Abstract:
1. A liquid ejecting apparatus that ejects liquid supplied from two liquid containers that contain liquid of the same kind, comprising: two discharging portions each of which has a plurality of nozzles aligned in parallel with a first direction, the nozzles of one of the two discharging portions are located at positions in the first direction that are different from positions of the nozzles of the other discharging portion in the first direction; a group of discharging portions that includes two individual discharging portions each of which has a plurality of nozzles, the nozzles of each of the two individual discharging portions being located at positions in the first direction that are different from the positions of the nozzles of the one of the two discharging portions in the first direction and from the positions of the nozzles of the other of the two discharging portions in the first direction, the nozzles of one of the two individual discharging portions being located at the same positions in the first direction as the nozzles of the other individual discharging portion; two flow passages each of which is provided for the corresponding one of the two liquid containers, one of the two flow passages branching from one of the two liquid containers in such a manner that the one liquid container is in communication with the one discharging portion and the one individual discharging portion through the one flow passage, the other flow passage branching from the other liquid container in such a manner that the other liquid container is in communication with the other discharging portion and the other individual discharging portion through the other flow passage; and a controlling section that carries out control in such a manner that, let frequency of use of each of the two discharging portions be denoted as Ra, and let frequency of use of each of the two individual discharging portions be denoted as Rb, a ratio of Ra to Rb satisfies the following relation; Ra:Rb=1:½.
