A simple 2 axis belt system with an attached mechanism to grab and adjust the height of the attached tool. The base functions to hold the extra papers. A screen estimates the time it will take the finish and the USB port would allow the importing of custom instructions through a laptop or flash drive.

The camera scans the current paper and allows the machine to use that information to determine what must be done.
