Abstract: An electrostatic color printer having a single toning shoe (17) for successively and sequentially applying color liquid developers to a color latent image overlay to a sheet (13) disposed against a rotating drum (11). An electrostatic head (15) scans the sheet in a helical pattern of abutting stripes (19) and forms the latent image on the sheet. A toning shoe assembly (53) follows the head and applies one of the color developers to the sheet. A drain selector foot (18), pivotable beneath the toning shoe, brings an appropriate developer recycling tube (20) into communication with a drain in the toning shoe assembly. After scanning the sheet, the toning shoe is rinsed with a solvent at a cleaning station (26) past the end of the drum. The toning shoe has a plurality of pressure responsive reed valves (62), each communicating with one of a plurality of channels (92).

Abstract: A toner recycling system (13) having separate supply tank (45) of clear liquid dispersant and tanks (47, 49, 51 and 53) of color concentrate. The liquid dispersant is continuously circulated from its supply tank by a pump (59) along lines (61) to a toner applicator (23) then back to the supply tank. Color concentrate containing charge bearing solid pigment particles is selectively injected and mixed with the dispersant by means of pumps or valves (73) to form liquid toner whenever developing a latent image is desired. The excess toner is collected and sent to a solids separator (63), either dedicated to a particular color of toner or common to all toners, where an electrically biased electrode (79) repels the solid pigment particles toward a particle accumulating surface, thereby separating the particles from the dispersant. The dispersant is returned to the supply tank, while the particles which have accumulated on the surface of either a drum or belt (81) as a layer of concentrate are scraped off by blades (95, 97, 99 and 101) and returned to the appropriate tank.

Abstract: A toner applicator assembly (18) for electrostatic drum printers featuring a toning shoe (17) with a biasing mechanism (32) in which the toning shoe is biased only at a single point (40). The toning shoe scans a sheet (13) having an electrostatic latent image supported on a rotating drum (11), in a helical path, and applies liquid developer to the sheet to develop the latent image. The toning shoe has a normal orientation which is skewed with respect to the drum's rotation axis (z) so as to follow a helical path. The toning shoe is movable with respect to three degrees of freedom ( theta , O &cir& /, psi ) relative to the normal orientation so as to automatically adjust its orientation to match the orientation of the sheet.
