Abstract
A fluid-ejection printhead includes a sparse array of fluid-ejection nozzles through which fluid is ejected onto dot rows parallel to a scan axis of the fluid ejection printhead. The fluid is ejected by more than one fluid-ejection nozzle of the sparse array onto each dot row. The fluid-ejection printhead includes fluid ejection element. Each element can correspond to a pair of the fluid-ejection nozzles through which the fluid is ejected onto a same dot row and include a corresponding pair of fluid-ejection actuators. Each element can instead correspond to one of the fluid-ejection nozzles and include one fluid-ejection actuator.
Claims14
A fluid-ejection printhead comprising:
- a sparse array of fluid-ejection nozzles, the fluid-ejection nozzles through which fluid is ejectable onto dot rows parallel to a scan axis of the fluid-ejection printhead, where the fluid is ejectable by more than one fluid-ejection nozzle onto each dot row;
- and
- a plurality of fluid-ejection elements that each correspond to a pair of the fluid-ejection nozzles through which the fluid is ejectable onto a same dot row and that each include a corresponding pair of fluid-ejection actuators.
A fluid-ejection printhead comprising:
- a sparse array of fluid-ejection nozzles, the fluid-ejection nozzles through which fluid is ejectable onto dot rows parallel to a scan axis of the fluid-ejection printhead, where the fluid is ejectable by more than one fluid-ejection nozzle onto each dot row;
- and
- a plurality of fluid-ejection elements that each correspond to one of the fluid-ejection nozzles and that each include one fluid-ejection actuator.
A fluid-ejection device comprising:
- a fluid supply;
- and
- a fluid-ejection printhead fluidically coupled to the fluid supply and comprising a sparse array of fluid-ejection nozzles through which fluid is ejectable onto dot rows parallel to a scan axis of the fluid-ejection printhead,
- wherein the fluid is ejectable by more than one fluid-ejection nozzle onto each dot row,
- wherein the fluid-ejection printhead further comprises a plurality of fluid-ejection elements that each correspond to a pair of the fluid-ejection nozzles through which the fluid is ejectable onto a same dot row and that each include a corresponding pair of fluid-ejection actuators.
