Abstract
The liquid ejection apparatus includes a liquid ejection head, a cap having a closed space forming section forming a closed space, an inflow port through which a humidification fluid flows in, and an outflow port through which the humidification fluid flows out, a humidification fluid storage section storing the humidification fluid, a supply flow path communicating the humidification fluid storage section with the inflow port, a collection flow path communicating the humidification fluid storage section with the outflow port, a pump, a moisture supply section, and a controller. One end of the collection flow path opens at a position in the humidification fluid storage section that is lower than a liquid surface of the humidification fluid. The controller causes the moisture supply section to supply water into the circulation path and drives the pump to cause the humidification fluid to flow in the circulation path.
