Patent

CA 2506725

There is disclosed an ink jet printhead which comprises a plurality of nozzles and one or more heater elements (10) corresponding to each nozzle. Each heater element (10) 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 the respective corresponding nozzle (3), to effect printing. Each heater element includes solid material and is configured so that, when heated, a mass of less than 10 nanograms of that solid material is heated for heating the bubble forming liquid.

L'invention concerne une tête d'impression à jet d'encre comprenant une pluralité de buses et un ou plusieurs éléments (10) de chauffe correspondant à chaque buse. Chaque élément (10) de chauffe est conçu pour chauffer un liquide producteur de bulles dans la tête d'impression, à une température supérieure à son point d'ébullition de manière à former une bulle de gaz dans celle-ci. La production de la bulle entraîne l'éjection d'une goutte de liquide éjectable (p. ex. d'encre) à travers la buse (3) correspondante, réalisant ainsi l'impression. Chaque élément de chauffe comprend un matériau solide configuré de manière qu'une fois chauffé, la masse de matériau solide chauffée pour permettre le chauffage du liquide producteur de bulles est inférieure à 10 nanogrammes.
