Liquid supply system, liquid ejecting apparatus, and liquid supply method

A liquid ejecting apparatus, comprising:

• a liquid ejecting unit capable of ejecting a liquid;
• a common mounting portion into which a first liquid storage body capable of storing a liquid and a substitute mounting body which is connected to a second liquid storage body capable of storing a liquid via a relay flow path can be exchangeably mounted;
• a mounting target detection unit capable of detecting whether or not the first liquid storage body and the substitute mounting body are mounted to the common mounting portion;
• a pressurization supply unit which supplies the liquid which is stored in the second liquid storage body to the substitute mounting body under pressure;
• a second liquid storage body mounting portion to and from which the second liquid storage body can be attached and detached;
• a mounting detection unit capable of detecting whether or not the second liquid storage body is mounted to the second liquid storage body mounting portion;
• and
• a control unit which drives the pressure supply unit when a plurality of control conditions are satisfied,
• wherein the control conditions include the liquid which is stored in the second liquid storage body entering a pressurizable state and the mounting target detection unit detecting mounting of the substitute mounting body to the common mounting portion,
• wherein when the mounting detection unit detects that the second liquid storage body is mounted to the second liquid storage body mounting portion, the control unit determines that the liquid which is stored in the second liquid storage body is in the pressurizable state.

A liquid supply method which is carried out by a liquid supply apparatus which includes

• a substitute mounting body which can be mounted, so as to be exchangeable with a first liquid storage body, to a common mounting portion to and from which the first liquid storage body capable of storing a liquid can be attached and detached;
• a relay flow path which communicates a second liquid storage body capable of storing a liquid with the substitute mounting body;
• a second liquid storage body mounting portion to and from which the second liquid storage body can be attached and detached;
• a mounting detection unit capable of detecting whether or not the second liquid storage body is mounted to the second liquid storage body mounting portion;
• and
• a pressurization supply unit which supplies the liquid which is stored in the second liquid storage body to the substitute mounting body through the relay flow path under pressure,
• the method comprising:
• causing the pressurization supply unit to start being driven when the liquid which is stored in the second liquid storage body enters a pressurizable state and the substitute mounting body is mounted to the common mounting portion;
• and
• determining that the liquid which is stored in the second liquid storage body is in the pressurizable state when the mounting detection unit detects that the second liquid storage body is mounted to the second liquid storage body mounting portion.
