摘要： An ink jet printhead body has an ink filter structure (56,84) integrally incorporated therein and operative to filter ink flowing into its internal ink receiving channels (40) disposed between piezoelectrically deflectable interior wall portions of the body. In various illustrated embodiments of the printhead, the filter structure (56,84) is defined by a series of photoetched micro filter passageways (58,86) formed integrally in an outer side portion of the printhead body, a filter cavity formed in the outer side portion and receiving a separate photoetchable filter member in which photoetched micro filter passageways (58,86) are formed, and a filter cavity (80) formed in the outer side portion and receiving a separate mesh-type micro filter member. In an embodiment of the printhead (10) adapted for use with phase change type ink, a heating channel (88) is interiorly disposed within the outer body side portion and operatively receives an electrical resistance heating wire (96) used to heat phase change type ink disposed within the ink receiving channels (40) in the printhead body.

摘要： Method for manufacturing a sidewall actuatable, high density channel array for an ink jet printhead (10). A first surface of a main body portion (12) formed from an inactive material is conductively bonded to a first surface of a first intermediate body portion (14) formed from an active material. A plurality of parallel grooves are then machined through the first intermediate body portion (14) and part of the main body portion (12) to form a plurality of channels (18) separated by a corresponding plurality of sidewall actuators comprised of a first sidewall section formed from an inactive material and a second sidewall section formed from an active material. A top body portion (16) is then conductively mounted to the intermediate body portion.

摘要： A sidewall actuated channel array for a high density ink jet printhead. The sidewall actuator (28) includes a top wall (16), a bottom wall (12) and at least one elongated liquid confining channel (18) defined by the top wall (16), the bottom wall (12) and sidewalls (30,32). The actuator sidewall is comprised of a first actuator sidewall section (32) formed of a piezoelectric material poled in a first direction perpendicular to a first channel (18) and attached to the top wall (16), a second actuator sidewall section (30) attached to the first sidewall section (32) and the bottom wall (12), and means for applying an electric field across the first actuator sidewall section (32) and perpendicular to the direction of polarization. When the electric field is applied across the first sidewall section (32), the actuator sidewall engages in a motion which produces an ink ejecting pressure pulse in the channel (18).

摘要： Method of manufacturing a sidewall actuator array for an ink jet printhead in which a series of longitudinally extending, generally parallel grooves are formed in a body portion of the ink jet printhead. In various embodiments thereof, the body portion may be comprised of a lower body portion formed of an inactive material and an intermediate body portion formed of an active material, a lower body portion formed of active material poled in a first direction and an intermediate body portion formed of active material poled in a second, opposite direction, a lower body portion formed of active material poled in a first direction, a insulative spacing portion and an intermediate body portion formed of active material poled in a second, opposite direction, or a single body portion formed of an active material. After forming grooves therein, a layer of conductive material is deposited on inner side surfaces exposed during the grooving step. If the ink jet printhead is comprised of a single active body portion, the grooves formed in the lower body portion are then deepened to expose second interior side surfaces of the lower body portion. A bottom side surface of an inactive upper body portion is then mounted to the top side surface of the active intermediate body portion to form the sidewall actuator array.
