I can't reproduce any of these xases. However, I'm using a Mustek
scanner. 

Can you put these two pnm files somewhere on a web or FTP server or
send them to me personally (not the list!) if they are smaller than 4
MB. Maybe it's possible to see, if there is a problem.

Maybe a problem with the epson backend? In principle, the pnm output
of scanimage is ok.

I don't know if this helps, but scanimage can also produce tiff
images. If you can use GUI programs: XSane can produce jpeg files
directly.

I don't know if it's good:  convert (from ImageMagick).
