Abstract: A liquid ejecting apparatus includes a liquid ejecting head which ejects liquid from a nozzle that is disposed on a nozzle surface, and an absorption member which is able to contact the nozzle surface, in which it is possible to perform a first contact operation which causes the absorption member to contact the nozzle surface at a position which corresponds to a nozzle region that includes an opening region of the nozzle, and a second contact operation which causes the absorption member to contact the nozzle surface at a position which corresponds to a non-nozzle region that is a region outside of the nozzle region.

Abstract: A liquid ejecting apparatus comprises: a liquid ejecting section that ejects liquid; a supply path through which the liquid is supplied from a liquid supply source to the liquid ejecting section; a movement mechanism that causes the liquid ejecting section to move; and a static mixer that is provided on the supply path and gives rise to a change in a flow of the liquid through the supply path; wherein the movement mechanism causes the liquid ejecting section to move before ejection of the liquid onto a medium by the liquid ejecting section, and the supply path located between the liquid ejecting section and the static mixer moves due to the movement.
