Abstract
A fluid ejection system may include a media transport assembly and a printhead assembly having a fluid ejection device opposite the media transport assembly. The fluid ejection device may include a drop ejecting element and a fluid ejection chamber containing the drop ejection element. The fluid ejection chamber has an inlet and an outlet for fluid circulation through the fluid ejection chamber across the drop ejecting element. A particle tolerant architecture is between the inlet and the drop ejecting element.
Claims18
