ABSTRACT:
A large scale LED exposure array and system for printers, and unique methods of inputting data to and operating such an array, are disclosed. The array can be loaded and refreshed with data information at rates compatible with high speed printing, and forms part of an electronic image forming and handling system which can load an refresh an exposure array at variable speeds of at least 100 to 300 ft./min. The system includes compensation for differences in illuminating capability of individual LEDs in a large array, by introducing modifications in LED on-time which are centered with respect to the incremental area of the photoreceptor on which a pixel is to be formed, and to compensate for changes in pixel exposure time with increase in speed of the photoreceptor. Also disclosed are an LED configuration which can emit high energy in a controlled pattern to give a desired pixel spot on a photoreceptor, and an arrangement for mounting the array to maintain each light emitting spot in focus on the photoreceptor surface, although a wide array is employed.
