    • A dye transfer ribbon (1) comprises a supporting substrate (2) and a relatively thick dye layer (3) consisting of a dye dispersed within a dye binder. A modulated scanning laser beam (7) heats selected pixel regions of the ribbon (1) and causes dye to diffuse from these regions to the receiver sheet (5) and print a number of pixels thereon which build up to form an image (sublimation transfer is also possible). In order to allow the ribbon (1) to be reused, and so not waste the ribbon or the untransferred dye, the ribbon (1) is passed between a pair of heated rollers (8a, 8b) to cause dye in the dye layer (3) to diffuse to an even density, so that the regions depleted of dye during the print process are replenished, and so that the ribbon may be reused. Instead of the replenishment dye coming from the body of the ribbon (1), it may come from a separate source. The ribbon (1) may be replaced by a dye sheet or a pad, such as a roller, and provision may be made for colour printing.
    • 染料转移带(1)包括支撑基材(2)和由分散在染料粘合剂中的染料组成的相对较厚的染料层(3)。 调制扫描激光束(7)加热色带(1)的选定像素区域,并使染料从这些区域扩散到接收片材(5),并在其上打印其上形成图像的数个像素(升华转印 也是可能的)。 为了使带(1)重新使用,因此不会浪费色带或未转印的染料,色带(1)在一对加热辊(8a,8b)之间通过,从而在染料层中引起染料( 3)扩散到均匀的密度,使得在印刷过程中耗尽染料的区域被补充,并且使得色带可以被再次使用。 代替来自带(1)的主体的补充染料,其可以来自单独的来源。 带(1)可以由染色片或诸如辊的垫替代,并且可以进行彩色印刷。

    • A shutdown procedure is provided for removing all solvent ink from the printhead of an ink jet printer system that uses volatile ink for printing a shutdown method is provided for an inkjet printer that uses volatile inks for printing. Initially, a colorless flush fluid is provided which readily dissolves the ink. The flush fluid is crossflushed through the drop generator and caused to weep out of the orifices in the drop generator to dissolve and rinse away ink residues from the charge plate and the exterior of the orifice plate. The flush fluid is used to rinse off charging electrodes of the charge plate, the catcher face, and the catcher return line. Fluid crossflushed through the drop generator cleans the interior of the drop generator and cleans the crossflush valve.
    • 提供了一种关闭程序,用于从使用挥发性油墨印刷的喷墨打印机系统的打印头中除去所有溶剂油墨,为使用挥发性油墨进行打印的喷墨打印机提供关闭方法。 最初,提供了一种易于溶解油墨的无色冲洗流体。 冲洗流体通过液滴发生器被十字冲洗,并从液滴发生器中的孔中流出,以溶解并冲洗从填充板和孔板的外部的墨水残余物。 冲洗液用于冲洗充电板,捕集器面和捕集器返回线的充电电极。 通过液滴发生器十字冲洗的流体清洗液滴发生器的内部并清洁十字冲洗阀。

    • An automatic start-up for a continuous ink jet printer provides a dyeless flush fluid to the printhead to remove any particles or ink residue from the printhead and to wet the orifice plate before jets form. The pressure of the flush fluid is then raised to cause the flush fluid to begin jetting from the drop generator. Once jets are established, ink is supplied to the drop generator at the pressure of the jetting flush fluid. The flow of flush fluid is stopped. Since the printhead is being supplied with ink, ink replaces the flush fluid as the fluid being jetted from the drop generator. An ink heater is then turned on, increasing evaporation of solvent from the ink jetted from the drop generator. The solvent vapors condense on the relatively cool charge plate and catcher face. The condensate forming on these surfaces provides one final rinse of these surfaces to remove conductive ink from the charge leads and catcher face. After a period of condensate cleaning, the ink heater is turned off, and a heater attached to the charge plate catcher assembly is turned on to dry the charge plate and catcher. Charge voltage may then be turned on to deflect the ink drops into catch. At this point, the printhead is ready for printing.
    • 用于连续喷墨打印机的自动启动为打印头提供了无染的冲洗流体,以从打印头中除去任何颗粒或油墨残余物,并在喷嘴形成之前润湿孔板。 然后冲洗流体的压力升高以使冲洗流体从液滴发生器开始喷射。 一旦建立喷嘴,在喷射冲洗流体的压力下将油墨供应到液滴发生器。 冲洗液的流动停止。 由于打印头被供应墨水,所以当从液滴发生器喷射的流体时,油墨替换冲洗流体。 然后打开一个墨水加热器,增加从滴液发生器喷射的墨水中溶剂的蒸发。 溶剂蒸汽冷凝在相对较冷的充电板和捕集器面上。 在这些表面上形成的冷凝水可以提供这些表面的一次最后漂洗,以从电荷引线和捕集器表面去除导电油墨。 经过一段时间的冷凝清洁后,关闭墨水加热器,打开附着在充电板捕集器组件上的加热器,使充电板和捕集器干燥。 然后可以接通充电电压以将墨滴偏转到捕捉中。 此时,打印头已准备好进行打印。
