Abstract:
A fluid ejection device includes a fluid recirculation channel, and a drop generator disposed within the channel. A fluid slot is in fluid communication with each end of the channel, and a piezoelectric fluid actuator is located asymmetrically within the recirculation channel to cause fluid flow from the fluid slot, through the recirculation channel and drop generator, and back to the fluid slot.
