Mein Scanner funktionierte unter Ubuntu 16 und dann unter 18.10, aber jetzt funktioniert er unter Ubuntu 22 nicht mehr. Drucken ist aber ok. Mein Scanner ist RICOH MP 2014, hier ist die Ausgabe einiger Befehle:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Es gibt ein Problem mit den Berechtigungen für den Zugriff auf den Scanner über USB:
USB-Gerät 0x1d6b/0x0001 konnte um 003:001 nicht geöffnet werden: Zugriff verweigert (unzureichende Berechtigungen)
Sehendieser LinkDarin wird das Erstellen einer udevRegel für Ihren Benutzer erläutert, wenn der Scanner angeschlossen ist.
