Abstract

A conventional xerographic laser printer is modified to accommodate laser beam scanning of the toned image from original documents on the photoreceptor surface. The original is fed from a bin that normally holds a copy paper supply and/or traverses the same paper path as sheets receiving print in the printing mode. Printer/scanner 10 (Fig. 1) uses a belt photoconductor 12, which is charged by charge corona 14, and imaged by laser printhead 15 by an image-forming light pattern at imaging area 16. The electrostatic (Image Omitted) image is developed by developer 18, and toner is transferred in the conventional print mode to a copy sheet at transfer station 20 by means of transfer corona 21. The toner is fused to the copy sheet at station 22.
