Image Scan! is making up its own list of "supported" resolutions.
Only the maximum in the list has any correlation with the device's
list of supported resolutions.

I would expect 100, 3200 and 6400 in that list, at the very least.

What option would that be?  The epkowa backend doesn't do resolution
ranges for this model, only lists.  Or do you mean a full list?

Create debugging output with both iscan and xsane and compare.  You
can also send me the debugging output (via this list) for xsane so I
can take a look.  If you do, please also provide information on your
distribution and xsane and iscan versions used.

You probably just want to start the application(s) and maybe change
the document source (flatbed to ADF for example) or expose that
advanced option you mention.  You do not need to scan anything.

You can create debugging output by running the following command

  SANE_DEBUG_EPKOWA=127 xsane &> debug.log

Please compress the debug.log file before sending it.

Hope this helps,
