Abstract:
1. A liquid ejecting apparatus that receives liquid from first and second liquid storing materials that store the same liquid and eject the liquid comprising: first and second ejecting sections in which a plurality of nozzles is formed parallel to a first direction and positions of the nozzles are different to each other in the first direction, an ejecting section group that includes first and second individual ejecting sections in which the positions of the nozzles are different to the first and the second ejecting sections in the first direction and the positions of the nozzles thereof are the same in the first direction, a first flow channel that is branched from the first liquid storing material and communicates with the first ejecting section and the first individual ejecting section, a second flow channel that is branched from the second liquid storing material and communicates with the second ejecting section and the second individual ejecting section, a liquid residual amount detection section that detects first and second residual amounts that are the residual amounts of the liquid that is contained in each of the first and the second liquid storing materials, and a control section that is capable of selecting a first mode that controls so as to be Ra:Rb:Rc:Rd=1:1:1:0, a second mode that controls so as to be Ra:Rb:Rc:Rd=1:1:0:1 and a third mode that controls so as to be Ra:Rb:Rc:Rd=1:1:0.5:0.5, when a frequency of ejecting the liquid using the first and the second ejecting sections and the first and the second individual ejecting sections is Ra, Rb, Rc and Rd, wherein the control section selects any one of the first mode, the second mode and third mode on the basis of the first and the second residual amounts so that exchange timings of the first and the second liquid storing materials are equal to each other.
