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. A block-unlock element on the second member is arranged to displace the block element to enable said first and second movements of the handle when the first and second members are moved from said open position to said lockable position.

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.

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. A second movement of the handle releases the platform for movement relative to the latch under the action of the bias means. When the latch is in the lockable position, and the print head is installed in the receptor, the first movement of the handle locks the latch in the lockable position and the second movement of the handle releases the platform so that the bias means presses the platform in said first direction to engage said electrical connectors and urge the print head into secure engagement with the receptor.

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.

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. A second movement of the handle releases the platform for movement relative to the latch under the action of the bias means. When the latch is in the lockable position, and the print head is installed in the receptor, the first movement of the handle locks the latch in the lockable position and the second movement of the handle releases the platform so that the bias means presses the platform in said first direction to engage said electrical connectors and urge the print head into secure engagement with the receptor.

A modular print engine unit for independently operable use in a media-wide array printer includes multiple printhead modules, each printhead module including multiple printing dies, and each printing die including multiple nozzles. The modular print engine unit further includes 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.
