In the manufacturing process of a printer, a check (check associated with the liquid ejecting performance of ejection outlets) on the heads is performed, and the heads are ranked based on the result of the check. The heads that are high in liquid ejecting performance are classified as a first rank; the heads that are low in liquid ejecting performance, as a second rank; and the heads that are lower in ejecting performance than the heads of the second rank, as a third rank. The heads of the third rank are dealt with as not applied to the printer. The heads of the second rank are distributed to a color inkjet head that ejects a color ink or to a pretreatment liquid ejecting head that ejects a colorless liquid. The heads of the first rank are distributed to a black inkjet head that ejects black ink.
