摘要： An inkjet printhead includes: a fluid manifold having a base defining a plurality of fluid outlets and printhead chips attached to the base. Each printhead chip receives printing fluid from a set of the fluid outlets. All fluid outlets are flared with a respect to a width dimension of the printhead chips for facilitating removal of air bubbles.

摘要： A print module including: a cradle having a longitudinal cavity; an elongate printhead assembly positioned in the longitudinal cavity; and a supply assembly slidably movable relative to the cradle along an axis perpendicular to a longitudinal axis of the printhead assembly, the supply assembly having one or more ink couplings for fluidic connection to a printhead of the printhead assembly. The cradle includes a fixed limiter configured for abutment with a reaction plate of the printhead assembly so as to limit movement of the printhead assembly during movement of the supply assembly away from the printhead assembly.

摘要： A method of installing a printhead in a print module includes the steps of: positioning the printhead in a nest of the print module; moving first and second ink couplings towards the nest and into engagement with complementary first and second ink ports positioned at opposite ends of the printhead; and moving a depressor towards the nest and into urging engagement with a portion of the printhead positioned between the first and second ink ports. The first ink coupling, the second ink coupling and the depressor are moved simultaneously, linearly and parallel to each other, thereby to datum the printhead against the nest.

摘要： A print module includes: a cradle having a nest for receiving a printhead; an elongate printhead assembly received in the nest, the printhead assembly including a printhead having first and second ink ports at opposite longitudinal ends thereof; and a supply assembly slidably movable relative to the nest along an axis perpendicular to a longitudinal axis of the printhead. The supply assembly includes first and second ink couplings fast with the supply assembly and connected to respective first and second ink ports. The print module is configured such that movement of the supply assembly disconnects the second ink coupling prior to disconnection of the first ink coupling.

摘要： A print module includes: a cradle defining a longitudinal cavity and an access opening at a first end of the longitudinal cavity; an elongate printhead positioned in the longitudinal cavity; and a guide positioned at the access opening, the guide having an upper surface configured for guiding the printhead into the longitudinal cavity without contacting an ink ejection face of the printhead. The printhead is removable from the cradle via longitudinal sliding movement of the printhead through the access opening.

摘要： A print module includes: a cradle defining a longitudinal cavity and an access opening at a first end of the longitudinal cavity; a printhead carrier positioned in the longitudinal cavity, the printhead carrier comprising a longitudinal rail; and an elongate printhead having a longitudinal overhead hanger for complementary longitudinal sliding engagement with the rail. The printhead is removable from the cradle via longitudinal sliding movement of the printhead relative to the printhead carrier through the access opening.

摘要： A multi-channel fluid coupling for a printhead includes: a body having a first channel and a second channel, the second channel being relatively longer than the first channel; a first inlet port and a first outlet port at opposite ends of the first channel; and a second inlet port and a second outlet port at opposite ends of the second channel. The first and second channels are configured for proportionally modulating a flow resistance of fluids flowing therethrough.

摘要： A print module includes: a cradle defining a longitudinal cavity; an elongate printhead received in the longitudinal cavity, the printhead having a row of printhead contacts; a PCB slidably movable relative to the cradle along a first axis perpendicular to a longitudinal axis of the printhead; and an actuator handle. The actuator handle is configured for reciprocally lowering and raising the PCB and urging the PCB contacts into engagement with the printhead contacts, thereby forming electrical connections between the PCB and the printhead. The PCB electrical contacts are urged along a second axis perpendicular to the first axis and the longitudinal axis of the printhead.

摘要： A print module includes: a cradle having a longitudinal cavity; an elongate printhead assembly positioned in the longitudinal cavity; a supply assembly slidably movable relative to the cradle along an axis perpendicular to a longitudinal axis of the printhead assembly, the supply assembly including a PCB fastened to a PCB mounting plate having a resilient flange configured for clamping engagement with a portion of the PCB containing PCB contacts; and a slide plate slidably movable relative to the cradle along an axis parallel to the longitudinal axis of the printhead assembly. The slide plate is configured for camming engagement with the resilient flange and sliding movement of the slide plate urges the resilient flange into clamping engagement with the portion of the PCB containing PCB contacts, thereby electrically connecting the PCB contacts with the printhead.
