Abstract
In an inkjet printer of a station-supply type, when ink is supplied from a main tank of an ink cartridge to a sub tank storing ink to be supplied to a recording head, the ink cartridge and the sub tank are connected to each other. The inkjet printer includes: a piston pump including (a) a cylinder which communicates with the main tank and (b) a piston which is slidable in the cylinder in a lengthwise direction thereof and cooperates with the cylinder to form a pressure chamber; a power transmission device which transmits a power to the piston in a state in which the ink cartridge is attached to a frame of the inkjet printer; and a piston-position initializing device which moves the piston to a predetermined initial position.
