Liquid ejecting apparatus and liquid ejecting method

A liquid ejecting method for a liquid ejecting apparatus,

• the liquid ejecting apparatus including
• a conveyor configured to convey a medium in a conveyance direction,
• a carriage configured to move in a carriage movement direction intersecting the conveyance direction at a position facing the medium conveyed in the conveyance direction,
• a head provided on the carriage and including at least one nozzle configured to eject a liquid to the medium in a continuous flow, make the continuous flow into droplets, and cause the continuous flow to collide with the medium in a form of droplets,
• a liquid storage configured to store the liquid to be sent to the nozzle, and
• a liquid sending unit configured to send the liquid in the liquid storage to the nozzle continuously,
• the liquid ejecting method comprising:
• using the liquid storage whose volume is larger than a volume of the liquid ejected from the nozzle during one time of movement of the carriage in the carriage movement direction;
• and
• when the liquid is ejected from the nozzle, continuously sending the liquid in the liquid storage to the nozzle by the liquid sending unit while restricting a pressure fluctuation within a predetermined pressure range during one time of movement of the carriage in the carriage movement direction, wherein
• the liquid sending unit sends the liquid to the nozzle by a piston moving in the liquid storage in a first direction and a second direction opposite to the first direction, and
• the piston moves only in one of the first direction and the second direction during one time of movement of the carriage in the carriage movement direction.
