摘要： A specified and designated, non-primary color print (imaging) is applied to a substrate (paper) (43) by mixing at least first and second differently colored toner particles having substantially uniform physical characteristics, and introducing them in desired proportions into a fluidized bed (16). The toner powders are uniformly mixed together in the fluidized bed (as by using rotors (17) in addition to applying fluidizing air to the bed), and then a substantially uniform electrostatic charge (e.g. about +6.5-+8 kV D.C., which can be applied by blades on the rotor) is applied to the bed, and then the electrostatically charged mixture of toner particles is applied to the substrate (43), to image uniform non-primary color symbols on the substrate. The uniform physical characteristics of the powders are size (the vast majority of particles having a size between about 5 µm and about 25 µm), a resistivity of greater than 10¹² ohm-cm, and a flowability between a predefined minimum and maximum. When utilizing the fluidized bed as according to the invention, slight changes in chemical composition of the toners may be easily accommodated without change in the resulting uniform imaging.

摘要： 5 n7 Non-magnetic and non-conductive powdered toner (16) is applied to a rotating image cylinder (41) having an electrostatic pattern. A container (10) having a closed bottom and sides and open top contains the powdered toner. The powder is fluidized by introducing air (at 11) through a pervious closed bottom (13) of the container and by vibrating the container. The toner is simultaneously stirred and electrically charged to a potential of greater than about 7kv (plus of minus polarity) by rotating elements 14) with radial pointed appendages in the container. Toner is transferred from the container to an image cylinder (41) at an exposed nine o'clock position of the image cylinder by a plurality of transfer cylinders (30). A first transfer cylinder (31) is mounted so that its periphery is just above the open top of the container and an applicator cylinder (33) has its axis below the axis of the first cylinder and its periphery adjacent both the first cylinder (31) and the image cylinder (41). A second cylinder (35) is for the removal of opposite sign charged toner and low charge toner from the applicator cylinder. Scrapers (32, 34) scrape unused toner from the first and applicator cylinders so that it falls into the open top of the container. A hopper (20) supplies fresh toner.

摘要： Cleaning apparatus (12) for an imaging cylinder (10) in an ion deposition printer includes a housing (14) having an upper portion (16) and a lower portion (18), separated by an internal plate (22). The lower portion includes a plenum chamber (42) having an opening (40) at one end and a vacuum port (44) at an opposite end, and a scraper blade (24) mounted in the plenum chamber and having an edge engaging the imaging cylinder. A continuous cleaning web (54) is mounted in the upper portion (16) engaging the imaging cylinder downstream of the scraper blade. The cleaning web is impregnated with silicone oil. A related method includes the steps of (a) engaging the peripheral surface of the imaging cylinder with a scraper blade to remove toner particles therefrom; and (b) engaging the peripheral surface of the imaging cylinder downstream of the scraper blade with a continuous web impregnated with oil to remove residual toner particles and conductive powder deposits.
