  • Patent number: 4330195
    Abstract: A multiple mode image processing apparatus and method. The apparatus, in a copy mode, processes copies xerographically. In a write mode, images derived from image signals are written on the apparatus photoreceptor by a raster scanner, and in a read mode, the raster scanner scans images developed on the photoreceptor to produce image signals representative thereof. A multiple speed drive is provided for the photoreceptor to move the photoreceptor at a high speed when processing copies xerographically and at a lower speed compatible with the data transmission rate for image signals when writing or reading images.
