While I can't really tell you how to fix it, what causes the problem is actually trivial. Lets say that the scanning software is expecting the scanner to send 541 pixels per line and the scanner actually sends 542, each row gets offset by one leading to a very nice 45 degree slant to the right. If it sends 540 you get a slant to the left. It's a very simple off-by-one error. Maybe if you try scanning different sizes to see which ones work and which ones don't you can get some kind of idea of where the discrepancy lies.
