Abstract

A multi-mode color copier having a photoreceptor for storing color separated images. The color copier includes a platen input for transmitting color images from an original to the photoreceptor, a raster output scanner for writing on the photoreceptor and a raster input scanner for reading developed color separated images from the photoreceptor. The input to the raster output scanner and the output from the raster input scanner are in the form of digitized video signals which correspond to the color separated images. In addition to outputting video signals through the raster input scanner the copier can create color copies by sequentially transferring developed images from the photoreceptor to a copy sheet and fusing those images to form a permanent color copy.
