ABSTRACT:
The present invention is directed to an orifice plate for use with an ink jet printhead assembly and a method for fabricating that orifice plate and a printhead assembly incorporating the orifice plate and a method for fabricating that printhead. The orifice plate has either a projection extending outwardly from a rear side surface of the orifice plate that is configured to be closely received by a corresponding alignment cavity in the front end body portion of the printhead or an alignment cavity formed in the rear side surface of the orifice plate that is configured to closely receive a projection extending outwardly from the front end portion of the printhead body. An ultraviolet light curable adhesive may be used to adhesively intersecure and seal the orifice plate on the printhead body.
