Abstract
A system for forming an image on the outer surface of a plastic card. A toner image on the electrophotographic medium is transferred to a portion of the card through heat and pressure. An improved platen mechanism makes a rolling motion with its arcuate surface to transfer the image to the card. An improved linkage mechanism for operating the platen is shown. A protective layer is placed over the fused toner image.
