摘要： 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.
