摘要： A method is provided for improving the operation of ink jet components. The components are machined using known, conventional machining techniques. All of the machined surfaces are then treated using non-abrasive, intrinsically leveling polishing processes to eliminate particulate sources. The conventional machining may be any known technique, such as electro discharge machining. The polishing processes include, but are not limited to, electrochemical means such as electropolishing, electrochemical deburring, and electrochemical grinding. The polishing processes may further comprise vapor polishing, and laser treatment to reflow the machined surface.

摘要： An ink jet printing device has a drop generator for producing continuous streams of ink drops from at least one orifice and further has stimulation control electronics for maintaining desired stimulation conditions in response to a feedback from the drop generator. First and second feedback transducers measure the stimulation amplitude in the drop generator and generate feedback output signals in response to the stimulation. The feedback output signals are approximately equal in magnitude and opposite in sign to each other when the stimulation amplitude in the drop generator is a desired stimulation mode. An amplifier, whose inputs are the feedback output signals, provides an amplifier output signal to the stimulation control electronics which is the difference between the two feedback output signals.

摘要： A differential circuit (26) is used to compare the current to the drive transducers to a matched reference circuit (18). With the capacitive current from the piezoelectric transducer (14) canceled out in this manner, the resulting output current (44) provides a direct measure of the vibration amplitude of the drop generator. By adding an appropriate inductor (48) in parallel to the capacitive piezoelectric drive transducers, the loading of the drive electronics, or oscillator, is significantly reduced.

摘要： A drop generator for use in an ink jet printer is capable of stimulating long ink jet arrays at high operating frequencies. The drop generator comprises a substantially uniform cross section for a central portion and two end sections with different cross sections. The end sections have features to adjust a resonant frequency of the end sections to match that of the central portion. In particular, these features comprise cuts on a top of the drop generator. The drop generator utilizes multi-lobed radial bending modes for vibration of an array of orifices, and the vibrational modes are driven by at least two rows of transducers which extend substantially the length of the drop generator. The transducers are placed consistent with a lobe structure of an operational radial bending mode.

摘要： A system and method are provided for improving the operating latitude for the charging and deflection voltage of an ink jet printhead, by catching non-print drops (16) with a wall impinging catcher to form a fluid layer in a face (10) of the catcher; and lowering drag on the fluid layer on the catcher face. This is accomplished by providing a drop generator for producing ink drops and a catcher/charge plate assembly for catching and recirculating non print drops. A printhead frame maintains the alignment of the drop generator and the catcher/charge plate assembly. Temperature induced distortion of these components is eliminated by heating them to a constant temperature.
