    摘要： An emitter device including a focusing array with plural focusing columns to focus emissions from one or more emitters onto a target medium. Relative movement between the target medium and the focused emissions allows each focusing column to focus emissions over an area of the target medium encompassing the movement range. In a preferred embodiment, separate emitter, focusing array and target medium substrates are used. The focusing array may be moveable, or in a particularly preferred embodiment, is affixed to the emitter substrate, in which case the target medium substrate is movable or the focusing array includes beam direction control.

    摘要： A fluid ejection assembly includes a fluid slot, and a group of uniformly spaced drop generators, where each drop generator is individually coupled to the fluid slot through a first end of a drop generator channel and to a connection channel at a second end of the drop generator channel. The fluid ejection assembly includes a pump disposed within a pump channel located between two drop generator channels, and is configured to circulate fluid from the fluid slot, into the connection channel through the pump channel, and back to the fluid slot through the drop generator channels.

    摘要： In an embodiment, a method of degassing ink in a fluid ejection device includes generating a localized nucleation site within an ejection chamber of a fluid ejection device. An air bubble is formed at the nucleation site, and the air bubble is prevented from venting into an ink supply slot using a bubble-impeding structure. The air bubble is vented through a nozzle associated with the ejection chamber and into the atmosphere.

    摘要： One aspect is a drop detection arrangement including a light source for projecting a light beam for scattering light off of an ejected drop. The arrangement includes a light collector configured to collect the scattered light off the ejected drop and configured to process scattered light into an output signal. The arrangement includes a controller configured to receive the output signal from the light collector, to calculate the velocity of the ejected drop and to determine the volume of the ejected drop using the output signal and the velocity of the ejected drop.

    摘要： A method of monitoring nozzle condition in an array of inkjet nozzles comprises ejecting at least one black ink drop from an inkjet nozzle, wherein the black ink comprises a black colorant and a colloidal metal or metal-containing dopant. Light from a collimated light source is directed onto an ink drop-in-flight, and light-scatter from the drop is detected. The dopant increases light-scatter by the ink drop of an incident collimated light beam relative to the same ink without the dopant. From the detected light-scatter, an operational condition of the inkjet nozzle is determined. The dopant is visually undetectable in a printed mark made by the black ink, and the ink has a printed black optical density which is substantially the same as that of the same ink without the dopant.

    摘要翻译： 在喷墨喷嘴阵列中监测喷嘴状态的方法包括从喷墨喷嘴喷射至少一个黑色墨滴，其中黑色墨水包括黑色着色剂和胶体金属或含金属的掺杂剂。 来自准直光源的光被引导到飞行中的墨滴，并且检测到来自液滴的光散射。 掺杂剂通过入射准直光束的墨滴相对于没有掺杂剂的相同墨水而增加光散射。 从检测到的光散射确定喷墨喷嘴的操作状态。 在由黑色墨水制成的印刷标记中，目前看不到该掺杂剂，并且墨水具有与没有掺杂剂的相同墨水基本上相同的印刷黑色光密度。
