Abstract: An optical system is provided for a reproducing machine which scans an object to be reproduced, utilizing a pulsing light source to illuminate successive incremental portions of the object. The ray reflected from the scanned image is directed along an optical path onto the imaging plane. The scanned image is directed onto the imaging plane by a reflector element which has an active slit formed on its surface. The reflector element is positioned an optimum distance from the imaging plane such that the image is defocused at more than one magnification ratio.

Abstract: A charge scorotron having a U-shaped shield positionable opposite a photoreceptor, a corona discharge wire in the shield, a grid between the wire and the photoreceptor for controlling the emission of ions to the photoreceptor, the grid being electrically subdivided into a first grid segment with a length substantially equal to the dimension of the smallest size copy sheet with subsequent grid segments having lengths chosen when combined with the first grid segment and each other to substantially equal various larger size copy sheets, switches responsive to the position of an adjustable sheet guide in the copy sheet supply tray connecting each of the other grid segments with the grid bias selectively, the switches when not actuated coupling the grid segment associated therewith to ground whereby the area of the photoreceptor charged is determined by the number of grid segments coupled to the grid bias in response to the size copy sheet being processed.

Abstract: An apparatus and method for developing an electrostatic latent image on an imaging member wherein a development nip is formed between a rotatably mounted cylindrical developer roll and the imaging member. The nip is initially supplied with a wedge shaped layer of developer material to develop the electrostatic latent image on the imaging member. Periodically at stated intervals the developer material is collected from the developer roll and development nip and the same measured amount of developer material is resupplied to the development nip. The apparatus includes a developer material supply means comprising a developer material hopper having a dispensing aperture at the bottommost portion thereof adjacent the developer roll, a movable dispensing slide in operative association with the developer material hopper, the slide having in succession a solid portion for sealing association with the aperture in the hopper, an aperture for dispensing association with the aperture in the hopper and the cleaning doctor blade for cleaning engagement with the developer roll to collect developer material in the pile as the slide is movable back and forth from sealing association with the hopper aperture and for cleaning the developer roll.
