    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.

    摘要: A printing device for jetting a liquid includes a flow path body having a plurality of jetting flow paths, a liquid in the plurality of jetting flow paths, a piezoelectric actuator associated with each jetting flow path, a feed substrate having a plurality of fluid inlets, and a driver configured to apply a voltage pulse to the piezoelectric actuator. The first jetting flow path is adjacent to the second jetting flow path and a fluidic travel distance from the piezoelectric actuator of the first jetting flow path to a nozzle of the second jetting flow path is greater than a speed of sound in the liquid times the break off time of a droplet of the fluid from the nozzle.

    摘要: A method of determining whether a flow path is ready for ejection includes supplying liquid to the flow path, which includes a pumping chamber and a nozzle, after supplying fluid to the flow path, applying energy to an actuator adjacent to the pumping chamber, measuring an electrical characteristic of the actuator to obtain a measured value, and comparing the measured value to a threshold value to determine if the flow path is ready for ejection.
