Abstract: A high density ink jet printhead (10) is fabricated by first forming a body subassembly (12) comprising a piezoelectric main block (13) having metallic layers (22, 24) disposed on opposite first and second sides (14, 16) thereof, and piezoelectric sheets (26, 28) secured to front portions of the metallic layers. Using a precision dicing saw, a first spaced series of parallel grooves, longitudinally extending between the front and rear ends of the subassembly, are cut into the first side of the subassembly. The subassembly is then placed, groove side down, in a support fixture having mirrors secured thereto and positioned adjacent the opposite ends of the grooves. Reflections of opposite groove ends in the mirrors are then used as line-of-sight guides to position the saw which is then used to form a second series of grooves in the second subassembly side which are in precise lateral alignment with the first series of grooves. Covering blocks (34, 36) are then secured to the opposite piezoelectric sheets (26, 28) over the open outer sides of the grooves and form therewith interior ink receiving channels bounded along their lengths by piezoelectrically deflectable side wall segments of the printhead body. The rear ends of the channels are sealed off, ink supply conduits (64) are communicated with rear end portions of the channels, and a plate member (58) having first and second spaced series of ink discharge orifices (60, 62) respectively communicated with the front ends of the first and second series of interior channels is secured over the front end of the printhead body.

The cover plate (42) is mounted to the main body portion (34) such that the first opening (50) is in communication with the first ink carrying channel (50a, 50c) and the second opening (52) is in communication with the second ink carrying channel (50b, 50d).

Volume modulatable droplets of ink may be ejected from the ink jet printhead (32) by simultaneously applying a voltage pulse having a selected magnitude to the first ink carrying channel and a voltage pulse having a magnitude ranging between zero and the selected magnitude to the second ink carrying channel. Alternately, volume modulatable droplets of ink may be ejected from the ink jet printhead by sequentially applying a voltage pulse having a selected time duration to the first ink carrying channel and a voltage pulse having a time duration ranging between zero and the selected time duration to the second ink carrying channel.

Abstract: Method of forming an orifice array for an ink jet printhead (29). Excimer laser radiation is used to ablate an orifice array in a cover plate (10) having a removable backing (16), a front side layer (12) formed from either an ablatable inactive material such as polyimide, a non-wettable material doped to absorb excimer radiation, or an ablatable inactive material such as polyimide with a very thin surface layer of a non-wettable material, and an intermediate layer (14) formed from an adhesive material. First, a series of generally square indentations (26) approximately 80 mu m on each side and which extends through the removable backing (16) and the intermediate layer (14) and partially through the front side layer (12) exposing an interior surface (27) of the front side is formed at spaced locations along the back side surface of the cover plate (10). Next, a corresponding series of generally circular apertures (28) approximately 40 mu m in diameter, each positioned in the general center of the corresponding indentation (26) and extending through the front side layer (12) is formed in the cover plate (10).

Abstract: A length mode drop on demand type ink jet print head includes a lower body portion formed of an active piezoelectric material and an upper body formed from an inactive material. The lower body portion, which includes a plurality of longitudinally extending projections, is poled in a first direction generally orthogonal to both its longitudinal and vertical axes. The upper body portion also includes a plurality of longitudinally extending projections. The lower and upper body portions are mated such that the lower and upper body projections are spaced interdigitally with each other. By mating the lower and upper body portions in this manner, a plurality of ink-carrying channels are formed. The ink jet print head further includes a controller for selectively applying an electric field across each of the lower body projections in the poling direction. When an electric field is applied across one of the lower body projections in this fashion, the projection imparts a pressure pulse to the ink-carrying channel associated therewith. The active lower body portion may be replaced with an inactive lower body portion, an active intermediate body portion which includes a plurality of longitudinally extending projections, each having a strip of conductive material along the top surface thereof, and a layer of conductive material mounting the lower and intermediate body portions together. Here, the intermediate body portion would be poled in its vertical axis and the electric field would be applied between the conductive strip and layer.

Abstract: An ink jet printhead is comprised of a lower body part (52) having a base section and a plurality of generally parallel spaced projections extending upwardly therefrom and an upper body part (54) having a top section and a corresponding plurality of generally parallel spaced projections extending downwardly therefrom. The top sides of the lower body projections (59) are conductively mounted to the bottom sides of the upper body projections (61) to form sidewalls which define a plurality of ink-carrying channels (70). Strips of a conductive adhesive (57) mount the lower and upper body projections together and a controller (80) is electrically connected to the strips to selectively impart either a positive, zero, or negative voltage to each strip. The lower body part (52) is formed using a piezoelectric material poled in a first direction (P1) generally perpendicular to the channels and the upper body part (54) is formed using a piezoelectric material also poled in the first direction (P2). By applying a positive voltage to a first strip of conductive adhesive and a negative voltage to an adjacent strip of conductive adhesive, first and second electric fields oppositely orientated to each other and normal to the direction of poling are produced in the lower and upper body projections which form first and second sidewalls for the channel, thereby causing the first and second sidewalls to deform in first and second channel expanding directions, respectively.

Abstract: A method of forming an outwardly tapered orifice (16) for a fully assembled ink jet printhead (10). A main body (12) portion and a cover plate (14) for an ink jet printhead (10) are mounted together such that the cover plate (14) covers an ink-carrying channel (22) which axially extends through the main body portion (12). First and second light beam capable of ablating the material used to form the cover plate (14) is generated and an ink-carrying channel (22) communicating orifice extending through the cover plate (14) and tapering outwardly from a front side of the cover plate (14) to a back side (14a) of the cover plate (14) is formed by directing the first and second light beams at the front side (14b) of the cover plate (14) at first and second angles, respectively, whereby the first and second light beams form the outwardly tapered orifice (16).
