Summary:PROBLEM TO BE SOLVED: To prevent clogging of a print head by performing replacement using at least one kind of cleaning liquid for a print head in the way of switching different kinds of ink. SOLUTION: Ink heads 51-54 constituting a print head 500 are fed with liquid, respectively, through passages 71-74. Switching valves 81-84 are arranged in the upstream of the passages 71-74. A switching valve 8x (x: 1-4) is coupled with one end of four passages 9x1-9x4 wherein the passages 9x1, 9x2 are coupled, at the other end thereof, with an ink cartridges 6x. The passages 9x3 is coupled, at the other end thereof, with a container 100 for cleaning liquid principally comprising water and the passages 9x4 is coupled, at the other end thereof, with a container 100' for cleaning liquid principally comprising an organic solvent. These cleaning liquids are fed through the passages 9x3, 9x4 to the switching valve 8x. The switching valve 8x switches the passages 9x1-9x4 to couple one of them with the passage 7x thus supplying a desired liquid selectively to the ink head 5x.
