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 15):
A liquid supply method of supplying liquid to a liquid ejection head for ejecting liquid within a pressure chamber from an ejection port, the method comprising the steps of:\n pressure-controlling to generate a pressure difference between a supply flow path and a collection flow path so as to supply liquid to the pressure chamber from the supply flow path which communicates with the pressure chamber and to collect liquid within the pressure chamber from the collection flow path which communicates with the pressure chamber; and pressure-compensating to compensate for reduction of pressure within the collection flow path by supplying liquid to the collection flow path in a case where pressure within the collection flow path is a predetermined pressure or lower.
