ABSTRACT:
An inkjet printer includes inkjet heads, pumps, a drive source, a derive shaft, power transmission mechanisms, and a selection unit. The pumps supply ink to the inkjet heads to recover an ink ejection condition of the inkjet heads. The drive source rotates the drive shaft forward or backward. The power transmission mechanisms are disposed between the drive shaft and the pumps, respectively, and switch between a state where a forward rotation force of the drive shaft is transmitted to each pump to bring each pump in a operatable condition and a state where the forward rotation force of the drive shaft is not transmitted to each pump. In conjunction with reverse rotation of the drive shaft, the selection unit selects at least one of the power transmission mechanisms to be brought into a state where the selected power transmission mechanism transmits the forward rotation force of the drive shaft.
