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 method of priming ejection nozzles of a printhead is provided in which inwardly directed force is applied on an exterior wall of a bag containing fluid for distribution to the nozzles so as to reduce an available fluid volume of the bag, thereby causing fluid to be distributed from the bag to the nozzles, and a biasing member in the bag is caused to apply outwardly directed force on an interior wall of the bag so as to restrain the reduction of available fluid volume of the bag only once the available fluid volume of the bag has been reduced to a predetermined volume. The printhead is a pagewidth printhead having a pagewidth of greater than 100 millimetres.

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.
