Abstract: A liquid ejecting apparatus includes a liquid supply flow path configured to supply a liquid stored in a liquid supply source to a liquid ejecting portion, a reservoir portion provided in the liquid supply flow path, an on-off valve provided between the liquid supply source and the reservoir portion, a discharge mechanism configured to discharge the liquid in the liquid supply flow path by depressurizing the liquid supply flow path, and a pressure mechanism configured to apply a negative pressure to the interior of the reservoir portion from the exterior. A negative pressure equal to or larger than a negative pressure applied to the interior of the reservoir portion by the discharge mechanism, is applied to the interior of the reservoir portion in a maintenance operation in which the liquid supply flow path is depressurized by the discharge mechanism while the on-off valve is closed.

Abstract: An ink jet recorder includes a support unit configured to support a recording medium, and a mobile unit including a plurality of containers containing inks of identical composition and a head configured to eject the ink supplied from any one of the plurality of containers. The ink jet recorder is configured to record an image on the recording medium in such a manner that the head performs main scanning by ejecting the ink while changing positions in a first direction, and the mobile unit performs sub-scanning by moving in a second direction intersecting with the first direction.

Abstract: A liquid ejecting apparatus includes heating portions for heating liquid, a liquid ejecting head for ejecting the liquid heated by the heating portions, and a maintenance device for performing maintenance of the liquid ejecting head by causing the liquid to be discharged from the liquid ejecting head through sucking operation. The maintenance device performs a first suction for cleaning the liquid ejecting head by causing the head to discharge the liquid, waits until liquid is heated by the heating portions, and then performs a second suction with a suction force weaker than that of the first suction.
