More Information
Summary:The tandem type direct printing apparatus 2 comprises a plurality of printing stations 16a, 16b, 16c and 16d for propelling printing particles 38 born on a bearing member 30 through a plurality of apertures 56 formed on a printing head 50 and for depositing the printing particles 38 on a print medium 8 to form an image. The plurality of printing stations 16a, 16b, 16c and 16d are positioned in the moving direction of the print medium 8 to form the composite image on the print medium 8. The method of the present invention comprises providing a control electrode for deflecting printing particles 70 in adjacent to each aperture 56 in at least one of the plurality of printing stations 16a, 16b, 16c and 16d, the control electrode 70 being positioned at least one side of a direction different from the moving direction of the print medium 38; and applying a voltage to the control electrode 70 so that the printing particles 38 passing through the aperture 56 are deflected to adjust the position of the image formed on the print medium in the perpendicular direction to the moving direction of the print medium 8.
