摘要： A method of reducing air in an ink passageway in an inkjet printer by pressurizing a thermally actuated degassing unit that includes an air chamber, venting air through a check valve configured to allow air to vent from the air chamber to ambient when the pressure in the air chamber exceeds ambient air pressure by a predetermined amount The pressurizing is performed by heating an element inside the air chamber. A power supply is connected to the heating element, and power is applied to the heating element during a first time interval to increase the pressure in the air chamber above ambient pressure. Gas is vented from the check valve which allows the heating element to cool during a second time interval to reduce the pressure in the air chamber below ambient pressure. Gas is then drawn from the ink passageway through the membrane into the air chamber.

摘要： The present invention relates to a method that enables image quality of a printed image to be maintained by reducing unintended variations in drop volume, through the adjustment of ink drop ejecting conditions depending on the amount of ink remaining in an ink tank chamber or reservoir, and/or the ink demand for printing an image. The method of printing of the present invention comprises: providing a printhead in fluid communication with an ink chamber or reservoir; detecting at least one parameter related to an amount of negative pressure provided to the printhead; and adjusting an ink drop ejecting condition of the printhead as a function of the parameter so that an amount of variation in size of ejected ink drop is reduced.

摘要： A printing system includes a movable tray for holding recording media. The movable tray includes spaced-apart reference marks for determining distance traveled by the tray. A reference-mark optical detector is positioned to provide a field of view through which the reference marks pass. An identifying-mark optical detector provides a field of view through which media-type identifying marks on a piece of recording medium pass. A signal processor provides an output relative to: a) amount of reference marks passing through the field of view of the reference-mark optical detector, and b) signal variation in a signal provided by the identifying-mark optical detector. A look-up table includes media identification signal patterns that are correlated to corresponding media types. Finally, a comparator compares the output of the signal processor to the media identification signal patterns in the look-up table in order to identify type of recording medium.

摘要： An internal filter includes a lower substrate and an upper substrate. Fluid passages are formed by etching grooves into the surface(s) of the upper and/or lower substrates and/or in one or more intermediate layers. The filter pores extending between the fluid passages are formed by etching second grooves that fluidly connect the fluid passages. Two or more sets of the one or two intermediate layers can be implemented to provide additional filter passages and/or pores. Each set can be connected to a separate fluid source and/or a separate microfluidic device. In another internal filter, the inlet and outlet passages and the filter pores are formed on the same upper or lower substrate. The inlet and outlet passages are partially formed in a first step. In a second step, the inlet and outlet passages are completed at the same time that the filter pores are formed.

摘要： A printhead uses large and small drop ejectors to achieve efficient gray scale printing. The printhead is arranged with a close packed configuration of alternating large and small nozzles positioned to maximize coverage while minimizing the volume of ejected ink. The printhead may be operated in a single pass mode or dual pass mode. In the single pass mode, complete coverage is effected by rippling through the odd numbered jets first and then rippling through the even numbered jets. The position of the small spots from the even numbered jets can be adjusted to maximize coverage and counteract offset between nozzle centers. Printheads with different size nozzles can also be operated by a staggered firing method using dual passes to offset spots in the scan direction by shifting the printhead between passes or alternating between groups of large and small nozzles. Further improvements to image quality can be realized by shifting the spots in the direction perpendicular to the scanning direction by tilting the printhead or offsetting the nozzles with respect to the ink channels on the printhead.

摘要翻译： 打印头使用大而小的墨滴喷射器来实现高效的灰度打印。 打印头布置成具有交替的大和小喷嘴的紧密堆积构造，其被定位成最大化覆盖范围，同时最小化喷射墨的体积。 打印头可以在单程模式或双通道模式下操作。 在单程模式中，完全覆盖通过首先通过奇数射流波纹，然后通过偶数喷射波纹来实现。 可以调整来自偶数喷嘴的小点的位置，以最大化覆盖范围并抵消喷嘴中心之间的偏移。 具有不同尺寸喷嘴的打印头也可以通过交错的点火方法来操作，使用双程通过在扫描方向上偏移打印头，使打印头在通过之间移动或在大喷嘴和小喷嘴组之间交替。 通过倾斜打印头或相对于打印头上的墨水通道偏移喷嘴，可以通过使垂直于扫描方向的方向上的点移动来实现对图像质量的进一步改进。

摘要： The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.
