The solutions I have found online say to add users to saned and scanner groups. I don't have a scanner group. I also found a solution that suggested I also tried to change permissions

I had a similar problem on CentOS a while back that was (temporarily)
solve by putting the user into the lp group, which owns the scanner.
I'd say run an 'ls -l' on your /dev/<scanner-id> file and see which
group owns it, then add that group to your user(s) who need to use the
scanner.

I'd strongly urge you not to use Canon printers or scanners with Linux
- as much as I like them, they are poorly supported and don't work
properly with most of the drivers, if you can even find them, and
that, unfortunately, includes (x)sane.
