1. A liquid ejection system comprising: a carriage to reciprocate a liquid ejection head mounted in a lower portion of the carriage; a nozzle surface provided on a lower surface of the liquid ejection head; a plurality of nozzles provided in the nozzle surface; a case having an opening at a front side; a liquid retainer having a first portion housed in the case and a second portion protruded from the opening of the case; and a liquid supply tube for supplying the liquid from the liquid retainer to the liquid ejection head, the liquid supply tube connected to the liquid retainer in the case, wherein the liquid retainer is comprised of a plurality of liquid retainer chambers arranged linearly along a left-right direction, and the liquid retainer chambers are configured such that the liquid in each of the liquid retainer chambers has a free liquid level that is at a lower height than the nozzle surface, and wherein the nozzles are configured and adapted so that they generate capillary force with respect to the liquid therein, such that the capillary force generated in the nozzles causes liquid to be supplied from the liquid retainer to the liquid ejection head.
