Scans become blue

When i scan some photo's, after e few good one's, suddenly the photoscan's become blue, can someone tell me more about this??

Jan, post more information about the kind of scanner you're using, the scanning software, and the computer platform and operating system. I'm not sure it'll make a difference, but that kind of stuff is often very helpful in troubleshooting problems.

Thanks for the advise.
