Abstract
A liquid ejecting apparatus provided with N (N≧2) liquid ejecting heads which eject liquid, the liquid ejecting apparatus including a supply path through which liquid is supplied from a tank to the N liquid ejecting heads, a circulation path through which liquid is returned from the liquid ejecting heads to the tank, N opening and closing valves that are installed for each liquid ejecting head on at least one of the supply path and the circulation path, and a liquid sending unit that applies a force sending the liquid from the tank toward the liquid ejecting heads. M opening and closing valves corresponding to M (M<N) liquid ejecting heads selected as cleaning targets are selected to be opened among the N opening and closing valves and the liquid sending unit is driven, to selectively send liquid to the M liquid ejecting heads of the cleaning targets among the N liquid ejecting heads, thereby performing cleaning.
