  • Fluid ejection die
    Patent number: 11155082
    Abstract: A fluid ejection die includes a fluid slot, laterally adjacent fluid ejection chambers each communicated with the fluid slot and having respective drop ejecting elements therein, and orifices each communicated with a respective one of the laterally adjacent fluid ejection chambers. The laterally adjacent fluid ejection chambers are spaced substantially a same distance from the fluid slot along a same side of the fluid slot, and the orifices communicated with the laterally adjacent fluid ejection chambers are spaced different distances from the fluid slot.
    Type: Grant
    Filed: April 24, 2017
    Date of Patent: October 26, 2021
