[sane-devel] requesting help with setup of Kodak 5100 AiO scanner

I posted to the list because I was having trouble scanning a  
black-and-white document with my Kodak 5100 AiO, and on Wed, 03 Sep 2014

Hi Paul, and thank you for your reply.  If you're one of those wonderful  
people who make useful software available to everyone for free, then thank  
you especially for that!

I did as you asked, and scanned the same document in color using the  
default settings.  The results are somewhat psychedelic:

The black comes out fairly black, but white isn't white unless it's near  
something black.  No wonder I wasn't able to get a reasonable scan despite  
all my tweaking, if color settings were the problem but were unavailable  
to me in "gray" mode.
