Hi,
I'm no Epson expert but maybe some general comments:

That's the standard error message if no other error message is suited
better. It basically means: "I can't handle one of the
options/arguments you gave". If it happens when pressing the scan
button, it usually means you either selected a combination of options
that doesn't work or something is wrong with the geometry options.

You are trying to scan an image with width == 0 (tlx==brx). Check the
sliders for the geometry in XSane. Maybe you swapped the top left and
bottom right edge of the image in the preview window?
