The system includes a cooling system that compensates for nonuniform heating effects in a printhead which results in nonuniform temperatures. The distribution of the cooling system, and the effectiveness of the cooling system is set to maintain an approximately uniform ink temperature across the printhead.

摘要： A method of forming and moving ink drops across a gap between a print head and a print medium, or intermediate print medium, in a marking device includes generating an electric field, forming the ink drops adjacent the print head and controlling the electric field. The electric field is generated to extend across the gap. The ink drops are formed in an area adjacent the print head. The electric field is controlled such that an electrical attraction force exerted on the formed ink drops by the electric field is the greatest force acting on the ink drops. The marking device may be incorporated into a transfuse printing system having an intermediate print medium made of one or more materials that allow for lateral dissipation of electrical charge from the incident ink drops.

摘要： A method and mechanism for ensuring quality control in printed biological assays is provided. A multi-ejector system having a plurality of individual drop ejectors is loaded with a variety of biofluids. Biofluids include at least a carrier fluid, a biological material to be used in the testing, and markers, such as fluorescent dyes. Data regarding the biofluid loaded in each of the drop ejectors is stored along with an expected signature output of the biofluid. Particularly, the signature output represents signals from individual ones of the fluorescent markers included within the biofluid. Once a biological assay consisting of the biofluid drops has been printed, a scanner capable of detecting the markers scans the biological assay and obtains signature output signals for each of the drops of the biological assay. A comparing operation is undertaken to compare the obtained signature output through the scanning operation, with the expected signature output signals for the biofluid loaded in the corresponding drop ejector. The biological material itself may also be tagged with a marker to ensure its inclusion in the biofluid. By the comparing operation, it is possible to verify the biofluids were loaded in the proper drop ejector, including the proper biological material, and that the drop ejectors are functioning properly.

摘要： Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more. A printhead implementation includes an array of such microstructures supported between drive side and drop side assemblies.

摘要： A number of architectures of switch compensation networks are described for the provision of a compensation current which ensures the maintaining of a desired switching ratio in an acoustic printhead. The described architectures include those which provide column compensation, row compensation, and row and column compensation to a transducer switching matrix. Control of the switching ratio by the compensation networks, is used in consideration of the dissipation of heat energy through expulsion of a heated drop, to provide a precisely controlled balance.

摘要： In AIP printheads, misfunction after printing a number of prints, due to the accumulation of ink and dust around orifices in the orifice plate may occur. In order to clean the printheads, the dirty printhead is first capped and the ink pressure in the printhead increase significantly to allow ink to escape through the orifices and completely fill a small gap inside the cap portion. After letting the orifices soak for a predetermined time to dissolve the dried ink and loosen dust debris which may be found on the printheads, the cap drainhole is opened to drain the ink while keeping the ink pressure inside the head at an intermediate higher level. This higher pressure prevents the ink still remaining inside the bore of each orifice hole from reentering the printhead. The dirty ink remaining inside the orifice bore is removed using a wiping station in separate steps.
摘要翻译：在AIP打印头中，由于孔板上的墨孔周围的墨水和灰尘的积聚可能会在打印多张打印后发生故障。为了清洁打印头，首先盖住脏的打印头，并且打印头中的墨水压力显着增加，以使油墨通过孔口逸出并完全填充盖部分内部的小间隙。在使孔口浸泡预定时间以溶解干燥的油墨并松开打印头上可能发现的灰尘碎屑之后，打开帽排水孔以排出油墨，同时将头部内的油墨压力保持在较高水平。这种较高的压力可防止仍然残留在每个孔口孔内的墨水重新进入打印头。在单独的步骤中，使用擦拭站去除留在孔口内的脏墨。
