Fluid ejection and scanning assembly with photosensor activation of ejection elements

摘要

A fluid ejection and scanning assembly (126) includes a drop ejection element (702) that causes fluid to be ejected from an associated nozzle chamber (910) when activated. A first photosensor (710) is coupled to the ejection element and is configured to cause the ejection element to be activated when the photosensor is illuminated by a light source (106). A second photosensor (711) captures image data based on light reflected from media (130).
