can you test whether it works with gnome's document scanner?

Comment 2 Alexander Stippich 2022-03-27 16:19:20 UTC

Please check with other software (e.g. gnome's document scanner) whether this works to locate the issue

Same problem with Gnome document scanner.

Comment 5 Alexander Stippich 2022-04-11 17:52:21 UTC

Then it is likely an issue with SANE itself. Could you please report the issue to https://gitlab.com/sane-project/backends/-/issues
Thanks!
