摘要： A media preheater positioned in the media path of a printer and having a fixed heater and a movable plate array biased toward the heater such that printing media passing between the heater and the plate array is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing medium. The plate array may be a thermally massive element that contacts the heater when no media is present, thereby permitting the medium to be heated from both sides.

摘要： A method of cleaning a media preheater that is positioned in the media path of a printer is disclosed. The media preheater has a fixed heater and a movable plate array biased toward the heater such that printer media passing between the plate array and the heater is compressed therebetween and heated. The preheater may be positioned upstream of a print head and downstream of a media advancing mechanism in the media path. More than one plate may be provided in the plate array to accommodate non-planarity of the heater or the printing media. The method elevates the temperature of the contact surface of the preheater to a cleaning temperature that is greater than the operating temperature and then passes a chase sheet over the surface to remove contamination from the preheater surface.

摘要： An ink jet array print head (101) includes four media-width linear ink jet arrays (100). Ink flows from four sets of manifolds (106) through acoustically matched inlet filters (116), inlet ports (117), inlet channels (118), pressure chamber ports (120), and ink pressure chambers (122). Ink leaves the pressure chambers through outlet ports (124) and flows through oval outlet channels (128) to orifices (108), from which ink drops (110) are ejected. The ink pressure chambers are bounded by flexible diaphragms (130) to which piezo-ceramic transducers (132) are bonded. To minimize inter-jet cross-talk caused by pressure fluctuations in the manifolds, compliant walls (150) form one wall along the entire length of each manifold. An improved ink feed system (210) supplies four colors of ink to the print head. Phase-change inks are melted and deposited in ink catch basins (202), funneled into ink storage reservoirs (204), and fed to the print head through ink stack feeds (206) having substantially equal lengths and cross-sectional areas to improve jetting uniformity. Manifold tapering, inlet port positioning, and an elevationally upward slope of the ink stack feeds enhances purgeability of the ink feed system and the ink jet print head.

摘要： An improved media-width phase-change ink-jet print had (102) maintains a uniform temperature across its width to produce consistent drop mass and uniform print quality. The print head uses a heater (120) including two separately controlled, overlapping heating zones (154). The heating zones produce heat gradients (170, 172) that have maximum outputs toward opposing edges (168a, 168b) of the print head and are controlled in response to thermistors (138s, 168b) positioned at the corresponding edges. The two heating zones together produce a linear heat gradient (180) across the print heat to compensate for uneven head-to-drum spacing (166) and other unsymmetrical thermal loads on the print head. The improved print head also includes baffles (192) that reduce air flow between the head and the attached reservoir (118), and thermal breaks (218) that insulate the section (220) of the head that includes the jets from the thermal gradients at the edges of the print head.
摘要翻译：改进的介质宽度相变喷墨印刷（102）在其宽度上保持均匀的温度，以产生一致的液滴质量和均匀的打印质量。打印头使用包括两个分开控制的重叠加热区（154）的加热器（120）。加热区产生对打印头的相对边缘（168a，168b）具有最大输出的热梯度（170,172），并响应于位于相应边缘的热敏电阻（138s，168b）来控制。两个加热区域一起在打印热量上产生线性热梯度（180），以补偿打印头上不均匀的头对鼓间距（166）和其他不对称的热负荷。改进的打印头还包括减少头部和附接的储存器（118）之间的空气流动的挡板（192），以及热断裂（218），其将包括射流的头部的部分（220）与热梯度隔离打印头的边缘。
