Abstract
A liquid ejection apparatus includes a wiper carriage 59, and a pressurizing mechanism 60 disposed in a liquid supply path 73 via which a liquid from the liquid storage portion 101 is supplied to an ejection head 20H. The wiper carriage 59 has a wiper 58, which is an example of a maintenance portion. The pressurizing mechanism 60 includes a liquid storage chamber 63 that forms a portion of the liquid supply path 73 and a diaphragm 62, which is an example of a deforming member configured to be deformed to change the volume of the liquid storage chamber 63. The wiper carriage 59 causes the liquid in a nozzle 20N of the ejection head 20H communicating with the liquid storage chamber 63 to flow in a discharge direction by pressing the diaphragm 62 at the pressurized position to pressurize the liquid storage chamber 63.
Claims11
A liquid ejection apparatus comprising:
- a carriage having a maintenance portion that maintains an ejection head ejecting a liquid from a nozzle;
- and
- a pressurizing mechanism disposed in a liquid supply path via which a liquid from a liquid storage portion is supplied to the ejection head, wherein
- the pressurizing mechanism includes a liquid storage chamber that forms a portion of the liquid supply path and a deforming member configured to deform to change a volume of the liquid storage chamber,
- the carriage is configured to press the deforming member at a pressurized position on a movement route, and
- the carriage causes a liquid in the nozzle of the ejection head communicating with the liquid storage chamber to flow in a discharge direction by pressing the deforming member at the pressurized position to pressurize the liquid storage chamber.
