Liquid ejecting apparatus and method of replacing liquid ejecting head

A liquid ejecting apparatus comprising:

• a liquid ejecting head configured to eject a liquid from an ejecting port;
• a liquid supply flow path of which a downstream end portion is attachably/detachably connected to the liquid ejecting head and through which the liquid is supplied from a liquid accommodating portion that accommodates the liquid to the liquid ejecting head;
• an opening/closing valve configured to open and close the liquid supply flow path;
• an atmosphere communication path connected to the liquid supply flow path on a downstream side of the opening/closing valve and configured to communicate with an atmosphere;
• an atmosphere release valve configured to open and close the atmosphere communication path;
• a suction mechanism configured to suck the liquid in the liquid ejecting head;
• and
• a control section that controls operations of the opening/closing valve, the atmosphere release valve, and the suction mechanism,
• wherein the control section executes a discharge operation for discharging the liquid in the liquid ejecting head by performing a suction by the suction mechanism for a predetermined time in a state where the opening/closing valve and the atmosphere release valve are closed prior to a removal of the liquid ejecting head from the downstream end portion of the liquid supply flow path and then opening the atmosphere release valve.
