Abstract: The present teachings describe a printhead assembly. The printhead assembly includes a first plate and a second plate stacked together. The printhead assembly includes a first adhesive between the first plate and the second plate for bonding the plates together. The printhead assembly includes a second adhesive surrounding an outer edge of the first adhesive wherein the second adhesive has an oxygen migration rate lower than an oxygen migration rate of the first adhesive. An oxygen sensitive component is contained within the outer edge of the first adhesive.

Abstract: A method for operating an inkjet printer includes identifying a pattern of ink drops ejected from an inkjet with reference to image data for a printed image, identifying a waveform component for an electrical signal operating the inkjet to eject an ink drop in the pattern of ink drops with reference to at least a portion of the image data, and generating the electrical signal with the identified waveform component to eject the ink drop in the pattern of ink drops at a first velocity onto a first location of an image receiving surface.

Abstract: A method of printing executes a software instruction using a print system controller to measure a vertical position of each row of an array of jets, having at least one offset subset of the array offset in a movement direction, adjusts timing of firing intervals for the offset subset such that the offset subset fire after a longer interval than other jets, and fires jets other than the offset subset at a predetermined firing interval. A print head has an array of transducers, an ink chamber to store ink arranged adjacent the array of transducers, and an array of jets arranged adjacent the ink chamber such that when selected ones of the array of transducers are activated, ink from the chamber exits a jet corresponding to the selected ones of the transducers, the array of jets having at least one subset of the array offset in a vertical direction relative to the other jets.

Abstract: A drop generator includes a pressure chamber and a flexible diaphragm plate disposed on the chamber and forming a wall of the pressure chamber. A piezoelectric transducer having a bottom surface is attached to the diaphragm plate. The diaphragm plate includes a recess that forms a perimeter around the bottom surface of the transducer that partially underlies at least one edge of the bottom surface. An inlet channel is connected to the pressure chamber and configured to direct ink to the pressure chamber from a manifold. An outlet channel is connected to the pressure chamber to receive ink from the pressure chamber and has a channel axis that is perpendicular to the diaphragm plate. The outlet channel includes a first outlet channel section and a second outlet channel section. The first outlet channel section includes a plurality of subsections having alternating diameters. The second outlet channel section includes an aperture disposed at an end thereof.
