybe it came bundled in a scanner package and find that package?
I'm of 2 minds: you really have to find a scanner driver, so install sane-backends to be sure.
That might guarantee another program can access it. Grscan2pdf has always detected my scanner even though its clunky. stuff like simplescan and skalnlite have never worked for me. Gscan, yes and an wild animal called Xsane also detected it. ***Disclaimer/edit--I don't use none of those anymore since flatpak has a program just for my Epson model now----flatpak search canon came out negative butflatpak search scanner came up with a truckload.
I wonder what the internets say about a N670U package floating around, as in source code (not deb or rpm)?
where there's a will there's a way here, you will win in the end. trial and error.
