Greetings,
I just received an Epson XP-4100 multifunction printer, and connected
it to an Ubuntu 20.04 desktop, with all updates installed, as well as
the packages sane and sane-utils
Printing works fine, scanning does not. lsusb, scanimage and avahi
browse do list the scanner (see outputs below), and its web interface
of the scanner is reachable at http://127.0.0.1:60000/
However:
* the Epson imagescan package does not find any device.
* the web interface at Product Status -> Network says
Device Name :
EPSON309A2B
Connection Status :
Disable
and I can't find any way to enable it from there
* if I run scanimage I get "scanimage: sane_start: Invalid argument"
(see details below)
* skanlite sees the scanner, but cannot actually scan: it just makes
it click for a few minutes, during which the scanner display says
"Scanning the original", then aborts, just like scanimage (see its
output below)
I have configured and used lots of scanners under Linux for years
including shell scripts to scan lots of documents, but honestly I have
no idea what to do how or check next to make scanning work this
time... Any advice is very welcome
Thanks in advance,
Marco

Hi
Update your sane version, this should solve the problem:
# sudo add-apt-repository ppa:sane-project/sane-git
# sudo apt-get update
# sudo apt install libsane libsane-common sane-utils
