Patent

CA 2506721

There is disclosed an ink jet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle (3). 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 (12) therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is substantially covered by a conformal protective coating (77) which has been applied to all sides of the heater element (10) simultaneously so that the coating is seamless.

Cette invention concerne une tête d'impression à jet d'encre comportant une pluralité de buses (3) ainsi qu'un ou plusieurs éléments chauffants (10) associés à chacune des buses (3). Chacun des éléments chauffants est conçu pour chauffer un liquide formant des bulles dans la tête d'impression jusqu'à ce qu'il atteigne une température supérieure à son point d'ébullition de façon qu'une bulle de gaz (12) soit formée dans le liquide. La génération de cette bulle entraîne l'éjection d'une goutte d'un liquide éjectable (tel que l'encre) par la buse correspondante, ce qui permet de produire l'impression. Chacun des éléments chauffants est sensiblement recouvert d'un revêtement (77) de protection conforme qui a été appliqué simultanément sur tous les côtés de l'élément chauffant (10) de façon que le revêtement soit uniforme.
