Abstract: An inkjet printer has a print bar system comprising a print bar and a plurality of selectively replaceable print heads attached to the print bar. The system comprises a receptor on the bar, for installation of a print head, each print head having a rear face for insertion in said receptor in a first direction. A latch is provided, pivoted on the bar. The latch has a user-actuatable handle adapted, during a first movement thereof, to engage a latch member of the latch with a catch on the bar to lock the latch in a lockable position on the bar. A platform is mounted on the latch with freedom to move with respect to the latch in said first direction when the latch is in said lockable position. The platform has a latch electrical connector, adapted to engage a head electrical convector on the print head, by mutual movement of the connectors in said first direction. A bias means urges the platform in said first direction.

Abstract: A printhead includes a printhead housing and a handle. The handle is movably coupled to the printhead housing. The handle rotatably moves with respect to the printhead housing between a folded position and the non-folded position. In the folded position, the handle extends along a respective housing surface of the printhead housing. In the non-folded position, the handle extends outward from the respective housing surface of the printhead housing.

Abstract: A media-sheet stacking system (10) for stacking media sheets on a device output tray (OT) comprises a kicker (25) to advance a media sheet along the output tray by pushing a trailing edge of the media sheet as it exits the device, and a movable element (32a) arranged to face the output tray across a space that receives media sheets exiting the device. A drive mechanism (33) is provided to drive the movable element in the direction of advance of the media sheet along the output tray.

Abstract: There is disclosed a driver including an elongate shaft and at least one drive assembly. The drive assembly includes a housing which has an orifice for receiving the elongate shaft, and a drive wheel which is located at least partially within the housing. The drive wheel has a bore with a cross-section shaped so that the internal surface of the bore contacts the circumference of elongate shaft when the elongate shaft is inserted into the bore. The bore has at least two fulcrum surfaces so that the drive wheel is pivotable about the elongate shaft. The housing is slideable relative to the elongate shaft.

Abstract: A handoff mechanism for use with a media stacker of a media production apparatus comprises a plurality of kicker units (101) arranged across a width of the handoff mechanism. A common drive mechanism (103) is provided to move the plurality of kicker units (101) between a closed position and an open position. Each kicker unit (101), when in the closed position during use, applies a pressure to any media sheets that are already stacked in a stacker tray (105) while a new media sheet is being fed to the stacker tray. The pressure provided by each kicker unit (101) is independent of the pressure provided by the other kicker units.

Abstract: In one example, a datuming system to position a printhead assembly relative to a component external to the printhead assembly includes a first datum on the printhead assembly to establish a first plane, a first line, and a first point and a second datum on the printhead assembly to establish a second plane orthogonal to the first plane, a second line, and a second point.

Abstract: A positioning assembly is disclosed herein. An example includes a guide shaft having a longitudinal axis and a housing movable along and rotatable about the longitudinal axis of the guide shaft. The housing is also transversely movable and transversely rotatable with respect to the longitudinal axis of the guide shaft. The example of the positioning assembly additionally has a brake mechanism including at least one shoe and a caliper eccentrically mounted on the guide shaft and moveable from a first position that permits movement and rotation of the housing to a second position that impedes movement and rotation of the housing. Other elements and features of the positioning assembly are disclosed herein, as are other examples of positioning assemblies.

Abstract: A shield for an electrical connector comprises a conductive housing configured to enclose an exposed portion of at least one electrical connector. The shield further comprises at least one opening formed in the conductive housing configured to allow a corresponding mating portion of each of the at least one electrical connectors to be exposed. The shield further comprises and a plurality of conductive points located along at least one circumferential path within the conductive housing remote from the at least one opening.
