摘要： A method and apparatus are disclosed for providing feedback control of the ink drop velocity in a drop marking system. The control system maintains essentially constant velocity of the ink drops as they pass through a deflection field which causes certain of the electrically conductive drops to be directed onto a substrate to be marked. The ink flow between two selected points is monitored by a control device to generate ink flow rate data and compared against a reference value. In the event that a flow rate deviation is sensed, appropriate action is taken to change the flow rate. Such action includes altering ink viscosity and/or ink pressure.

摘要： A clean-in-place system for use in an ink jet printhead has a compartment and an end plate with a slot therein to permit ink drops to be projected from the compartment onto a substrate to be marked. For cleaning purposes, a shutter is disposed adjacent the slot to seal it. Thereafter, the pump floods the compartment with ink solvent from a solvent reservoir. The solvent may be agitated by air or a mechanical device. Thereafter, a drain line is used to remove the solvent from the compartment. The pneumatic shutter is reopened after the solvent is withdrawn to enhance the drying of the components. The shutter may consist of an inflatable member and a pump for supplying compressed air to the inflatable member to inflate and deflate it.

摘要： According to certain aspects of an embodiment of the present invention, a deflection electrode assembly is provided for use in a continuous ink jet printer of the type which projects a stream of ink drops toward a substrate and controls placement of the ink drops on the substrate by selectively charging the individual ink drops and passing the charged ink drops through an electric (deflection) field created by the deflection electrode assembly. The deflection electrode assembly includes a high voltage deflection electrode and a low voltage deflection electrode positioned on opposite sides of the ink drop stream. A dielectric insulating member is mounted on at least one of the deflection electrodes. The insulating member include a longitudinal opening which exposes the deflection electrode along the path of the ink jet stream, thereby virtually eliminating the tendency for accumulated ink to decrease the strength of the deflection field. The insulating member extends inwardly and underlies the bottom face of the deflection electrode along at least its front and side edges. Providing insulation along the front and side edges of the deflection electrode reduces arcing between the deflection electrodes. Providing the longitudinal opening in the insulating member reduces the field distortion effects of micro-satellite ink drops that would otherwise accumulate on the insulating member.
摘要翻译： 根据本发明的实施例的某些方面，提供了一种用于连续喷墨打印机的连续喷墨打印机，该打印机将墨滴流朝向基底投影，并通过以下方式控制墨滴在基片上的放置： 选择性地对各个墨滴进行充电，并使带电的墨滴通过由偏转电极组件产生的电（偏转）场。 偏转电极组件包括位于墨滴流的相对侧上的高电压偏转电极和低电压偏转电极。 电介质绝缘构件安装在至少一个偏转电极上。 绝缘构件包括沿着喷墨流的路径使偏转电极露出的纵向开口，从而实际上消除了累积墨水降低偏转场强度的倾向。 绝缘构件沿着至少其前侧和侧边缘向内延伸并且在偏转电极的底面下方延伸。 沿着偏转电极的前边缘和侧边缘提供绝缘，减少了偏转电极之间的电弧。 在绝缘构件中提供纵向开口减小了否则会积聚在绝缘构件上的微卫星墨滴的场失真效应。

摘要： A variable orientation ink catcher for use with ink jet printing equipment receives unused ink drops. The drops are returned to the printing system for reuse. The catcher includes an arcuate receiving portion offset from an outlet port. Caught ink flows by gravity from the receiving portion via a reservoir to the outlet port through a wide range of angular orientations.

摘要： A valve is disclosed suitable for use in ink marking systems. The valve has an output port, a supply port, and a control port. The control port communicates with a chamber disposed above a flexible diaphragm while the output port communicates with a reservoir to be periodically supplied with fluid. The diaphragm flexes between an open position permitting the supply port to communicate with the output port and a closed position blocking such communication as a function of the pressure differential across the diaphragm created by pressure changes at the central port.

摘要： A fast acting ink valve adapted to be used in conjunction with the nozzle of an ink jet printing system is disclosed. A flexible diaphragm modulates flow through a valve chamber. A spring biases the diaphragm to a sealed position to prevent flow. Ink pressure in the marking system unseals the diaphragm permitting flow. Unlike check valves, the invention has minimal pressure drop due to the location of the bias spring outside the ink flow path.

摘要： Flight time of a stream of ink drops is measured and compared against a set point to determine variations therefrom. Variations due to changes in the ink composition are compensated for by adding or withholding solvent in proportion to the detected change. Changes due to variations in nozzle drive voltage result in the computation and use of a new flight time set point value, if necessary to avoid erroneous corrective action.

摘要： A drop deflection device suitable for use in a drop marking system employs an electret. Electrically conductive marking drops such as inks are given an electrical charge. The drops pass between a pair of deflections plates at least one of which is formed by an electret (a dielectric material which has been subjected to corona discharge to create a relatively permanent electrically charged material body). Depending upon the presence or absence of a charge on a particular drop, it will be deflected by the field between the plates on to a substrate for marking. If uncharged, the drops continue to a collection device which returns them to the ink reservoir.
