Liquid ejection apparatus

摘要

A liquid ejection apparatus including: a head having an ejection face having ejection openings opposed to an ejection space; a capping mechanism including: a facing portion capable of facing the ejection face; and a space definer configured to define the ejection space with the facing portion and the ejection face, the capping mechanism being switchable between a defining state and an open state; a humid-air supplier configured to perform a humidifying operation for supplying humid air into the ejection space; a sensor portion configured to sense temperature and/or humidity near the head; and a controller configured to, when the humidifying operation performed by the humid-air supplier is discontinued, adjust a next humidifying operation based on at least one of the temperature and the humidity sensed within a period extending from the discontinuation of the humidifying operation to the next humidifying operation.

1. A liquid ejection apparatus, comprising:
a liquid ejection head comprising an ejection face that comprises a plurality of ejection openings for ejecting liquid, an ejection space being opposed to the plurality of ejection openings; a capping mechanism comprising: a facing portion capable of facing the ejection face; and a space definer configured to define the ejection space with the facing portion and the ejection face such that the ejection space is substantially isolated from an outside space, the capping mechanism being switchable between a defining state in which the ejection space is substantially isolated from the outside space and an open state in which the ejection space is open to the outside space; a humid-air supplier configured to perform a humidifying operation for supplying humid air into the ejection space when the capping mechanism is in the defining state; a sensor portion configured to sense at least one of temperature and humidity in a vicinity of the liquid ejection head; and a controller configured to control the liquid ejection head, the capping mechanism, and the humid-air supplier, the controller being configured to, when the humidifying operation performed by the humid-air supplier is discontinued, adjust a next humidifying operation based on (i) at least one of the temperature and the humidity each sensed within a period extending from the discontinuation of the humidifying operation to the next humidifying operation, and (ii) a remaining humidification time that is a length of time for which the humid air should have been supplied into the ejection space if the humidifying operation had not been discontinued.
