[0043] like figure 1 As shown, the multifunction peripheral 11 includes a liquid ejecting device 12 and an image reading device 13 arranged on the liquid ejecting device 12 . The multifunction peripheral 11 has a substantially rectangular parallelepiped shape as a whole in a state where the image reading device 13 covers the upper side of the liquid ejecting device 12 .

[0044] exist figure 1 Among them, the multi-functional peripheral 11 is a device placed on a horizontal plane, and the Z-axis represents the direction of gravity, and the X-axis and the Y-axis represent directions along the horizontal plane perpendicular to the direction of gravity. The X axis, the Y axis, and the Z axis intersect with each other (in this embodiment, they are orthogonal). In the following description, the direction along the X axis is referred to as the scanning direction X, the direction along the Y axis is referred to as the conveyance direction Y, and the direction along the Z axis is refe...

Embodiment approach 2

[0187] In the present embodiment, the liquid ejection device 1100 is configured as an ink jet printer, and ejects ink on the printing paper P to form an image. Ink is one example of a fluid, and one example of a liquid. In addition, in place of the printing paper P, any kind of medium such as a resin film and a cloth may be used as the object of ink ejection.

[0188] like Figure 22 As shown, the liquid ejection device 1100 includes a liquid ejection head 110 , an ink supply unit 120 , a transport mechanism 130 , a movement mechanism 140 , a maintenance unit 150 , and a control unit 190 .

[0189] The liquid ejection head 110 has a nozzle surface 111 on which a plurality of nozzle rows 112 for ejecting ink are provided. The nozzle row 112 is formed by arranging a plurality of nozzles N in the Y-axis direction. The liquid ejection head 110 forms an image on the printing paper P by ejecting ink in the +Z direction from the plurality of nozzles N constituting the nozzle row 1...

Abstract

The invention provides a liquid ejecting apparatus and a control method of the liquid ejecting apparatus capable of removing air in a liquid storage portion while suppressing size enlargement of the liquid ejecting apparatus. The liquid ejecting apparatus includes: a liquid ejecting head that ejects a liquid from a nozzle; a liquid storage unit having a storage chamber capable of storing the liquid supplied from the liquid supply source to the liquid ejection head; a carriage on which the liquid ejection head and the liquid storage unit can be mounted and which reciprocates in the scanning direction (X); discharge flow paths (F1, F2) capable of discharging air in the upper part inside the storage chamber; a connection part (91) that can be connected to and separated from the connected part (71) of the discharge flow paths (F1, F2); and a negative pressure generation unit that causes negative pressure to act on the connection unit (91). The connection section (91) is connected to the section (71) to be connected of the discharge channels (F1, F2) by moving the carriage to a predetermined position.

Description

technical field [0001] The present invention relates to a liquid ejection device including a carriage on which a liquid ejection head and a liquid storage unit are mounted, and a control method of the liquid ejection device. Background technique [0002] As an example of a liquid ejecting device, an ink jet printer that prints by ejecting ink (liquid) supplied from a liquid supply source such as an ink tank to a medium such as paper from a liquid ejecting head is known. In such a printer, a liquid storage unit that stores liquid such as ink supplied from a liquid supply source to the liquid ejection head in the middle of the supply channel path is sometimes mounted on the carriage (for example, patent Reference 1). [0003] For example, in the liquid ejection device described in Patent Document 1, a liquid ejection head and a buffer tank (an example of a liquid storage unit) are mounted on a carriage that reciprocates. The liquid ejecting device is configured to suck the a...
