摘要

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.
