A nozzle cleaning device blows a cleaning solvent against the nozzle portion of a printer head in an ink jet system printer. The nozzle cleaning device includes an ejecting unit communicated to a cleaning solvent tank through a liquid supply passage. Th ejecting unit includes a plurality of orifices for emitting the cleaning solvent. A side passage is connected to the liquid supply passage. A cylinder is secured to the side passage, and a piston is slidably disposed in the cylinder. When the piston is moved in the cylinder, the cleaning solvent is introduced from the cleaning solvent tank into the cylinder, and then, the cleaning solvent is supplied from the cylinder to the ejecting unit. The amount of the cleaning solvent supplied to the ejecting unit is determined by the stroke of the piston in the cylinder. |
