Abstract:
Ink is supplied to a print head through a pressure compensation mechanism and a common collection flow path in a case where a predetermined differential pressure or higher between a pressure in a common supply flow path of the print head and a pressure in a common collection flow path of the print head is generated. As a result, liquid refillability for the liquid ejection head is improved while retaining a liquid circulating function in the liquid ejection head so as to stabilize a liquid ejecting state in the liquid ejection head.

Claim (Index 11):
The liquid supply apparatus according to  claim 6 , further comprising a switching unit configured to switch between (i) a first form in which a third position in a downstream side of the first pressure control section in the supply flow path in a liquid supplying direction is connected to one side of the pressure chamber and a fourth position in an upstream side of the second pressure control section in the collection flow path in a liquid collecting direction is connected to the other side of the pressure chamber and (ii) a second form in which the third position is connected to the other side of the pressure chamber and the fourth position is connected to the one side of the pressure chamber.
