Liquid ejection apparatus

摘要

A controller is configured to regularly select one of (i) a moisturization operation with which air moisturized by a moisturization mechanism is moved to an ejection space by a ventilator while a capping mechanism is maintained to be in a capped state and (ii) a liquid discharge operation with which liquid is discharged through ejection openings by a discharger and conduct the selected operation while a recording command is not received. The controller is configured to conduct the liquid discharge operation after the moisturization operation while the recording command is not received.

1. A liquid ejection apparatus comprising:
a head comprising an ejection surface in which a plurality of ejection openings for ejecting liquid are formed; a capping mechanism configured to selectively take a capped state in which an ejection space opposing the ejection surface is covered or an uncapped state in which the ejection space is not covered; a discharger configured to discharge liquid in the head through the ejection openings; an inflow path configured to be connected to the ejection space when the capping mechanism is in the capped state and to allow air flow towards the ejection space passing through the inflow path; an outflow path configured to be connected to the ejection space when the capping mechanism is in the capped state and to allow air flow from the ejection space passing through the outflow path; a moisturization mechanism configured to moisturize the air passing through the inflow path; a ventilator configured to move the air in the inflow path to the ejection space; a wiper configured to remove the liquid on an entire inner surface of the capping mechanism by moving relative to the capping mechanism while contacting the inner surface, the inner surface opposing and distant from the ejection surface when a liquid discharge operation with which the liquid is discharged through the ejection openings by the discharger is conducted and receiving the liquid discharged on account of the liquid discharge operation; and a controller configured to:
maintain the capping mechanism to be in the capped state while a recording command to record an image on a recording medium by ejecting the liquid through the ejection openings is not received;regularly select one of (i) a moisturization operation with which air moisturized by the moisturization mechanism is moved to the ejection space by the ventilator while the capping mechanism is maintained to be in the capped state and (ii) the liquid discharge operation, and conduct the selected operation while the recording command is not received;conduct the liquid discharge operation after the moisturization operation while the recording command is not received; andcontrol the wiper to remove the liquid on the entire inner surface of the capping mechanism after the liquid discharge operation.
