I tried a few different frontends including Image Scan and they all
produced the same horizontal lines.  Increasing the scan resolution
from 300dpi to 600dpi prevents the lines from appearing, but Image
Scan is the only frontend I've found that makes 600dpi available.
xsane and xscanimage both make 600dpi available on the Y axis, but the
available X axis resolutions jump from 300dpi to 1200dpi.  The problem
with Image Scan is it doesn't seem to have proper correlation between
the preview UI selector borders and the resulting scanned image.  It
also doesn't seem to allow the disabling of image processing.

Is there any way to try the epson2 backend's Artisan 700 support with
my Artisan 710?  epson2 doesn't support the 710 yet.  Maybe there's a
way to alter the scanner's USB device ID as it's presented to SANE?
