Abstract
A multicolor imaging device capable of operating at higher than normal speeds when a full range of colors is not required. The imaging device includes four station groups each having a charge scorotron, a light source for exposing a photoconductive belt to a color signal, and a toner developer. When a color of a particular station is not required, the light source for that station is disabled and the charge scorotron of that station is enabled to allow a higher charging rate for the required colors, thereby allowing the belt to be propelled at a higher speed.
