  • Patent number: 4602262
    Abstract: This invention relates to a non-impact printer apparatus such as a xerographic, magnetic, or ion deposition type printer in which the image is produced with a plurality of dots, which collectively combine to form the characters of a printed text or plot. The printer includes a dot forming array for selectively generating dots to form a pattern on a rotating transfer drum or belt. The drum having an image on the surface thereof, is adapted to transfer the image onto sheet material. The drum rotates through a plurality of rotations while an image is being formed thereon prior to transferring that image to a sheet. This is accomplished by selectively activating the drum charging mechanism, as well as the drum cleaning and toning mechanisms. The dot forming array may be an array of light emitting diodes and either the array or the drum are shifted between rotations to allow the same dot forming array to transfer dots to a different position during each rotation of the drum.
