A method and structure for an ink jet print head which includes the use of two or more flexible circuits and a piezoelectric element array. A first pad array is included on a first flex circuit to power a first portion of the piezoelectric element array of the print head, and a second pad array is included on a second flex circuit to power a second portion of the piezoelectric element array of the print head. Using two flex circuits requires only half as many traces to be formed on each flex circuit, which can relax spacing requirements and design tolerances.

High density electrical interconnect using limited density flex circuits

A printhead has an aperture plate on a front side of the printhead, a diaphragm plate on a back side of the printhead, a body intermediate the aperture plate and the diaphragm plate, a chamber disposed within the body, a port boundary defining a port area, the port boundary disposed on the diaphragm plate and adjacent the chamber, a peripheral partially-etched region coinciding with a first portion of the port boundary, and a peripheral non-etched region coinciding with a second portion of the port boundary, wherein the port boundary is fractured at the partially etched peripheral portion and bent at the non-etched peripheral portion, the non-etched peripheral portion structured to prevent separation of the diaphragm plate and a leaflet defined by the partial-etched portion.

Diaphragm plate with partially-etched port

A printing system includes a print head to deliver ink to an image receptor and at least one ink reservoir to deliver ink to the print head. Driving circuitry provides signals to the print head to control delivery of the ink and a flexible circuit interposed between the print head and the ink reservoirs connects the driving circuitry to the print head. The flexible circuit may include a heater to provide heat to the ink reservoirs. Alternatively, the flexible circuit may be replaced with a rigid substrate having a heater within its layers.

Circuitry for printer

A printhead assembly that includes a partially-etched port structured to be opened by application of pressure to the port area, one or more leaflets being depressed into an internal chamber communicating with the open port.
