ABSTRACT:
An electrostatic color printer or copier which uses a single pump for controlling fluid toner at low flow velocities and a separate pump or blower for an air jet used to expel fluid from common passages between applications of different colors. A full width toning applicator admits toner and air in a manner so that air limits flow of toner beyond the applicator. During a purging cycle, more air is admitted, forming an air jet which blasts surfaces and passages clear of liquid.
