More Information
Summary:A liquid supply unit includes a pressure chamber configured to store the liquid, a first supply passage allowing communication between a liquid storage container and the pressure chamber, a second supply passage allowing communication between a liquid injection head and the pressure chamber, and a valve mechanism configured to operate according to a pressure state of the pressure chamber. The valve mechanism prohibits the inflow of the liquid from the first supply passage in a first state where the pressure chamber is within the range of a supply negative pressure, allows the inflow of the liquid from the first supply passage in a second state where the pressure chamber is at a pressure lower than the supply negative pressure, and releases the pressure in the pressure chamber in a third state where the pressure chamber is at a pressure higher than the supply negative pressure by a predetermined value.
