Abstract: A liquid ejection apparatus includes: a liquid ejection head having a nozzle which ejects a liquid containing volatile organic compounds to a medium; and a maintenance unit that has a cap, which forms a closed space including an opening of the nozzle, and a suction unit that suctions a fluid from the closed space, and that performs maintenance for discharging the liquid from the nozzle by reducing pressure of the closed space. The maintenance unit is provided with a filter for adsorbing volatile organic compounds contained in the liquid discharged from the liquid ejection head.

Abstract: A liquid ejection apparatus includes a first storage portion capable of storing a liquid supplied from a liquid container, a first open-to-atmosphere channel configured to open the inside of the first storage portion to the atmosphere, a second storage portion capable of storing the liquid supplied from the first storage portion, and a second open-to-atmosphere channel configured to open the inside of the second storage portion to the atmosphere. The liquid ejection apparatus is configured to select either a normal mode or a transport mode. The normal mode is a mode in which the power is switched off with the first open-to-atmosphere channel open and the second open-to-atmosphere channel open. The transport mode is a mode in which the power is switched off with the first open-to-atmosphere channel open and the second open-to-atmosphere channel closed.
