Abstract:
A liquid ejecting apparatus includes a liquid ejecting unit and a pump. The liquid ejecting apparatus has a supply channel, a return channel, and a communication channel. The supply channel is designed to be able to supply the liquid from a liquid supply source to the nozzle. The return channel has ends connected to the supply channel and forms, together with the supply channel, a circulation channel. The communication channel is connected to the return channel and allows communication between an inside of the return channel and an outside. In a state in which the return channel communicates with the outside through the communication channel, the pump is driven so as to perform a return-channel replacement operation in which the liquid in the return channel is discharged to the supply channel side.

Claim (Index 5):
The liquid ejecting apparatus according to  claim 1 ,\n wherein the return channel has a first end and a second end located on an opposite side to the first end, and the first end is connected to a first position of the supply channel and the second end is connected to a second position of the supply channel closer to the nozzle than the first position, wherein a circulation pump that functions as the pump is disposed between the first position and a connection position of the return channel where the communication channel is connected, wherein, after the return-channel replacement operation has been performed, in a state in which the return channel does not communicate with the outside, the controller causes a circulation operation in which the circulation pump is driven to be performed, and wherein, after the circulation operation has been performed, a supply-channel replacement operation in which the liquid in the supply channel is discharged to the outside is performed.
