Abstract: A bracket includes a support strut configured to carry the fluid ejection module and an alignment strut coupled to the support strut. The alignment strut is configured to affix to the frame so as to orient the support strut with respect to the frame in each of three orthogonal linear directions and three orthogonal angular directions. The alignment strut includes three alignment mechanisms. Each of the first and second alignment features is held mechanically fixed on the alignment strut in a respective aligned position, and the third alignment mechanism is movable on the alignment strut.

Abstract: A fluid ejection device includes a fluid manifold, a substrate coupled to the fluid manifold, and a fluid distribution structure disposed between the fluid manifold and the substrate. The fluid manifold includes a fluid supply chamber and a fluid return chamber. The substrate defines a flow path including a flow path inlet for receiving fluid, a nozzle for ejecting fluid droplets, and a flow path outlet for channeling away un-ejected fluid. The fluid distribution structure includes a fluid supply channel including a supply inlet fluidically coupled to the fluid supply chamber and a supply outlet fluidically coupled to the flow path. The fluid distribution structure also includes a fluid bypass channel including a bypass inlet fluidically coupled to the fluid supply chamber, a bypass outlet fluidically coupled to the fluid return chamber, and a flow inhibitor between the bypass inlet and the bypass outlet providing a supplemental flow resistance to the fluid bypass channel. The flow inhibitor includes a convergent-divergent throat section.

Abstract: A fluid ejection apparatus includes a fluid distribution layer between a fluid manifold and a substrate. The fluid distribution layer includes fluid supply channels and fluid return channels. Each fluid supply channel receives fluid from the fluid supply chamber and circulates a fraction of the received fluid back to the fluid return chamber through a return-side bypass. The substrate include a plurality of flow paths, each flow path includes a nozzle for ejecting fluid droplets. Each flow path receives fluid from a respective fluid supply channel, and channel un-ejected fluid into a respective fluid return channel. Each fluid return channel can collect the un-ejected fluid from one or more flow paths and a supply-side bypass, and return the collected fluid back to the fluid supply chamber.
