Liquid ejecting apparatus and liquid charging method
A liquid ejecting apparatus includes a liquid ejecting head with one nozzle group for ejecting one type liquid and another nozzle group for ejecting two types of liquid, thereby ejecting multiple types of liquid from the nozzle groups. A cap forms a sealing space that is suctioned by a suction pump. Flow-passages supply the liquid from a liquid container toward the liquid ejecting head. Flow-passage pumps in the downstream side of the liquid container in the flow-passages suction the liquid from the liquid container and discharge the liquid toward the downstream side. A choke valve has a valve chamber at the downstream side of the flow-passage pump to allow the liquid to flow therein. A flexible member changes a volume of the valve chamber by flexing. A discharge hole in an inner portion of the valve chamber is opened or closed by the flexing of the flexible member.
