ABSTRACT:
A pump including a rotor is connected between a print head and an ink cartridge. A housing of the pump is provided with a suction inlet and a discharge outlet. A partition member is disposed in the rotor placed in a hollow defined in the housing. The rotor of the pump is rotated to purge ink from nozzles of the print head. Thereafter, ink is wiped off the nozzle surface of the print head by a maintenance unit. While the ink is being wiped by a maintenance unit, the rotor is rotated at a rotating speed in which ink is not ejected from the print head.
