The epson backend maintainer may understand that better, but my
impression is that xscanimage sets the resolution to 301 but it
shouldn't. In fact I'm surprised that xscanimage provides a slider at
all. The epson backend code shows that the backend provides a "word
list" so, xscanimage shouldn't show a slider but a selection menu.

Does xsane show a slider or a selection menu with fixed values for the
resolution?

Are you sure you are using the epson backend from SANE 1.0.9 and not
the Epson software (KOWA)?

Also make sure that there is no old *.rc file in ~/.sane/xscanimage/ .
I don't know if old files can make trouble here but you never know.

Bye,
