摘要： A printer includes an ink head including a nozzle surface including nozzles, a cap including an end portion contactable with the nozzle surface, a suction device, a memory, and a controller. The memory stores a suction position, a free suction position, and a minute open position located between the suction position and the free suction position. The controller performs a suction process in which the cap is located at the suction position and ink is sucked from the nozzles, and a minute open position process in which the cap is moved toward a minute open position and movement of the cap is stopped with the cap located at a minute open position, after the suction process.

摘要： A valve opening/closing mechanism includes a rotating shaft, first and second cams provided on the rotating shaft and rotatable together with the rotating shaft, first and second valves, and a rotating mechanism that rotates the rotating shaft. The first and second valves each include a flow channel in which ink flows and an opening/closing member at a position at which the opening/closing member contacts the first or second cam, so as to open or close the flow channel, depending on whether the opening/closing member is in contact with the cam. When the rotating shaft is rotated by the rotating mechanism, rotating positions of the first and second cams are at any of first, second, third or fourth positions.

摘要： A liquid supply system includes a liquid supply source, an injection head, a damper in communication with the injection head, a liquid supply path including an end in communication with the liquid supply source and another end in communication with the damper, a liquid supply device supplying the liquid from the liquid supply source toward the damper, a pressure control valve provided between the liquid supply source and the liquid supply device, and a controller controlling the liquid supply device to be actuated or to be stopped. The pressure control valve closes the liquid supply path while the liquid supply device stopped.
