ABSTRACT:
An inkjet printer includes: (a) a head unit having ejecting portions and operable to eject a plurality of kinds of inks through the ejecting portions; (b) a discharger for discharging the inks through the ejecting portions; and (c) a communication controller. The discharger includes: (b-1) a cap selectively placeable in a contact state in which the cap is held in contact with the head unit, and in a separate state in which the cap is separated from the head unit; (b-2) a suction pump; and (b-3) a connector connecting the cap and the suction pump. The cap defines therein ink storage chambers in which the respective kinds of inks are to be stored. The connector includes passage definers defining respective discharge passages each communicating the corresponding ink storage chamber and a chamber of the suction pump. The communication controller allows communication between at least two of the ink storage chambers when the cap is placed in the separate state, and inhibits the communication between the at least two ink storage chambers when the cap is placed in the contact state.
