摘要： The present invention overcomes the problem of filter blockage created by bubble accumulation underneath the filter of previous printheads with a filter carrier and filter that reduces air bubble blockage of the filter. Namely, air bubble blockage of the filter is avoided by trapping more bubbles in a designated area with a horizontal ink flow, relative to the substrate. In addition to the filter carrier and filter, the printing device further includes an outer housing, a substrate and an ink conduit. The substrate has a back surface and a front surface with ink ejection chambers formed thereon. The ink conduit has a distal end proximate to the back surface of the substrate. The ink conduit, the outer housing and the substrate define an ink flow path to the ink ejection chambers and a bubble accumulation chamber in communication with the ink flow path such that buoyancy will tend to move bubbles that accumulate in the ink flow path into the bubble accumulation chamber.
摘要翻译：本发明克服了使用过滤器载体和过滤器的过滤器下面的气泡积聚产生的过滤器阻塞的问题，该过滤器载体和过滤器减少了过滤器的气泡阻塞。也就是说，通过在相对于基板的水平墨水流动的指定区域中捕获更多的气泡来避免过滤器的气泡堵塞。除了过滤器载体和过滤器之外，打印装置还包括外壳体，基底和墨水导管。基板具有背面和形成有喷墨室的前表面。墨水导管具有靠近基底的后表面的远端。墨水导管，外壳体和基底限定到墨水喷射室的墨水流动通道和与墨水流动路径连通的气泡积聚室，使得浮力将趋向于移动在墨水流动通道中积聚到气泡中的气泡积聚室。

摘要： This present invention is embodied in a printing system with thermally efficient heat transfer capabilities for reducing dimpling of a nozzle member during fabrication of the printhead portion of an inkjet printer. The printing system of the present invention includes a printhead assembly and an ink supply for printing ink on print media. The printhead assembly includes a printhead body having a heat transfer device, ink channels and a nozzle member having plural nozzles coupled to respective ink channels. The nozzle member is secured to the printhead body with a suitable adhesive layer. The heat transfer device can be defined by a portion of or the entire printhead body for reducing thermal expansion of the printhead body during exposure to heat. Namely, the heat transfer device of the printing system of the present invention is capable of efficiently reducing thermal expansion of the printhead body during the process of adhering (which includes heating and curing the adhesive) the nozzle member to the printhead body. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.

摘要： This present invention is embodied in a printing system and method for inducing shrinkage-tensioning of a flexible nozzle member of a printhead portion of an inkjet printer with an adhesive and novel arrangement. The printing system of the present invention includes a nozzle member securely coupled to a printhead body with an adhesive arrangement that allows shrinkage-induce tensioning of the nozzle member. The adhesive arrangement includes having an adhesive located between a top portion of the printhead body and the flexible nozzle member. The top portion has a mechanical structure such that it induces tensioning of the flexible nozzle member during thermal expansion of the adhesive. Namely, the adhesive arrangement of the printing system of the present invention is capable of efficiently tensioning, and thus, flattening the flexible nozzle member during the adhesion process of the nozzle member. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.

摘要： A print module includes a printhead die, an input regulator to regulate input fluid pressure to the die, and an output regulator to regulate output fluid pressure from the die. A method includes receiving fluid at an input regulator to a print module, creating a fluid pressure differential within the print module between the input regulator and an output regulator, flowing fluid from the input regulator through a printhead die and to an output regulator using the pressure differential, and drawing fluid from the output regulator.

摘要： A modified syringe for recharging an ink supply in a print cartridge is described. In the preferred embodiment, the end of a syringe valve is inserted into the end of a print cartridge valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further insertion causes both valves to become open, thus creating an airtight fluid path between the syringe chamber and the depleted print cartridge reservoir. A negative pressure within the print cartridge ink bag draws the ink from the syringe chamber into the ink bag until the ink bag is substantially full and the pressure in the ink bag is at or near atmospheric pressure. An air intake port is provided on the syringe to fill the void left by the ink in the syringe chamber. Once the print cartridge has been recharged, a plunger in the syringe is manually pulled back a predetermined distance to draw an amount of ink out of the print cartridge to create the desired negative pressure in the print cartridge. The syringe is then removed from the print cartridge, automatically pulling the two valves closed.
摘要翻译：描述了用于对打印墨盒中的墨水供应进行再充电的改进的注射器。在优选实施例中，注射器阀的端部插入打印墨盒阀的端部，以在两个阀之间产生机械联接和流体密封连接。进一步的插入导致两个阀打开，从而在注射器室和耗尽的打印墨盒储存器之间形成气密的流体路径。打印墨盒墨水袋内的负压将墨水从注射器室吸入墨水袋中，直到墨水袋基本上充满并且墨水袋中的压力处于或接近大气压。在注射器上设置有一个进气口，以填充注射器腔中的油墨留下的空隙。一旦打印墨盒已被充电，将注射器中的柱塞手动地拉回预定距离，以将一定量的墨水从打印墨盒中取出以在打印墨盒中产生所需的负压。然后将注射器从打印碳粉盒中取出，自动将两个阀关闭。

摘要： A print cartridge is described which has an ink recharge port and valve structure to enable the print cartridge reservoir to be recharged with ink. A slideable, generally cylindrical ink valve extends through the print cartridge body and into the ink bag. The valve has a male connector portion at its end external to the print cartridge body. The valve is open when pushed into the print cartridge body and closed when pulled away from the print cartridge body. An ink refill system containing a supply of ink has a slideable valve with a female connector portion which is engageable with the male connector portion of the print cartridge valve. To recharge the print cartridge ink reservoir, the end of the print cartridge valve is inserted into the end of the ink refill system valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further force pushing the print cartridge against the ink refill system causes both valves to be pushed inside their respective ink reservoirs. This further insertion causes both valves to become open, thus creating an airtight fluid path between the ink refill system reservoir and the depleted print cartridge reservoir. When the valves are mechanically decoupled, the valves are automatically closed.
摘要翻译：描述了一种打印墨盒，其具有墨水再充电端口和阀结构，以使打印墨盒储存器能够用墨水充电。可滑动的，通常为圆柱形的墨水阀延伸穿过打印墨盒主体并进入墨水袋。该阀在其打印墨盒本体外部的一端具有一个阳连接器部分。当推入打印墨盒主体时，阀门打开，并从打印墨盒主体拉出时关闭。包含油墨供应的墨水补充系统具有可滑动的阀，其具有可与打印墨盒阀的阳连接器部分接合的阴连接器部分。为了对打印墨盒墨水储存器充电，打印墨盒阀的端部插入墨水补充系统阀的端部，以在两个阀之间产生机械联接和流体密封联接。将打印墨盒推向墨水填充系统的另一个力使得两个阀都被推入它们各自的墨水容器内。这种另外的插入导致两个阀变得打开，从而在墨水补充系统储存器和耗尽的墨盒储存器之间形成气密的流体路径。当阀被机械分离时，阀被自动关闭。
