摘要： A drop-on-demand ink jet has an ink chamber coupled to a source of ink, and an ink drop orifice with an outlet. An acoustic driver produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop orifice and outlet. The driver is driven with bipolar drive pulses having a refill pulse component and an eject pulse component of a polarity which is opposite to the refull pulse component. The refill and eject pulse components are separated by a wait period. The drive pulses may be adjusted to minimize their energy content at a frequency corresponding to the dominant acoustic resonance frequency of the ink jet. This will accelerate drop breakoff, optimize drop shape and minimize drop speed variations over the range of drop printing rates. The ink jet printer of the present invention may be used to print with a wide variety of inks, including phase change inks to achieve high print quality at high print rates.

摘要： A drop-on-demand ink jet has an ink chamber coupled to a source of ink, and an ink drop orifice with an outlet. An acoustic driver produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop orifice and outlet. The size of the ink drops may be varied, such as by driving the acoustic driver with varying drive signals, preferably comprising individual or combinations of plural bipolar drive pulses. The ink jet printer of the present invention may be used to print with a wide variety of inks, including phase change inks.

摘要： A drop-on-demand ink jet print head (9) has an ink pressure chamber (22) coupled to a source of ink (11) and an ink drop ejecting orifice (103) with an ink drop ejection orifice outlet (14). An acoustic driver (36), in response to a driver signal (100), produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop ejecting orifice (103) and the ink jet ejection orifice outlet (14) of the ink jet print head (9). In accordance with the present invention, controlling the operation of the ink jet print head (9) with a particular drive signal reduces print quality degradation resulting from rectified diffusion, which is the growth of air bubbles dissolved in the ink from the repeated application of pressure pulses to the ink residing within the ink pressure chamber (22) of the ink jet print head (9), such pressure pulses causing the application of pressures below ambient pressure. This method of controlling the operation of the ink jet print head (9) applies pressure below ambient pressure to the ink residing within the ink pressure chamber (22) of the ink jet print head (9) at magnitudes less than the threshold pressure magnitude that leads to the air bubble growth.

摘要： A first surface of a first metal component of an ink jet print head is bonded to a second surface of a second metal component of the ink jet print head, the first and second surfaces being of materials having the same or similar coefficients of thermal expansion. A layer of filler material is electroplated or otherwise placed on at least one of these surfaces. The filler material has a melting point which is below the melting point of the first and second components, and the total thickness of the filler material on the surfaces together is in the range of from approximately one-sixteenth micron to approximately five microns, with one-eighth micron to two microns being a preferred range. These surfaces are placed together and subjected to heat and pressure to diffusion bond the surfaces without melting the filler material. The diffusion bonding is performed in one approach until no more than approximately one micron of filler material remains between the surfaces. Thereafter, the filler material is melted without melting the first and second components to thereby braze the first and second components together.

摘要： Provided is a priming mechanism for priming a biofluid drop ejection device having a drop ejection opening leading to an ejection reservoir. The priming mechanism includes a vacuum unit which generates a vacuum force, connected to a vacuum nozzle. The vacuum nozzle is located over the drop ejection opening. A disposable sleeve or tubing is attached to the vacuum nozzle and is placed in operational contact with the drop ejection opening. A fluid height detection sensor is positioned to sense a fluid height within at least one of the disposable tubing and the vacuum nozzle. Upon sensing a predetermined fluid height, by the fluid height detection sensor, the priming operation is completed, and the primer mechanism is removed from the operational contact with the drop ejection opening.

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 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。
