    摘要： A fluidic adapter (200) for an ink jet print cartridge (50) having nozzles for ejecting ink in a ejection direction and having an ink inlet port oriented to receive ink in a direction substantially opposite to the ejecting direction. The adapter comprises a body (202) having an outer shell and first and second end portions defining an internal chamber which provides an internal fluid conduit for ink between the first and second ends of the bodys, and a fluidic coupling affixed to the first end of said body and in fluidic communication with the internal chambers. The fluidic coupling is adapted to releasably seal to the inlet port of the print cartridge when the body is engaged with the print cartridge to allow fluid communication between the internal fluid conduit and the inlet port of the print cartridge so as to allow ink flow through the fluidic conduit to the fluidic coupling through the fluid coupling and into the inlet port of the print cartridge in a direction substantially opposite to the ejection direction.

    摘要： An inkjet print cartridge (10) comprises an ink reservoir (12); a substrate (28) with a plurality of ink firing chambers (130) and an ink firing element (70) in each chamber along a top surface thereof a first outer edge (86) along a periphery of substrate; and in close proximity to the ink firing chambers. The ink firing chambers are arranged in first and second arrays and are spaced so as to provide 600 dots per inch printing. An ink channel connects the reservoir with the ink firing chambers and includes a primary channel (52) connected to the reservoir and to a secondary channel. The primary channel allows ink to flow from the ink reservoir, around the first outer edge of the substrate to the secondary channel along the top surface of the substrate. A separate inlet passage (132) defined by a barrier layer (134) for each firing chamber connects the secondary channel with the firing chamber. The separate inlet passage has peninsulas (149) and pinch points (146) formed in the barrier layer to prevent cross-talk and overshoot during high frequency operation. A first circuit (78) on the substrate connects to the firing elements while a second circuit (36) on the cartridge connects to the first circuit means, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz.

    摘要： In a printhead assembly (26), a nozzle plate (44) is bonded directly to special traces (38) formed on a flexible tape automated bonding (TAB) circuit (28), using a commercially available automatic lead bonder (96), to retain the nozzle plate (44) in place on the TAB circuit (28). The TAB circuit (28) is handled in a reel-to-reel film format which is commonly used for electronic chip packaging. In a next step of the reel-to-reel process, an automatic bonder (100) manipulates individual substrates (46), aligns each substrate (46) to an associated nozzle plate (44), and bonds electrodes (54) on the substrate (46) to corresponding leads (30) formed on the TAB circuit (28). In the process of the automated bonder (100) aligning the substrate (46) to the nozzle plate (44), the substrate (46) is automatically aligned with respect to the leads (30) on the TAB circuit. Commercially available automatic bonding equipment can be used to perform the alignment and bonding steps.
