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. --Todd
