@PaulHazelden (tenuki57):
I don't see "invalid argument" anywhere in the log. It looks to me that
SANE did not find any scanners. Was your scanner plugged in?
What does the following return:
scanimage -L
?

I then tried the next suggestion:
scanimage -x 210 --mode=Color --resolution=300 --batch
and this succeeded. If I attach the '--log=' option to this command
line, will that generate any useful information?

I have the same problem.
gscan2pdf: sane_start: Invalid argument
I would agree that scanner support is the responsibility of the
manufacturer, except that my system ran perfectly until I upgraded from
18.04 to 20.04.1. So whatever the manufacturer supplied used to work,
but the upgrade broke

Hans, we can certainly disagree. But it seems you as well as some of
the upstream devs do not understand much about packaging. If you want
timely fixes, pay someone to do it. If you want to make a mess of your
system, install random packages. I'm fine with any of that. I'm not
fine if then
Rolf, I would agree with you if bugs would be fixed in a timely manner,
but that is not the case. In the meantime, people go months if not
years with a scanner that does not work. That is unacceptable by any
standard. People should see my previous comment as a work around to get
things done.
Dave, are you still experiencing this problem?

"Invalid argument" when trying to scan

Please do not suggest to install third-party packages, even if from the

I had a similar problem with the default version of gscan2pdf available from
the default Ubuntu 16.04 repositories. I would scan, but the error message
would arrive after the scan was completed.

As you have noted, the 001:005 refers to the usb device. However this
can change between boots. Did you reboot between the gscan2pdf/scanimage
and epson sessions?
As you can reproduce this from the commandline with scanimage, I am
transferring this bug to sane-backends, as the bug must be in the

I get the exact same error from gscan2PDF with my HP 7510 all-in-one
scanner. (see attached Video). On two different computers. (note using
the HP scan utility works)
For the earlier Epson. The Epson ScanImage for Linux also works
normally.
Is there a better explanation what Invalid Argument is
The fact that you can reproduce this with the scanimage frontend tells
me that this is a problem with Epson SANE backend, and not with
gscan2pdf. If you look at the bottom the last log you posted, you will
see that this is the command gscan2pdf used:

I have a similar problem with a different scanner. The Epson GT-S80.
When I choose Doublesided scanning also Invalid Argument.
