What Is Scan Once Print Many?
In a digital copier the original is scanned into memory, and then reproduced from memory rather than being scanned once for every copy. In an analogue copier, if you were copying an original that was double sided and had 3 pages, the original document would be scanned for each set you required. This can damage the original set as well as being slower. In a digital copier the original is scanned once into memory and then sets are produced from memory. This makes every copy exactly the same as the first.
