Abstract:
1. A method for manufacturing a liquid supply system for supplying liquid stored in a liquid reservoir, which is arranged outside a body of a liquid ejection apparatus, to the liquid ejection apparatus, in a state where the liquid reservoir is connected to a liquid retainer that is installed in the liquid ejection apparatus, wherein the liquid reservoir remains connected to the liquid retainer when the liquid ejection apparatus ejects the supplied liquid, a liquid retainer chamber being defined in the liquid retainer in such a manner as to allow communication between the liquid retainer chamber and atmospheric air when the retainer is in an unblocked condition, the method comprising: providing the liquid ejection apparatus having the liquid retainer thereon, the liquid retainer including a liquid retainer chamber and a selectively blockable air hole which, in the unblocked condition, permits atmospheric air to communicate with the liquid retainer chamber but in the blocked condition, blocks atmospheric air from communicating with the liquid retainer chamber, the liquid ejection apparatus and liquid retainer adapted to supply and eject liquid from the liquid retainer when the air hole is in the unblocked condition; blocking the liquid retainer chamber from communicating with the atmospheric air by blocking the air hole; and connecting the liquid retainer to a liquid passage defining body having a liquid passage communicating with the liquid reservoir which is outside the body of the liquid ejection apparatus, wherein the liquid retainer chamber remains blocked from the atmospheric air whenever the liquid ejection apparatus ejects the liquid while liquid is being supplied from the liquid reservoir to the liquid retainer, for ejection by the liquid ejection apparatus.
