I tend to think of my scanner bed the same as a sheet of paper, so that the narrow parts are the top and bottom and the wide parts are the sides. If I scan in 2 page mode, I notice that sometimes the scanner likes it with the book's right page at the top but sometimes if it is getting persnickety I reverse that. If I scan in one page mode then it doesn't matter because it has to go whichever way the book fits on the scanner. Jamie in Michigan Currently Reading - Chocolate Chip Cookie Murder by Joanna Fluke
