摘要： A liquid supply apparatus includes a container mounting portion and a liquid container. The liquid container includes a case configured to store liquid therein, a first movable member positioned in the case, a second movable member positioned on the case, and a retainer configured to retain the second movable member in the first position. The first movable member and the second movable member include a pair of magnetic materials. When the second movable member moves from a first position to a second position, the first movable member is released from a fixed state in which the first movable member is immovably fixed to the case by a magnetic force acting between the pair of magnetic materials.

摘要： A printer comprises an ink-jet head, and a control unit which has a judgment pattern printing control section. When a judgment pattern is printed, the judgment pattern printing control section allows the discharge of ink droplets of a second color to an area on which ink droplets of a first color are to be landed, before discharging the ink droplets of the first color having a small color difference with respect to a color of a medium. Accordingly, the ink discharge malfunction is reliably judged for the nozzle irrelevant to the color of the recording medium and the color of the ink discharged from the ink-jet head.
