Abstract
A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid from a nozzle, a liquid storage portion having a storage chamber configured to store the liquid supplied from a liquid supply source to the liquid ejecting head, and a carriage on which the liquid ejecting head and the liquid storage portion are mounted and configured to reciprocate in a scanning direction. The liquid ejecting apparatus includes a discharge flow path configured to discharge air in an upper part of the storage chamber, a coupling portion configured to be coupled to and separated from a coupled portion of the discharge flow path, and a negative pressure generating portion that applies a negative pressure to the coupling portion. When the carriage moves to a predetermined position, the coupling portion is coupled to the coupled portion of the discharge flow path.
