Scanning and Printing WotC Tiles

[Prosopis]

So I recently had the idea to scan in my WotC dungeon tiles and print out custom maps. The problem is that the tiles scan terribly. It's as if the tiles are reflecting bits of the light from the scanner and populating much of the image with little white pixels. I have a nice scanner (Cannon 5600F). Has anyone tried to do this and had success? Am I an idiot (on second thought, don't answer that)?

The tiles are designed to be difficult to pirate.

I think this program will do the same thing and save you the time of scanning.
