LIQUID DISCHARGE DEVICE AND CONTROL METHOD OF LIQUID DISCHARGE DEVICE

To provide a liquid discharge device and a control method of the liquid discharge device, which can remove air in a liquid storage section while suppressing an increase in size of the liquid discharge device.SOLUTION: A liquid discharge device includes: a liquid discharge head which discharges liquid from a nozzle; a liquid storage section which has a storage chamber capable of storing liquid supplied from a liquid supply source to the liquid discharge head; and a carriage on which the liquid discharge head and the liquid storage section are mounted and which can reciprocate in a scanning direction X. The liquid discharge device further includes: discharge flow passages F1, F2 which can discharge air in an upper section within the storage chamber; a connection section 91 which can be connected to/separated from connected sections 71 of the discharge flow passages F1, F2; and a negative pressure generation section which applies negative pressure to the connection section 91. The carriage moves to a prescribed position, so that the connection section 91 is connected to the connected sections 71 of the discharge flow passages F1, F2.SELECTED DRAWING: Figure 21 【課題】液体吐出装置のサイズの拡大を抑制しつつ、液体貯留部内の空気を除去できる液体吐出装置及び液体吐出装置の制御方法を提供する。【解決手段】液体吐出装置は、ノズルから液体を吐出する液体吐出ヘッドと、液体供給源から液体吐出ヘッドに供給される液体を貯留可能な貯留室を有する液体貯留部と、液体吐出ヘッドおよび液体貯留部を搭載して走査方向Ｘに往復移動可能なキャリッジとを備える。液体吐出装置は、貯留室内の上部の空気を排出可能な排出流路Ｆ１，Ｆ２と、排出流路Ｆ１，Ｆ２の被接続部７１に対して接続および離間が可能な接続部９１と、接続部９１に負圧を作用させる負圧発生部と、を備える。キャリッジが所定位置へ移動することで、接続部９１が排出流路Ｆ１，Ｆ２の被接続部７１に接続される。【選択図】図２１
