Abstract:
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 first sensor configured to output a first signal, the first signal selectively having a first value corresponding to the capped state of the capping mechanism or a second value corresponding to the uncapped state of the capping mechanism; and a controller configured to: wherein the controller controls the ventilator to move the air moisturized by the moisturization mechanism to the ejection space when the first uncapped time is shorter than the first predetermined time, and wherein the controller controls the discharger to discharge the liquid through the ejection openings when the first uncapped time is not shorter than the first predetermined time.
