ABSTRACT:
An electrostatic color printer or copier having a single toner applicator with a system for continuous toner purification. The single applicator is used for each color sequentially and as toning of one color is completed a volume of spent or contaminated toner fluid is left behind in the applicator. This volume is removed with clean wash fluid and sent to a wash fluid tank. Dirty wash fluid is continuously purified either before or after return to a wash fluid supply tank. In the latter case, the wash fluid supply becomes contaminated but is purified as wash fluid is withdrawn or while still in the tank. Continuous purification of dirty wash fluid allows a small volume purifier to be used without need for spent toner disposal.
