Abstract
A xerographic printer especially suitable for printing copies of oversized original documents is enabled by staggering a plurality of image bars in optical alignment with a linear projection means such as gradient index lens arrays which are tilted at a preferred angle. The image bars are selectively addressed in response to digitized bit-mapped data inputs representing the document information. The modulated light outputs from the bars are transmitted as focused lines on the surface of the photoreceptor. The printer includes illumination lamps and a lamp aperture which parallels the staggered image bars. Further, a multi-function copier/printer is realized by combining a variation of the xerographic printer with a conventional imaging system for copying a document.
