ABSTRACT:
A liquid toner electrophotographic printer includes a movable photoconductor surface, a developer roller, a squeegee roller, a liquid toner cartridge having a supply of liquid toner and a rotatable foam roller, and a transport mechanism including a carriage and air cylinder driven actuation system. The squeegee roller is rotatably mounted on the printer for movement between a first position wherein the squeegee roller is in contact with the photoconductor surface, wherein a drip line of liquid toner forms therebetween, and a second position wherein the squeegee roller is spaced away from the photoconductor. The transport mechanism moves the cartridges between a first position wherein the cartridge foam roller is in contact with the squeegee roller and the developer roller to remove excess liquid toner therefrom and a second position wherein the foam roller is in contact with the photoconductor surface and the squeegee roller, downstream of the squeegee roller, to remove the drip line from the photoconductor surface and the squeegee roller when the squeegee roller is in the second position.
