Lady with Barking Dog

My scanner has been doing this thing where the picture comes out lighter on one side. This isn't an issue with black ink drawings on white paper, but when there is color it becomes an issue. This has been an issue for a while, but it's been a while since I've scanned anything, and I forgot that it was an issue. Blerrrrgggh, I certainly don't plan on buying a new scanner any time soon, so I'm JUST GOING TO DEAL WITH IT.
