    摘要： A phase change ink transfer printing apparatus (10) applies a liquid intermediate transfer surface (12) to a heated drum (14, 28). Because the intermediate transfer surface is a thin liquid layer, molten ink drops (122) striking it flatten and spread out (110, 112, 114, 130) prior to cooling and solidifying as an ink image (26, 130) at the drum temperature. After the ink image is deposited, a print medium (21, 132), such as a transparency film, is fed into a nip (22) formed between the heated drum and an elastomeric transfer roller (23). As the drum turns, the print medium is pulled through the nip to transfer 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. The ink drops comprising the ink image have a desired diameter to height ratio of from about 1.5:1 to greater than about 4:1 using the apparatus and method of printing disclosed. When the print medium leaves the nip, stripper fingers (24) peel it from the drum and direct it into a media exit path. No image post processing or fusing is necessary to achieve a high-quality print suitable for transparency projection.

    摘要： An ink stick for a solid ink feed system of a phase change ink printer includes an ink stick body having an insertion perimeter, and a guide surface with a shaped guide element shaped to interact with an elongate shaped guide rail of the solid ink feed system. The ink stick insertion perimeter is in a plane substantially perpendicular to the insertion direction, and the insertion direction and the feed direction are different. The insertion perimeter has at least one perimeter section forming a nonlinear key element that matches in size and shape a nonlinear key element in the perimeter of the key plate insertion opening. In particular implementations, the insertion perimeter forms a visually recognizable symbol, such as an alphanumeric character. In particular implementations, a plurality of ink sticks form a set in which the visually recognizable symbols differ from one another, and may form a pattern of symbols, such as a sequence of alphanumeric characters.

    摘要： A process motor (82) provides bidirectional motive force to a printer (50) drive train (80) that selectively engages with multiple self-homing printing functions. A print head (52) is tiltable to a maintenance position and a transfer roller (64) is loadable against a transfer drum (54) by respective missing tooth gear (96, 160) latching mechanisms. A print media pick roller (122) and transfer drum maintaining devices (70, 72) are actuated by spring-wrap clutches (114, 236) that are protected from reverse rotation by a one-way clutch (106). Print media transport rollers (140, 142) are selectively engaged with the one-way clutch by an electro-mechanical clutch (128). A picked and transported print medium (56) receives an ink image from the transfer drum and is stripped therefrom by stripper fingers (66) and directed into media exit rollers (212, 220) for delivery to a media output tray (68). The stripper fingers and exit rollers are actuated sequentially by cams (180, 182) that are slaved to the transfer roller loading function.

    摘要： An ink stick for use in a solid ink feed system of a phase change ink jet printer includes an ink stick body. Nesting elements are formed in the ink stick body for nesting the ink stick body with an adjacent ink stick body. One end surface of the ink stick body has a projecting nesting element, and the opposite end surface has a recessed nesting element having a complementary shape and position. When two ink sticks with such nesting elements abut one another in a feed channel of a solid ink feed system, the projecting nesting element of one ink stick fits into the recessed nesting element of the adjacent ink stick to reduce movement of the ink sticks relative to each other, and to reduce skewing of the ink sticks in the feed channel.

    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： A print drum and associated clamping assembly is provided for use in printing or similar operations. The print drum is characterized by uniform thermal characteristics and is constructed from a material having thermal diffusivity of greater than about 1.3.times.10.sup.-5 m.sup.2 /sec. The print drum may moreover have a highly reflective surface that permits optical sensors to distinguish between the drum and substrate surfaces. Clamping sections of a substrate clamp assembly project through slots provided in the print drum and are raised and lowered to release and clamp a substrate respectively. Other constituents of the clamp assembly are mounted in the hollow interior of the print drum. The print drum and associated clamping mechanism is especially suitable for use in ink jet printing apparatus utilizing thermal phase change inks.

    摘要： An ink stick for use in a solid ink feed system of a phase change ink jet printer includes a three dimensional ink stick body that has a lateral center of gravity, a substantially horizontal perimeter, and opposed end surfaces. An ink stick guide element is formed in the bottom of the ink stick body, and the ink stick is adapted to travel through the feed channel along a feed channel guide rail. A portion of the ink stick perimeter forms a visually recognizable symbol, and a portion of the ink stick perimeter that is transverse to the feed direction of the channel has an insertion key element. Nesting elements are formed in the leading and trailing end surfaces of the ink stick body to nest with one another when ink sticks abut in the feed channel.
