Abstract:
A method of manufacturing a print head for use with an ink jet printer, the print head having a plurality of parallel ink pressure chambers each of which is defined by adjacent walls, and having a cover bonded on top surfaces of the walls, comprising:forming a plurality of parallel grooves in a surface of a piezoelectric element, and a plurality of parallel walls aligned in a row, each of said grooves being bounded by adjacent ones of the parallel walls;applying an adhesive either to said top surfaces of the plurality of walls or to a surface of a cover by screen printing, said adhesive being applied by moving a squeegee in a direction essentially only perpendicular to directions in which the walls extend; andplacing said cover on said top surfaces of the walls so as to close said grooves to form the ink pressure chambers.
