ABSTRACT:
A liquid droplet ejection apparatus includes an ejection inspecting section for recognizing an inspection pattern printed on a printing unit as an image, and inspecting ejection performance of the functional liquid droplet ejection heads, a workpiece alignment section for aligning a workpiece relative to a set table, a table moving section for moving the set table between the printing area and an alignment position, a unit moving section for moving the printing unit between a retracted position and an inspection position, and a controller for controlling the functional liquid droplet ejection heads, the ejection inspecting section, the table moving section, the unit moving section, and the workpiece alignment section. The controller allows alignment processing of moving the set table to the alignment position and aligning the workpiece and inspection processing of moving the printing unit to the inspection position and performing inspection of the ejection performance to be performed simultaneously.
