A maintenance mechanism for an ink jet head is provided, which is free from a problem in that remaining ink adhered to a side surface lower end of an ink jet head is adhered to a paper surface during subsequent printing to stain a printed material. The maintenance mechanism for an ink jet head is provided with ink collecting means (22) that is disposed in a side surface of a wiping device (2) for an ink jet head (1) and in the sweeping area of the ink jet head. The main part of the ink collecting means (22) is composed of an ink collecting roller case (26), a shaft (24a) having ends which are respectively supported rotatably by left and right side walls (26a, 26b) of the ink collecting roller case (26), and a pair of ink collecting rollers (24, 24) that are axially supported on the shaft (24a) in the vicinity of the left and right ends thereof. The pair of the ink collecting rollers (24, 24) are arranged such that the insides thereof are partially pressed against the end portions of the ink jet head (1). Each of the ink collecting rollers (24, 24) is formed of a porous elastic member such as felt, sponge, laminated blotting paper, or a known absorbent polymer material.
