摘要： A printhead IC is provided having an ejection nozzle having a heater for heating printing fluid, and drive circuitry for generating print pulses and maintenance pulses for driving the heater of the ejection nozzle. The maintenance pulses have a series of sub-ejection pulses preceding a de-clog pulse. The print signals are generated to heat the heater to form a first vapor bubble in printing fluid that causes ejection of the printing fluid from the nozzle. The de-clog pulse is generated to have lower power and longer duration than the print pulses so as to heat the heaters to form a second vapor bubble in the printing fluid which does not cause ejection. The sub-ejection pulses are generated to have lower power than the print pulses and shorter duration than the de-clog pulse so as to heat the heater without sufficient energy to nucleate a vapor bubble in the printing fluid.

摘要： An ink jet printhead includes a plurality of nozzles each having a nozzle aperture; a plurality of bubble forming chambers, each corresponding respectively to one of the plurality of nozzles; an inlet for communicating printing fluid between the nozzle aperture and a printing fluid supply, the inlet and the nozzle aperture being aligned along a common central axis; and a heater element disposed in each of the bubble forming chambers. Each heater element has two bubble nucleation regions suspended within the bubble forming chamber in a plane parallel to that of the nozzle aperture. The two bubble nucleation regions are laterally offset from the central axis, such that the lateral offset of one of the bubble nucleation regions is equal and opposite to the lateral offset of the other bubble nucleation region. The bubble nucleation regions are spaced from each other such that bubbles nucleated at each will grow until they unite to form the gas bubble that causes the ejection of a drop of ejectable liquid.

摘要： An inkjet printhead with a plurality of nozzles, a heater element adjacent each of the nozzles respectively for heating an ejectable liquid to form a gas bubble that causes the ejection of a drop of the ejectable liquid from the nozzle, and, a print engine controller for controlling the operation of the heater elements.

摘要： This invention provides for an inkjet printhead having an array of micro-electromechanical nozzles arrangements. Each nozzle arrangement includes side walls located on a wafer substrate with a roof layer deposited on said walls to define an ink chamber, with the roof layer defining a nozzle aperture. The nozzle arrangement also includes an inlet defined in the substrate to supply the ink chamber with printing fluid. Further includes is at least one heater element having a mass of less than 10 nanograms suspended between the side walls in the chamber, so that when electrical actuation energy of less than 500 nanojoules is applied to the heater element, a vapour bubble is formed in the fluid leading to a pressure increase in the chamber thereby ejecting the fluid via the nozzle aperture. The heater element has an annular shape with a point of collapse of the bubble near a centre thereof.

摘要： A unit cell is provided for an inkjet printhead. The unit cell includes a multilayered substrate defining an ink inlet passage. Walls extend from the substrate. A nozzle plate is supported by the walls to define a nozzle chamber in fluid communication with the ink inlet passage. The nozzle plate further includes a nozzle rim bounding an aperture in fluid communication with the nozzle chamber. Dual looped and elongate heater elements are suspended within the nozzle chamber which, when heated, cause ink in the nozzle chamber to be output through the aperture.

摘要： There is disclosed an ink jet printhead that has a plurality of nozzles unit cells 1 and one or more heater elements 10 corresponding to each nozzle 3. Each heater element 10 is configured to heat a bubble forming liquid 11 in the printhead to a temperature above its boiling point to form a gas bubble 12 therein. The generation of the bubble 12 causes the ejection of a drop 16 of an ejectable liquid (such as ink) through an ejection aperture 5 in each nozzle 3, to effect printing. The gas bubble encircles at least some of the heater element. By configuring the heater element such that the bubbles formed surround the element, the heat transfer to the bubble forming liquid is maximized. Less heat is wasted through conduction to the surrounding nozzle structures thereby raising the overall efficiency of the printhead.

Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through respective corresponding nozzle, to effect printing. Each heater element has a surface area to volume ratio greater than 4:1. This configuration ensures that heat is quickly transferred from the elements to the ink for efficient operation and minimal heating of the printhead substrate.

摘要： An inkjet printhead has nozzles and respective heater elements. A print engine controller actuates the heater elements to eject ink through the corresponding nozzle. During use, the print engine controller actuates each of the heater elements at least once every decap time. The decap time is a predetermined time period in which the viscosity of the ejectable liquid at the nozzle increases to a threshold, at which ejection fails and the nozzle clogs.
