Abstract
In a multi-color electrophotographic reproduction apparatus employing a non-impact electro-optic exposure source, good color balance is obtained by changing the exposure intensity of the recording elements for each different color being imaged. A dot printer apparatus produces a series of different color-resolved electrostatic latent images on a recording member. The apparatus includes an array of discrete elements for dot recording on the recording medium. The elements are selectively enabled for predetermined periods of time during a cycle of operation to form a color-resolved electrostatic latent image on the recording member. Each charged latent image is developed with selected toner particles according to its resolved color. A control signal representative at least in part of the resolved color of each latent image is produced, and the control signal determines the intensity of the elements during each cycle of operation according to each resolved color. The intensity is changed by modifying a voltage bias in a current mirror regulated current driver.
