Abstract
A method and apparatus for recycling marking surfaces such as office paper is described. The system scans a marking surface, determines the location of printing on the marking surface and deposits erasing material directly over the printing. Because the distribution of erasing material is confined to the printed areas, the use of erasing material is minimized. The described system can be easily adapted for use in traditional copying systems to recycle paper.
