[sane-devel] False colors with Canon LIDE 25

[Todd Pytel]

Hello,

I just received a Canon LIDE 25 and am hitting some problems with false
colors. I've basically never used a scanner before, much less on Linux
(though I'm pretty handy with Linux in general), so I'm not sure what
component of the scanning system I should be looking at. 

I set up the scanner without any issues - it's using libusb and
scanimage detects the make and model correctly, as well as identifying
the plustek backend. I've got xsane running fine as a regular user and
can preview and scan to an image. Full-color documents (like a map, for
example) seem to scan OK. The problem document is primarily
black-and-white text and line graphics (boxes and such), with a few red
numbers and graphics that I'd like to keep in color. When I scan this, I
get a lot of false color in parts that should be black - for example, a
solid black line that's part of a box will show up with a kind of
spectrum effect. I tried fiddling with a couple of the xsane settings,
but didn't come across anything helpful.

Again, since I don't have much scanning experience, I'm not sure if this
a problem with the hardware configuration or if it's just that I don't
know how to use xsane correctly. Probably the latter. Any advice is
greatly appreciated.
