providing a print head body portion formed from
a piezoelectric material and having a front end
surface, and a spaced interior series of parallel
ink receiving chambers opening outwardly through
said front end surface;
providing an orifice plate having a rear side
surface;
forming spaced apart adhesive receiving openings
in said orifice plate and said front end surface of
said body portion;
applying a layer of adhesive material between
said front end surface of said body portion and said
rear side surface of said orifice plate;
forcing said orifice plate and said body portion
toward one another in a manner reducing the
thickness of said layer of adhesive material and
causing portions of said layer of adhesive material
to flow into said adhesive openings in both said
orifice plate and said body portion, to thereby
strengthen the adhesive bond between said orifice
plate and body portion by increasing the total
contact area between said adhesive material and said
orifice plate and body portion; and
permitting the adhesive material to harden.
