Abstract
A fluid ejection device includes a fluid slot, a first fluid ejection chamber communicated with the fluid slot and including a first drop ejecting element, a second fluid ejection chamber communicated with the fluid slot and including a second drop ejecting element, a fluid circulation path communicated with the first fluid ejection chamber and the second fluid ejection chamber, and a fluid circulating element within the fluid circulation path.
Claims20
A fluid ejection device comprising:
- a fluid slot comprising fluid;
- a dual fluid ejecting mechanism operatively connected to the fluid slot and comprising different orifices to independently eject drops of the fluid, wherein the dual fluid ejecting mechanism is to combine the drops of fluid into a combined drop of fluid;
- and
- a controller to control operation of the dual fluid ejecting mechanism to eject the plurality of drops of fluid in sizes that are independently determined.
A fluid ejection device comprising:
- a fluid slot comprising fluid;
- a plurality of fluid ejection chambers operatively connected to the fluid slot and each comprising an orifice to eject a drop of the fluid, wherein each drop of fluid comprises a predetermined weight;
- a fluid circulation path to circulate the fluid between the plurality of fluid ejection chambers;
- and
- a fluid circulating element within the fluid circulation path.
A fluid ejection device comprising:
- a first drop ejecting element to eject a first drop of fluid having a first weight;
- a second drop ejecting element to eject a second drop of fluid having a second weight;
- and
- a controller to independently operate the first drop ejecting element and the second drop ejecting element.
