Embodiment Construction

[0013] figure 1 An embodiment of a prior art method of mounting a transducer to a jet stack is shown. Nozzle stacks typically consist of stacks of plates or membranes that form fluidic channels that allow ink to flow from an ink reservoir to an array of nozzles or holes. Ink selectively emerges from the apertures to form a printed image on the print substrate. A nozzle stack may have multiple plates to form channels. Typically, one of the plates forms the body cavity or pressure chamber and is called the body plate. The diaphragm on which the transducer operates to cause flow into and out of the body cavity through a nozzle is usually mounted on the body plate. The transducer in turn is mounted on the diaphragm.

[0014] exist figure 1 In , the transducer plate consists of a piezoelectric material sandwiched between two conductive layers. Discussions herein may refer to the plate as a PZT plate, with the understanding that the plate may contain any transducer array that ...

Abstract

A method of mounting a printhead transducer to a diaphragm comprising: merging a transducer plate with the diaphragm; pressing the diaphragm to the plate to form an assembly; and after the diaphragm is pressed to the plate , cutting the plate to divide the plate into transducer arrays, wherein the transducer arrays are aligned with the body cavity array.

Description

technical field [0001] The present invention relates generally to the field of printheads, and more particularly to methods of mounting printhead transducers. Background technique [0002] Many types of inkjet printers use transducers to selectively expel ink from individual holes (also called nozzles or orifices) in an array of holes. The pattern formed on the printed substrate constitutes the printed image. The transducer is generally adjacent to the pressure chamber. Grouped signals typically cause the transducer to act on the membrane. A single signal causes the transducer to move the membrane away from the orifice, causing the pressure chamber to fill with ink. A second signal, usually of the opposite polarity to the first signal, causes the membrane to move in the other direction, allowing ink to exit the pressure chamber through the orifice. [0003] Typically, there is one transducer for each hole and pressure chamber, and the array of transducers is aligned with...
