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 referring to in the error handling?

I'll make a log of the HP output later today.
