Abstract
A method of manufacturing a print head is for use with an ink Jet printer. The print head includes a plurality of parallel ink pressure chambers defined by a plurality of walls and a cover bonded on the top surfaces of the walls. The method includes the steps of forming a plurality of parallel grooves in a piezoelectric element, the grooves being bounded by a plurality of parallel walls aligned in a row; and applying an adhesive either to the top surfaces of the walls or to a surface of a cover in registration with top surfaces of the walls, the adhesive being applied by screen printing, the adhesive being applied by moving a squeegee in a direction perpendicular to a direction in which the grooves extend.
