Canoscan LIDE 20 scanning in pink

Problem is: it's scanning and there is a lot of red in everything it scans. Used xsane (had to as root for it to see scanner) I looked at the bulb as it scanned and it was infact quite pink! Using xsane 0.91

My kernel is 2.6.5 and I am fairly sure I have the right sttuff loading

In my kernel I have all of them built in, would there be any reason to make them modules?

What can I do to have it scan not in pink? It scans in pink in that in xscanimage as well.

I bought one of these today! The first prescan I did was pink/reddish, but I noticed that the various balance controls were all over the place. I set them all flat, this time the scan was very good indeed (if a little noisy).

Have you tried playing with the Brightness, Contrast and Gamma settings?

Hey Zoko,

Could you do me a favour and tell me how you managed to get your scanner to scan *anything* in the first place? I am a total newbie and have absolutely no idea on how to get the thing working...please help!

This scanner is supported by "sane" so you just need to run xsane and it should be available to scan from.

At least that's how it works in PCLinuxOS!
