It seems redundant to have a copier make multiple passes scanning a document when it is making more than one copy, especially with the new digital copier technology. This invention is a copier that prints its multiple copies from memory instead of scanning the document each time for a copy. By scanning the document only once, the speed of the copier is increased, as is the ease of making double-sided copies. To make ten double sided copies, contemporary copiers must scan the first side of the copy ten times, store the copy internally, and then flip the paper over and start the process again for the other side of the paper. With this new system, the copier could scan the first side into memory, flip the paper over and scan the second side into memory, and then print both sides from memory without having to store the paper internally. Not only will this allow for greater printing speeds, but it will also allow for more simple copying - the need to store and manage more than one piece of paper at a time will be eliminated.
