Abstract: A connection arrangement is between first and second members pivoted together between open and lockable positions. The first member has a first connector and the second member has a second connector, said connectors being adapted to connect by linear movement between them. The first member has a user-actuatable handle adapted, when the first and second members are in said lockable position: during a first movement of the handle, to engage a latch member of the first member with a catch on the second member; and, during a second movement, to move the first and second connectors with respect to one another in a first linear direction between a disengaged and an engaged position of the connectors. A block element on the first member is arranged to prevent said first and second movements of the handle when said first and second members are not in said lockable position.

Abstract: A print bar for a for a multi-pass printer, the print bar comprising a static part configured to extend across a print area of a print target and a moveable part comprising a print bar beam and printer comprising such a print bar.

Abstract: It is disclosed a printing agent container receptacle that can receive printing agent containers of different sizes. The printing agent container receptacle comprising an actuator that, upon receipt of a longitudinal insertion force on the container defines a stop position of the printing agent container.

Abstract: A printer comprising a printing fluid circuit having at least one printing fluid supplier, an air pressurization system to build up air pressure inside the at least one printing fluid supplier, and a controller is provided, wherein the air pressurization system is fluidly connected to the at least one printing fluid supplier. The controller is to determine the air pressure which has been built up in the at least one printing fluid supplier by the air pressurization system, and to determine a degradation of the air pressurization system depending on the air pressure which has been built up in the at least one printing fluid supplier by the air pressurization system.

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 connector 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 modular print engine unit for a media-wide array printer includes multiple printhead modules, each printhead module having printing dies, and each printing die having multiple nozzles. The modular print engine unit is independently operable relative to another modular print engine unit within the media-wide array printer.

Abstract: A modular print engine unit for independently operable use in a media-wide array printer comprises multiple printhead modules, each printhead module comprising multiple printing dies and each printing die comprising multiple nozzles. The modular print engine unit further comprises a printing fluid supply system to feed, in use, printing fluid to the multiple printhead modules; a print alignment module operable, in use, to align the multiple printhead modules; an error detection module operable, in use, to detect an operating status of the multiple nozzles; and a service sub-system operable, in use, to service the multiple nozzles.

Abstract: In some examples, a media stacker includes a drawer defining a chamber, and a plurality of moving elements to engage media sheets of different sizes as the media sheets are output from a system. The plurality of moving elements are to slide the media sheets to a target position in the drawer, and the plurality of moving elements are to disengage from the media sheets once the media sheets have reached the target position. A plurality of retaining elements are to engage the media sheets of the different sizes as the media sheets slide into the drawer.
