Abstract:
In a printing apparatus including a circulation system circulating a liquid, a volatile component included in the liquid evaporates from an ejection opening and thus characteristics of the liquid involving with concentration or viscosity change. The invention provides a printing apparatus that uses a liquid ejection head including an ejection opening ejecting a liquid, a print element generating energy for ejecting a liquid, and a pressure chamber having the print element provided therein, the printing apparatus including: a circulator configured to circulate the liquid so that the liquid passes through the pressure chamber; and a concentration adjustment unit configured to adjust a concentration of a liquid inside a liquid circulation system by discharging the liquid from the inside of the liquid circulation system and replenishing the liquid into the liquid circulation system from the outside of the liquid circulation system in response to the amount of the discharged liquid.

Claim (Index 29):
The printing apparatus according to  claim 21 ,\n wherein the liquid ejection head includes a first passage being connected to the pressure chamber and supplying a liquid to the pressure chamber and a second passage being connected to the pressure chamber and collecting the liquid from the pressure chamber.
