摘要： A printhead for an inkjet printer is disclosed. The printhead has one or more a printhead integrated circuits (ICs) with an array of nozzles for ejecting ink. A support structure of the printhead supports the printhead ICs. The support structure has ink conduits for supplying the array of nozzles with ink. Each ink conduit includes cavities distributed along a roof of the ink conduit. An opening to each respective cavity has an upstream edge and a downstream edge. The upstream edge contacts the ink before the downstream edge during initial priming of the ink conduits from an ink supply. The upstream edge has a transition face between the ink conduit and the cavity interior. The transition face is configured to inhibit ink from filling the cavity by capillary action during initial priming of the ink conduit. This causes gas to be trapped within the cavity. The gas acts to compress pressure pulses in the ink.

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 for an inkjet printer that has a printhead integrated circuit (68) with nozzles for ejecting ink, and a support structure (64, 176, 108) for supporting the printhead IC. The support structure has ink conduits (182) for supplying the nozzles with ink and a fluidic damper 200 containing gas for compression by pressure pulses in the ink within the ink conduits to dissipate the pressure pulse. Damping pressure pulses using gas compression can be achieved with small volumes of gas. This preserves a compact design while avoiding any nozzle flooding from transient spikes in the ink pressure.

摘要： An inkjet printer that has an elongate array of nozzles for ejecting ink, a plurality of ejection actuators, each configured to eject ink through one of the nozzles respectively, a plurality of ink conduits aligned with a longitudinal extent of the elongate array of nozzles, the ink conduits extending adjacent the elongate array for supplying the array of nozzles with ink and, a plurality of pulse dampers positioned along each of the ink conduits, each pulse damper being individually in fluid communication with one of the ink conduits and each containing a volume of gas for compression by pressure pulses in the ink conduits. 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： 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.
