摘要： An inkjet printer includes a plastic platen and a structural member extending upward from the base of the printer. The printing surface is supported by the upper surface of the structural member. This surface is held flat to within very tight tolerances. The bottom of the platen printing surface is retained against this surface so that it conforms to the shape of this surface structural member to create a substantially flat printing surface.

摘要： An ink delivery system delivers ink from a stationary ink supply to a print cartridge on a movable carriage. The system comprises an ink container, a reservoir, and a flexible tubing connecting the reservoir to the print cartridge. The ink container has an internal cavity not open to atmosphere holding a supply of ink, and an air inlet channel and an ink exit channel. The ink reservoir has fluid channels to mate with the air inlet channel and ink exit channel on the ink container, and an air opening on the upper portion to connect the internal space of the reservoir to atmosphere and an ink exit port. The ink level in the ink reservoir is controlled by allowing the ink to rise to a level where the ink blocks the air channel into the ink container thereby preventing air to flow there through.
摘要翻译：墨水输送系统将墨水从固定墨水供应到可移动托架上的打印墨盒上。该系统包括墨水容器，储存器以及将储存器连接到打印墨盒的柔性管道。墨水容器具有不向保持供墨的大气开放的内部空腔，以及进气通道和出墨通道。墨水储存器具有与墨水容器上的空气入口通道和墨水出口通道配合的流体通道，以及在上部的空气开口以将储存器的内部空间连接到大气和墨水出口。墨水容器中的墨水水平通过允许墨水升高到油墨将空气通道插入墨水容器中从而防止空气流过其中的水平来控制。

摘要： A replaceable ink supply tank that can be mounted to a pen body of a printhead system for use with an ink jet printer. The ink supply tank provides the necessary back pressure for successful operation of the printhead and includes a siphon break in the conduit that supplies ink from the supply tank to the pen body. A conduit connects the ink supply tank to the pen body. The conduit contains a raised portion that is at a level higher than the ink level in the supply tank. The conduit contains a siphon break chamber between the raised portion and the pen body. The conduit further contains an accumulator in the raised portion of the supply tank. The accumulator maintains back pressure in the preferred range to discourage drooling from the nozzle plate during ambient temperature swings.
摘要翻译：可更换的墨水供应罐，其可以安装到打印头系统的笔体上，以便与喷墨打印机一起使用。墨水供应罐为打印头的成功运行提供必要的背压，并且在导管中包括虹吸断裂，其将墨从供应罐供应到笔体。导管将供墨箱连接到笔体。导管包含一个高于供应罐中的墨水量的升高部分。导管在凸起部分和笔体之间包含虹吸断裂室。导管还包括在供应罐的凸起部分中的蓄压器。在环境温度波动期间，蓄能器将背压保持在优选的范围内以阻止从喷嘴板流出。

摘要： A device and method for supplying ink to ink jet printer heads comprising first and second carriage portions non-rigidly coupled such that the two carriage portions are free to rotate independently about their guide rod axis, but are constrained to move together axially. The first carriage portion contains one or more ink jet cartridges supplied with ink via connecting tubes having self-sealing septum attached to corresponding ink outlets on the second carriage portion. The ink outlets on the second carriage portion preferably comprise valves with actuators. The actuators preferably act to secure the septum within the ink outlets, and are preferably disposed such that the valve is closed when the actuator is raised, and open when the actuator is lowered.

摘要： An ink delivery system in an inkjet printer includes a printhead mounted on a carriage in the inkjet printer. The printhead has nozzles to eject ink droplets for image printing. The system includes an ink reservoir for delivering ink to the printhead. The ink reservoir is positioned so that the ink level is from 0 to 8 inches below the printhead. A pulsation dampener is connected between the ink reservoir and the printhead. The pulsation dampener includes two chambers within a body, wherein a weir separates the chambers. A resilient member is located in one of the chambers and a membrane covers the chambers and the resilient member. The resilient member provides a recovering force against the membrane. Embodied herein is a method of delivering ink to a printhead mounted on a movable carriage using the embodied ink delivery system.

摘要： An ink jet printer apparatus is adapted to secure a print cartridge which includes an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head. The ink jet printer apparatus has a resilient septum; an ink delivery connection to the septum; a stall for receiving the print cartridge in a substantially horizontal direction, so that the ink conduit needle mounted on the top cover lid is horizontally inserted through the septum; and a cover door movable closed to cover the print cartridge when the print cartridge is received in the stall, and adapted to secure the print cartridge in place within the stall to ensure that the ink conduit needle cannot be dislodged from the septum.
摘要翻译：喷墨打印机装置适于固定包括具有顶部开口的敞开的容器的打印盒; 容器中的多孔吸墨剂; 与多孔吸墨剂连接的打印头; 顶盖盖，适于放置在容器上，在顶部开口上，以封闭容器; 以及当盖盖放置在容器上时，安装在顶盖盖上的墨水导管在水平方向上纵向延伸，使得打印墨水可以通过重力从墨水中自由下降导管针到多孔吸墨剂上并从多孔吸墨剂向下到达打印头。喷墨打印机具有弹性隔膜; 与隔膜的墨水输送连接; 用于在基本上水平的方向上接收打印墨盒的档位，使得安装在顶盖盖上的墨水导管水平地穿过隔膜插入; 以及当打印盒被接收在档位中时可闭合以覆盖打印盒的盖门，并且适于将打印盒固定在档位内的适当位置，以确保墨水导管针不能从隔膜移出。
