I got a 220 myself and had to get the latest straight from the project's PPA. Are you using the SANE Project's PPA? If not:
sudo add-apt-repository ppa:sane-project/sane-release sudo apt-get update sudo apt-get upgrade That should pull the latest sane packages (Ubuntu/Debian lags hard). Try it again after getting the latest releases. On Sun, Jan 3, 2021 at 10:08 AM Volker Wysk <[email protected]> wrote: > > Hi > > I've got a new flatbed scanner, a Canon CanoScan Lide 300.
