Abstract
A method and apparatus for capping the nozzle of a print head of an ink jet recording device for ejecting ink droplets upon a recording medium which comprises capping means which covers the nozzle of the print head of the ink jet recording device for preventing dust from adhering to the nozzle and for eliminating bubbles from getting into the nozzle to prevent the recording ink in the print head from evaporating in combination with purging means composed essentially of suction tube for purging the nozzle of the print head, and which method comprises installing the capping means at a position outside the area of printing of the recording device, and moving the print head to this position when no recording is performed to cap the nozzle face of the print head.
