Inkjet printer

An inkjet printer, comprising:

• an ink-tank for storing ink;
• a recording head for jetting ink onto a recording medium;
• an ink-supply tube for supplying ink from the ink-tank to the recording head;
• a damper for temporarily storing ink at a midway of the ink-supply tube;
• an ink-feed pump for feeding ink to the damper, the pump disposed between the ink-tank and the damper;
• an ink detection section for detecting whether an ink amount in the damper is greater than or equal to a predetermined amount;
• and
• a control section for performing control to stop the ink-feed pump if a detection result by the ink detection section is greater than or equal to the predetermined amount, and drive the ink-feed pump if the detection result is smaller than the predetermined amount,
• wherein the damper includes an ink chamber for storing ink supplied from the ink supply tube;
• a damper membrane that covers at least one surface of the ink chamber and expands and shrinks, corresponding to an ink amount in the ink chamber;
• and
• a regulating member for regulating an expansion amount of the damper membrane to regulate an ink amount in the ink chamber, the member disposed outside the damper membrane and on an inner side than a maximum expansion position of the damper membrane, and
• wherein the ink detection section includes a moving section that moves according to a displacement of the damper membrane while having contact with an outer surface of the damper membrane;
• and
• a detection sensor for detecting whether the ink amount in the damper is greater than or equal to the predetermined amount, based on a travel distance of the moving section.
