    • In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. The print cartridge contains a regulator valve. An ink tube extends from the scanning carriage to a separate, disposable ink supply cartridge located within the printer. A second valve connected between the ink tube and the ink supply cartridge is automatically actuated when it is determined that the printer is not being used. The valve seal is more reliable than the inexpensive one-way valve seal in the disposable ink supply cartridge. The reliable valve seal prevents any air bubbles in the tube from expanding toward the ink supply cartridge, enabling the use of more flexible tubes which have less stringent air diffusion characteristics. In another embodiment, instead of a valve, a pressure source is connected to the ink tube to maintain the partial air pressure within the tube at approximately ambient pressure.
    • 在优选实施例中,喷墨打印机包括插入到扫描托架中的可替换打印盒。 打印碳粉盒包含一个调节阀。 墨水管从扫描托架延伸到位于打印机内的单独的一次性墨水供应盒。 当确定打印机未被使用时,连接在墨水管和供墨盒之间的第二阀被自动启动。 阀密封件比一次性供墨盒中便宜的单向阀密封件更可靠。 可靠的阀密封防止管中的任何气泡朝向墨水供应墨盒扩张,从而能够使用具有较不严格的空气扩散特性的更柔性的管。 在另一个实施例中,代替阀,压力源连接到墨管,以将管内的部分空气压力保持在大约环境压力。

    • Described is an ink delivery system for an inkjet printing system including a housing; a printhead fixed to the housing for ejecting droplets of ink on media; a regulator located within the housing; a source of ink for replenishing the printhead; and an ink passageway for connecting the source of ink and the valve inlet. The regulator including a valve having an inlet and outlet, with the outlet in fluid communication with the printhead; a flexible member within the print cartridge, the flexible member has a reference surface and an ink surface, the reference surface is in communication with an outside atmosphere, the ink surface is in fluid communication with the printhead, the difference in pressure between the outside atmosphere and the printhead causes the flexible member to bias toward the ink surface; and an actuator that is receives a force from the ink surface of the flexible member, the actuator actuates the valve based upon the differential pressure between the reference surface and the outside atmosphere. Also described is a fluidic coupling that releasably and fluidically connects to the inlet port of a print cartridge. The fluidic coupling acts as a seal for the print cartridge and a means of lubricating and protecting the inlet port from drying, leaking ink, and air ingestion while the print cartridge is in transit and in storage. The fluidic coupling also provides an auxiliary ink reservoir for the print cartridge. The fluidic coupling further provides an ink conduit to the printhead from an external ink supply.

    • Disclosed is an ink delivery system for high throughput commercial inkjet printing devices. The ink delivery system includes a high speed ink ejection printhead with a large number of nozzles and an ink flow design which provides for improved printhead cooling. The printhead design achieves high ink ejection rates by having a very short inlet channel length which is made possible by having nozzles with a constant distance from the edge of the printhead. In order to accommodate this constant distance from the edge of the printhead the entire array of nozzles is disposed at a angle relative to the direction normal to the scan direction. An impinging ink flow against the back of the printhead is provided to limit the temperature of the printhead. A bubble collection chamber to increase the life of the printhead and a pressure regulator to provide ink at a controlled pressure to the printhead may also be provided. Pressurized ink may be provided so that ink pressure may be properly controlled even during peak usage.
    • 公开了一种用于高通量商用喷墨打印设备的墨水输送系统。 墨水输送系统包括具有大量喷嘴的高速喷墨打印头和提供改进的打印头冷却的油墨流动设计。 打印头设计通过具有非常短的入口通道长度实现了高的喷墨速率,这通过具有距离打印头边缘恒定距离的喷嘴而实现。 为了适应距离打印头边缘恒定的距离,整个喷嘴阵列相对于垂直于扫描方向的方向成一角度设置。 提供抵靠打印头背面的冲击墨水流动以限制打印头的温度。 也可以提供一种用于增加打印头寿命的气泡收集室和压力调节器,以便在受控压力下向打印头提供墨水。 可以提供加压油墨,使得甚至在峰值使用期间也可以适当地控制油墨压力。

    • Disclosed is a replaceable ink container for providing ink to an ink-jet printing system. The ink container includes a pressure vessel for pressurizing ink. The ink container has a non-operating state and an operating state. Within the operating state, the pressure vessel has an internal gauge pressure maintained within an operating range so that pressurized ink is provided to the printing system. The ink container also includes a gas vent apparatus communicating between an inside surface of the pressure vessel and an outside atmosphere to allow continuous venting in both the operating and non-operating states. In one preferred embodiment the vent apparatus includes a porous member that is located between a pressurized region of the ink container and an outside atmosphere. This porous member provides a flow path for gas therethrough.
