摘要： A fluid-ejection printhead die includes first fluid-ejection nozzles, second fluid-ejection nozzles, and a mixing barrier. The first fluid-ejection nozzles eject fluid of a first type, and are organized over a first row and a second row non-collinear to the first row. The second fluid-ejection nozzles eject fluid of a second type different than the first type, and are organized over a third row and a fourth row non-collinear to the third row. The fourth row is at least substantially collinear to the first row. The mixing barrier is at least substantially between the first row of the first fluid-ejection nozzles and the fourth row of the second fluid-ejection nozzles.

摘要： A disposable/refillable inkjet cartridge with bubble generator and an adhesively attached bubble generator vent cover. The cartridge is filed through a bubble generator opening in the cartridge bottom eliminating a separate filling orifice and easing the priming operation. The vent cover is adhesively attached making removal for refilling easier and avoiding suspected problems related to welding flash in welded vent covers. The bubble generator includes a tapered opening which receives a ball. The ball contacts ribs extending longitudinally along a tapered portion of the opening. The ribs are spaced over an arc of the opening. A bubble forms as needed between the ball and opening to maintain back pressure. The ribs and taper produce more consistent bubble pressures. A single piece of tape over the bubble generator and printhead nozzles avoids common causes for depriming.

摘要： In one embodiment of the invention, a flexible tape has formed on it conductors for being connected to a printhead substrate. The conductors on the tape are coated with an insulating layer, and exposed ends of the conductors extend from the layer. A headland is formed on a plastic print cartridge for receiving the printhead substrate having the exposed conductors extending from one or more edges of the printhead substrate. An adhesive bead is formed on the headland so that when the printhead is properly positioned on the headland, the adhesive contacts the conductors to encapsulate and insulate one exposed side of the conductors. A second adhesive or encapsulant bead is deposited over the opposite side of the conductors to encapsulate and insulate the remaining exposed regions of the conductors. In this manner, the combined insulating action of the insulating layer and the two insulating adhesive beads prevents the conductors from being shorted together by ink which may flow in the vicinity of the conductors.

摘要： An ink jet printing apparatus that includes a springbacked fluid interconnect seal that provides a seal between an ink handling component and an ink pipe that is attached to the ink handling component. The spring-backed fluid interconnection seal more particularly includes a generally conically tapered resilient seal, and a pre-loaded spring configured to axially extend or tension the seal. An exemplary embodiment of the invention includes a groove in the sealing face which allows the use of a liquid sealant. The groove holds the sealant in place through capillary forces, and also by virtue of trough-like shape protects the sealant from being wiped away through mechanical member.
摘要翻译：一种喷墨打印设备，其包括回弹的流体互连密封件，其在墨水处理部件和附接到墨水处理部件的墨水管之间提供密封。更具体地，弹簧支撑的流体互连密封件包括大致锥形的锥形弹性密封件，以及构造成轴向延伸或张紧密封件的预加载弹簧。本发明的示例性实施例包括在密封面中的允许使用液体密封剂的凹槽。槽通过毛细管力将密封剂保持在适当的位置，并且由于槽形形状保护密封剂免受通过机械构件的擦去。

摘要翻译：具有气泡发生器的一次性/可重新填充的喷墨墨盒和粘附附着的气泡发生器排气盖。墨盒通过墨盒底部中的气泡发生器开口进入，消除了单独的填充孔，并缓和了起动操作。通气盖被粘附附着，更容易取出以便重新填充，并避免与焊接通风盖中的焊接闪光相关的可疑问题。气泡发生器包括接收球的锥形开口。球接触肋沿开口的锥形部分纵向延伸。肋在开口的弧上间隔开。根据需要在球和开口之间形成气泡以保持背压。肋和锥形产生更一致的气泡压力。气泡发生器和打印头喷嘴上的一条胶带避免了常见的脱色原因。
