摘要： A thermal inkjet printhead with generally planar heater elements disposed in respective bubble forming chambers such that they are bonded on one side to the chamber so that the other side faces into the chamber. Each heater element receives an energizing pulse to heat ejectable liquid above its boiling point to form a gas bubble on the side facing into the chamber, whereby the gas bubble causes the ejection of a drop of the ejectable liquid from the nozzle. The chamber has a dielectric layer proximate the side of the heater element bonded to the chamber. The dielectric layer has a thermal product less than 1495 Jm−2K−1s−1/2, the thermal product being (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer. The present invention reduces the drop ejection energy and the heat dissipation into the printhead IC by improving the thermal isolation between the heater and the substrate.

摘要： Provided is a pagewidth printhead with a controller, the printhead having a plurality of micro-electromechanical nozzle arrangements. Each nozzle arrangement includes a multilayered substrate defining an ink inlet passage and walls extending from the substrate. Also included is a nozzle plate supported by the walls to define a nozzle chamber in fluid communication with the ink inlet passage, the nozzle plate having a nozzle rim defining an ejection port in fluid communication with the nozzle chamber. Each arrangement also includes a plurality of heater elements suspended between the walls in the chamber, so that when electrical actuation energy is applied to respective heater elements a vapour bubble is formed in the fluid leading to a pressure increase in the chamber thereby ejecting the fluid via the ejection port. The controller is configured to individually actuate respective heater elements to facilitate weighted ink drop volumes to be ejected from the nozzle arrangement.

摘要： An inkjet printhead having a high density array of micro-electromechanical nozzles arrangements. Each arrangement comprises side walls located on a wafer substrate with a roof layer deposited on said walls to define an ink chamber, the roof layer defining a nozzle aperture; an inlet defined in the substrate to supply the ink chamber with printing fluid; and at least one heater element having a mass of less than 250 picograms suspended between the side walls in the chamber, the heater element operable to form a vapour bubble when electrical actuation energy of less than 120 nanojoules is applied thereto, said heater element having an annular shape with a point of collapse of the bubble near a centre thereof. The inlet, heater element and nozzle aperture are configured such that all heat generated in the ink chamber by the heater element per actuation is negated completely between actuations by an intake of unheated ink into the ink chamber through the inlet and an expulsion of heated ink from the ink chamber through the nozzle aperture.

摘要： A thermal inkjet printhead with heater elements formed from a self passivating transition metal nitride, but it oxidizes readily. By introducing an additive that allows the metal nitride to self passivate, the heater element forms a surface oxide layer, where the oxide has a low diffusion coefficient for oxygen so as to provide a barrier to further oxidation. With enhanced oxidation resistance, coatings to protect the heater from oxidative failure become unnecessary and the energy needed to form a bubble is reduced.

摘要： A thermal inkjet printhead with heater elements disposed in respective bubble forming chambers whereby each heater element is configured for receiving an energizing pulse to form a gas bubble in an ejectable liquid that causes the ejection of a drop of the ejectable liquid from the nozzle. The energizing pulse has duration less than 1.5 micro-seconds (μs) and the nozzles are “self cooling”, in the sense that in the sense that the only heat removal required by the chip is the heat removed by ejected droplets. The printhead is designed for operation with reduced pulse duration, so the amount of heat that diffuses into the liquid and the substrate prior to nucleation of the vapor bubble is reduced. This facilitates self cooling operation.
