Hal LewisI just lay the slab down on the scanner and it comes out fine. I've never had your problem. Weird.
The scanner is at the office, so I don't know what brand it is.
I use "maximum" resoution when it gives me the choice on how to save the scan... but I really don't know if that makes a difference.
I don't have an answer for you... but I did want you to know that it can be done because I do it without any special equipment or anything.
