ABSTRACT:
A printer has a print cartridge with a plurality of electrically isolated screen electrodes extending in parallel strips and maintained at different potentials to define a uniform electric field in the gap between a print cartridge and a latent imaging member curved about an axis parallel to the strips. As charge carriers are generated, the potentials on a plurality of control electrodes located between the charge carriers and overlying screen electrodes are controlled to provide a fixed bias. This assures gating of a uniform quantity of charge from different apertures of the print cartridge, as well as uniform size of the charge dots formed on the imaging member.
