    摘要： A phase-change ink transfer printing process and apparatus (10) applies a thin layer of a liquid forming an intermediate transfer surface (12) to a heated receiving surface, such as a drum (14). Then an ink-jet printhead (11) deposits a molten ink image (26) onto the heated drum where it cools to the drum temperature and solidifies. After the image is deposited, a print medium (21) is heated by a preheater (27) to a predetermined temperature and fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23) that is biased toward the drum to form a nip pressure that is about twice the yield strength of the ink image. As the drum turns, the heated print medium is pulled through the nip to transfer and fuse the ink image to the print medium. When in the nip, heat from the drum and print medium combine to heat the ink in accordance with a process window (90), making the ink sufficiently soft and tacky to adhere to the print medium but not to the drum. When the print medium leaves the nip, stripper fingers (24) peel it from the drum and direct it into a media exit path.

    摘要： An apparatus and method are described for applying an intermediate transfer surface, in the form of a liquid layer, on a support surface that may be used in a phase change ink printing system. The apparatus includes an applicator assembly with a leak-free valving system for distributing the liquid layer onto the support surface to produce the intermediate transfer surface and a means for metering the liquid layer uniformly on the support surface. The applicator assembly has a wick contact surface for removing foreign matter from and delivering the liquid onto the support surface. An improved liquid dispensing system is provided to provide the liquid to the wick which becomes saturated and, when brought into contact with the rotatable support surface of a transfer drum, applies the liquid in a layer to the support surface to form a liquid intermediate transfer surface.

    摘要： An improved solid ink stick melt plate design is provided for a solid ink color printer which reliability melts solid ink sticks on demand fed from an ink stick loading bin to ink stick melt plates. The melt plates guide the molten ink into individual color ink reservoirs in the printer print head. The improved melt plate design employs a positive temperature coefficient resistor to prevent the melt plate temperature from becoming too high when not in contact with an ink stick.

    摘要： A compact ink jet print head has cross-sectionally tapered ink manifolds (16) for supplying ink to ink supply channels (18) leading to the acoustically driven ink pressure chambers (22). An array of closely spaced nozzles (14) which are supplied with ink from the densely packed ink pressure chambers by way of offset channels (71). The tapered manifolds, ink supply channels, pressure chambers, and offset channels are designed to provide uniform operating characteristics among the ink jet nozzles of the array. To enhance the packing density of the pressure chambers, the ink supply channels leading to the pressure chambers and offset channels are positioned in planes between the pressure chambers and nozzles. The tapered ink supply manifolds enhance purging of contaminants or bubbles from the print head by providing uniform ink flow rates (97, 97') along the entire length of the manifolds. Optional ink purging channels (42) are provided for purging bubbles and other contaminants from the print head without requiring ink flow through the nozzles. The ink jet print head may be assembled from multiple plates with features in all but the nozzle-defining plate being formed by photo-patterning and etching processes without machining or other metal working.
