REMOVABLE ORIFICE PLATE FOR INK JET PRINTHEAD AND SECURING APPARATUS The present invention provides a removable orifice plate securing structure for use in conjunction with a conventional ink jet printer printhead assembly. The orifice plate securing structure comprises an orifice plate mounting member having a rear end portion disposed in an opposing relationship with the front end surface of the printhead body portion, a front side surface and an opening extending outwardly from the rear end portion to the front side surface. The orifice plate mounting member is configured to removable secure the orifice plate between the front side surface of the orifice plate mounting member and the front end surface of the printhead body portion in an operative alignment position with the ink receiving chambers. The opening is configured to allow ink from the ink discharge orifices to operatively pass outwardly from the orifice plate mounting member. The orifice plate securing structure also comprises a securing means for removable securing the orifice plate mounting member and the orifice plate to the printhead body portion in an operative alignment position with the ink receiving chambers.
PLAQUE A ORIFICE AMOVIBLE AVEC DISPOSITIF DE FIXATION POUR TETE D'IMPRESSION A JET D'ENCRE - La présente invention a pour objet une structure de fixation pour plaque à orifice amovible destinée à un ensemble de tête d'impression à jet d'encre. La structure de fixation pour plaque à orifice comporte un élément de fixation pour plaque à orifice possédant une surface arrière en opposition avec la surface de la partie avant du corps de la tête d'impression, une surface avant et un orifice ouvert vers l'extérieur depuis l'arrière vers la surface de la partie avant. L'élément de montage de la plaque à orifice est configuré pour permettre la fixation de la plaque à orifice amovible entre la surface de la partie avant de l'élément de fixation de la plaque à orifice et la surface de l'extrémité avant du corps de la tête d'impression, de sorte que l'orifice coïncide avec l'axe des réservoirs d'encre. L'orifice est configuré pour permettre à l'encre projetée par les orifices de projection de traverser l'orifice de l'élément de fixation de la plaque à orifice. La structure de fixation de la plaque à orifice comporte en outre un organe de fixation permettant de fixer provisoirement l'élément de montage de la plaque à orifice ainsi que la plaque à orifice au corps de la tête d'impression en alignement axial avec les réservoirs d'encre.
