Abstract
An image transfer assembly in a color printer or the like includes four image forming units. Each of the image forming units includes a photoconductive unit and a transfer device. A voltage is applied to the transfer device thereby creating a voltage potential between the photoconductive unit and the transfer device to facilitate the transfer of toner to a media substrate, such as paper. The transfer devices in the first two image forming units share a single high voltage power supply while separate high voltage power supplies supply the necessary voltage to the transfer devices of the other two image forming units.
