Abstract

A liquid ejecting apparatus includes a liquid flow path which communicates with a nozzle which ejects liquid; a vacuum degassing chamber for removing air bubbles from liquid by depressurizing a part of the liquid flow path; a gas flow path which communicates with the vacuum degassing chamber; a pressurizing chamber which communicates with the gas flow path; and a pump which communicates with the vacuum degassing chamber and the pressurizing chamber through the gas flow path, in which the pump is driven by a sequence selected from a plurality of sequences, and the plurality of sequences include a plurality of depressurizing sequences in which the vacuum degassing chamber is depressurized so that an average pressure of the vacuum degassing chamber becomes different, and a pressurizing sequence in which the pressurizing chamber is pressurized.
