Abstract

In an electrophotographic printing machine, four developer units are mounted on a shuttle which translates. Each developer unit stores a different color supply of liquid ink. The shuttle oscillates back and forth to position different developer units adjacent the photoconductive drum having the latent image recorded thereon. In this way, successive latent images are developed with different color liquid inks. While one developer unit is performing the development function, the other developer units may be undergoing cleaning to remove any toner deposited on the electrode. Since each developer develops the latent image in the same space relative to the photoconductive drum, all of the developer units occupy less space than four separate developer units positioned about the circumference of the photoconductive drum. The development region can be optimized for fluid flow and photoreceptor dark decay.
