Abstract

A fluid ejection and scanning assembly includes a drop ejection element that causes fluid to be ejected from an associated nozzle chamber when activated. A first photosensor 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. A second photosensor captures image data based on light reflected from media.
