 Once the paper is liberated from the spine, it can be scanned one sheet at a time using a traditional flatbed scanner or automatic document feeder.Pages with a decorative riffled edging or curving in an arc due to a non-flat binding can be difficult to scan using an ADF, as they are designed to scan pages of uniform shape and size, and variably sized or shaped pages can lead to improper scanning.The riffled edges or curved edge can be guillotined off to render the outer edges flat and smooth before the binding is cut.
