Abstract
An inkjet printer system includes a print head, a sub tank, a pressure controller, and a check valve. The print head is configured to eject ink. The sub tank is connected to the print head and has a pressure control hole. The pressure controller is connected to the pressure control hole to control an inner pressure of the sub tank. The check valve is provided at the pressure control hole to prevent ink in the sub tank from flowing into the pressure control hole from the sub tank.
