Abstract
Abstract An error-compensating technique for scanned data, using a scanner having both a printing device which performs a bi-directional printing operation and a scanner device which moves in the same direction as that of the printing device and performs a scanning function, includes: a special pattern-printing process in which the printing device moves in a preset fixed direction and prints a special pattern-printing process; a pattern-recognizing process in which the scanning device moves in the same direction as that of the printing direction and recognizes the pattern; a pattern-recognizing process in which the scanning device moves in the opposite direction to that of the printing direction and recognizes the pattern; and a position compensation data-yielding process in which position compensation data for the bi-directional scanning data is yielded.
