How do you know what to change your settings to when scanning a book? I have a book that has an incredible amount of junk in it, and I have no idea how to get rid of these errors. If you don't know what kind of page it is, dark or light, how do you know what to change settings to? I tried changing some of the settings but it is making no difference.
