Abstract

With the advent of commercially available infrared (IR) photoreceptors, the use of a Light Emitting Diode (LED) array to write images on the photoreceptor has taken on renewed interest. As will be understood, arrays of this type comprise one or more linear rows of LEDs in close juxtaposition with one another to form in effect a light bar which, through selective actuation of the individual LEDs in accordance with an image.input signal, exposes the photoreceptor to create or write a latent electrostatic image thereon. The latent electrostatic image created is thereafter processed xerographical I y to produce a permanent visible copy of the image.
