摘要： A printhead for an inkjet printer that has an elongate array of nozzles (68) for ejecting ink and ink conduits for supplying the array of nozzles with ink. The ink conduits extend adjacent the elongate array and have a plurality of pulse dampers individually in fluid communication with the ink conduits, each containing a volume of gas for compression by pressure pulses in the ink conduits, distributed along the length of the elongate array. A pressure pulse moving through an elongate printheads, such as a pagewidth printhead, can be damped at any point in the ink flow line. However, the pulse will cause nozzle flooding as it passes the nozzles in the printhead integrated circuit, regardless of whether it is subsequently dissipated at the damper. By incorporating a number of pulse dampers into the ink supply conduits immediately next to the nozzle array, any pressure spikes are damped at the site where they would otherwise cause detrimental flooding.

摘要： A printhead is provided for an inkjet printer that has a print engine controller for receiving print data and sending it to the printhead. The printhead has a printhead IC for ejecting ink and a support structure for mounting the printhead IC in the printer adjacent a paper path. The printhead IC is mounted on a face of the support structure that, in use, faces the paper path. A flexible printed circuit board (flex PCB) that has contacts for receiving print data mounted to the support structure on a face that does not face the paper path. The bent section reduces the likelihood of trace cracking by holding the flex PCB at a set radius rather than allowing the flex to follow an irregular curve and thereby risking localized points of high stress on the traces.

摘要： The invention relates to a fluidic arrangement for a printer. The arrangement includes an ink tank for storing ink, and an ink distribution assembly in fluid communication with the ink tank for supplying printhead integrated circuits (ICs) positioned thereon with ink from the ink tank. The arrangement also includes a valve arranged in an ink line between the ink distribution assembly and the ink tank, said valve configured to isolate ink in the ink tank from the printhead ICs whenever the printer is powered down. Further included is a pump located downstream from the ink distribution assembly, and a sump arranged in fluid communication with the pump for receiving excess ink from the ink distribution assembly.

摘要： A detachable fluid coupling for connecting an inkjet printhead with an ink supply, the detachable coupling having a fixed valve member defining a valve seat, a sealing collar (146) for sealing engagement with the valve seat (148), a resilient sleeve (126) having one annular end fixed relative to the fixed valve member (128), and the other annular end engaging the sealing collar to bias it into sealing engagement with the valve seat. The coupling also having a conduit opening (150) that is movable relative to the fixed valve member for engaging the sealing collar (146) to unseal it from the valve seat. Unsealing the sealing collar from the valve seat compresses the resilient sleeve (126) such that an intermediate section of the sleeve displaces outwardly relative to the annular ends. With a resilient sleeve that buckles or folds outwardly, the diameter of the coupling is smaller that the conventional couplings that use an annular resilient element that biases the valve shut remaining residual tension. With a smaller outer diameter, the couplings for all the different ink colors can be positioned in a smaller more compact interface.

摘要： A method of fabricating a film used in attaching a printhead integrated circuit to an ink supply manifold is disclosed. An adhesive polymeric film having a protective liner is provided. Photoresist is then deposited onto the protective liner, and the photoresist is photopatterned. Ink supply holes are etched through the adhesive polymeric film and the protective liner, with the photoresist acting as a mask for the etching. Finally, the protective liner including the photoresist is removed from the adhesive polymeric film after the etching step is complete.

摘要： A printhead for an inkjet printer, that has a printhead IC with an array of nozzles for ejecting ink and a support structure for mounting the printhead IC in the printer adjacent a paper path. The printhead IC is mounted on a face of the support structure that, in use, faces the paper path. A flexible printed circuit board (flex PCB) has drive circuitry for operating the array of nozzles on the printhead IC. The drive circuitry has circuit components connected by traces in the flex PCB, and contacts for receiving print data from the print engine controller. The flex PCB being mounted to the support structure at the contacts onto a face that does not face the paper path such that the flex PCB extends through a bent section between the printhead IC and the contacts. The printhead IC and the circuit components are adjacent each other and separated from the contacts by the bent section of the flex PCB. The bent section reduces the likelihood of trace cracking by holding the flex PCB at a set radius rather than allowing the flex to follow an irregular curve and thereby risking localized points of high stress on the traces.

摘要： A printhead that has a printhead integrated circuit (IC) (68) which is elongate and has an array of nozzles for ejecting ink. The printhead also has a support structure 176 for supporting the printhead IC and having ink outlets 186 for supplying the array of nozzles with ink. The ink outlets are spaced along the printhead IC such that the ink outlet spacing (210, 212) decreases at the ends of the printhead IC. By increasing the number of ink outlets near the end regions, the ink supply is enhanced to compensate for the slower priming of the end nozzles. This, in turn, makes the whole nozzle array prime more consistently to avoid flooding and ink wastage from early priming nozzles (or alternatively, unprimed end nozzles).

摘要： A filter for an inkjet printer that has a chamber divided into an upstream section and a downstream section by a filter membrane. An inlet conduit establishes fluid communication between an ink supply and the upstream section. An outlet conduit establishes fluid communication between the downstream section and a printhead. During use at least part of the inlet conduit is elevated relative to the filter membrane. By elevating the inlet conduit relative to the filter membrane, it acts as a bubble trap to retain bubbles that would otherwise obstruct the filter. This allows the filter size to be reduced for a more compact overall design.
