Abstract

In a copying machine having reduction capability, it is often difficult for a user to select the appropriate magnification for a given document input and copy paper output. In copy machines having magnification, the problem is compounded by the risk of losing wanted data by over filling the copy paper. A platen can be modified to position a series of light-emitting diodes (LEDs) in plastic-edge registration strips to inform the operator of the document format that will be reproduced based on the selected magnification ratio and copy paper size. For example, in a machine having magnification capability ranging from .5x to 1.5x, 100 diodes placed at .1 inch intervals would provide quantized positional information accurate to within 1.2 percent of an 8.5 x 11 inch document.
