Abstract
A droplet ejection apparatus includes droplet ejection units each including a supply port and an ejection port, a common supply flow path, a common discharge flow path, supply flow paths that connect the supply port to the common supply flow path, openable mechanisms provided at the supply flow paths, discharge flow paths that connect the ejection port to the common discharge flow path, one-way valves provided at the discharge flow paths, a pressure applying unit, and a controller. When performing a maintenance operation of a selected droplet ejection unit, the controller applies a pressure with the pressure applying unit so that the pressure in the plural discharge flow paths at the common discharge flow path side with respect to the respective one-way valves is higher than the other side, and opens only the openable mechanism corresponding to the selected droplet ejection unit.
