Abstract
A non-contact LED-array image printer is provided having a scanning print head driven by a zero backlash threaded lead screw. The LED array is mounted on a substrate bearing an interface control circuit which receives video data through a ribbon cable, and the LED array is imaged by a lens onto an exposure plane on a platen parallel to the direction of scan. Means are provided for conveniently adjusting object and image distances relative to the image plane. The photosensitive medium is driven in registration in forward and reverse directions biased against the exposure platen defining the image plane. A gear, clutch and brake mechanism is provided to ensure that the photosensitive medium remains in taut registration across the exposure platen.
