  • Patent number: 8348368
    Abstract: A method for arraying head assemblies of an inkjet printer and an apparatus used for the method that can reduce a period of time taken to array the head assemblies after the head assemblies are mounted in the inkjet printer by adjusting height and rotation center of each of the head assemblies before the head assemblies are mounted in the inkjet printer, and can improve array precision of the head assemblies by adjusting a position in the X direction and a rotation angle of each of the head assemblies having already adjusted height and rotation center after the head assemblies are mounted in the inkjet printer, by adjusting a position in the Y direction of each of the head assemblies and can control an ink spray time.

  • Publication number: 20100156976
    Abstract: A method and apparatus for arranging heads of an inkjet printer such that ink droplets discharged from respective multiple heads are corrected to zero degrees, X-directional positions of the multiple heads are precisely mechanically arranged, and Y-directional positions of the multiple heads are precisely arranged by software. The inkjet printer head arranging apparatus includes: ink droplet formation units forming ink droplets on a substrate by arranging a plurality of heads in a row and injecting ink to the substrate through the heads; a sensing unit sensing the ink droplets formed on the substrate; a position calculation unit calculating the positions of the sensed ink droplets; a correction value calculation unit calculating position correction values for the heads using the positions of the calculated ink droplets; and a position correction unit correcting the positions of the heads using the calculated position correction values of the heads.
