An ink-jet printer has a line-type ink-jet head which has a nozzle row including a plurality of nozzles arranged in an array in a scanning direction; an auxiliary head which is movable in the scanning direction and which has a plurality of nozzles arranged in an array in the scanning direction, and a pitch at which the nozzles of the nozzle row are arranged in the ink-jet head and a pitch at which the nozzles are arranged in the auxiliary head are same. Accordingly, when jetting failure occurs concurrently at nozzles among the plurality of nozzles in the ink-jet head, it is possible to complement, at one time, the failed nozzles by the nozzles in the auxiliary head.
