ABSTRACT:
An ink jet printer is provided with an ink jet head, an elastically deformable sub-ink tank, an actuator, an ink quantity detection device, controller, and a main ink tank which communicates with the sub-ink tank. The actuator performs a predetermined action, such that the actuator applies a pushing force to the sub-ink tank and then releases the pushing force. The ink quantity detection device detects whether an ink quantity within the sub-ink tank is less than a first value. The controller controls the actuator to perform the predetermined action in a first case where the ink quantity within the sub-ink tank is less than the first value. The controller controls the actuator such that the actuator performs the predetermined action in a second case where the ink quantity within the sub-ink tank is more than the first value and a predetermined condition is satisfied.
