Photosensor activation of an ejection element of a fluid ejection device

摘要

An activation element (700) of a fluid ejection device (126) includes an ejection element (702) that causes fluid to be ejected from an associated nozzle chamber (910) when activated. A photosensor (710) is coupled to the ejection element. The photosensor is configured to cause the ejection element coupled to the photosensor to be activated when the photosensor is illuminated by a light source (106).
