An ink cleaning apparatus for a printer, includes an ink suction cover configured to suck loose ink and a valve assembly. The valve assembly includes a rotating gear and two pipes connected to the ink suction cover. The rotating gear defines a first receiving hole and a second receiving hole. A first fan and a second fan are mounted in the holes. One pipe connects to the first receiving hole, the other pipe connects to the second receiving hole. The rotating gear rotates to alternatively drive the first fan and the second fan to force air and loose ink in one of the two pipes from the ink suction cover, and drive the other fan to exhaust air with loose ink out of the other pipe.
