Abstract

L'invention concerne un éjecteur de gouttes de liquide comprenant une pluralité de têtes à jet d'encre (100) présentant chacune une membrane, un actionneur destiné à déplacer la membrane et une buse d'éjection du liquide dans une cavité augmentant/diminuant par déplacement de la membrane sous la forme d'une goutte de liquide, un circuit de commande de l'actionneur, un moyen (182) de sélection d'une buse éjectant une goutte de liquide dans la pluralité de têtes à jet d'encre (100), un moyen (10) de détection d'une oscillation résiduelle de la membrane et de détection d'une éjection anormale d'une goutte de liquide sur la base du type d'oscillation de l'oscillation résiduelle détectée, et un moyen (23) destiné à commuter la connexion avec l'actionneur du circuit de commande au moyen (10) détectant l'éjection anormale, après qu'une goutte de liquide ait été éjectée par commande de l'actionneur.
