Abstract: A bag-in-box fluid supply may include a bag comprising a spout extending therefrom, the spout including a flange coupled to a surface of the bag and comprising a lip formed on the spout distal to the bag; a box formed around the bag to maintain the bag therein; a wedge to wedge a surface of the box between the lip and a surface of the bag; and a fluid interface to fluidically interface with the spout of the bag, the fluid interface including a fluidic channel and a collar disposed on a first end of the fluidic channel to secure the fluid interface to the spout.

Abstract: A fluid injection module may include a fluid ejection die, a die carrier, a bypass fluid passage in at least one pressure regulator. The fluid ejection die may include nozzle orifices on a front face of the die, first and second fluid passages extending through the die and a microchannel extending from the first fluid passage to the second fluid passage proximate the nozzle orifices to circulate fluid from the first fluid passage to the second fluid passage. Third and fourth fluid passages may extend through the die carrier. The bypass fluid passage may extend from the third fluid passage to the fourth fluid passage while being connected to the first fluid passage and the second fluid passage. The at least one pressure regulator is to induce pressure differential driven fluid flow across the microchannel and across the bypass fluid passage.

Abstract: A fluid supply component for a replaceable fluid supply may include a channel fluidically coupled to a pliable fluid supply bag; a ball housed within the channel; and a gasket to prevent movement of the ball into the fluid supply bag; wherein the valve prevents fluid from entering the fluid supply bag while the fluid supply bag imparts a negative fluidic pressure.

Abstract: A print module may include a printhead die. The printhead die may include a chamber layer having ink chambers and micro-channels formed in the chamber layer. The print module may further include a die carrier including manifold passages through which ink flows to and from the printhead die and dual pressure regulators to flow fluid through the micro-channels of the printhead die.
