<p>A colour registration correcting method of an image formation device. The method includes the steps of arbitrarily selecting one of Y-, M-, C- and K-LSUs to independently drive the selected LSU; generating synchronization-window signals differing by the magnitude of mis-registration among the LSUs with respect to other LSUs except the selected LSU; and driving each driving motor such that the other LSUs meet with each of the sync hronization-window signals. An arbitrary reference LSU is independently driven, to detect the difference in distances between the reference LSU and the respective other LSUs. Also, synchronization-window signals are generated according to the differences and the other LSUs correspond to the synchronization window signals, to thereby easily correct LSU fixing errors of a asynchronization sub-scan direction. Accordingly, the colour registration of a sub-scanning direction may be precisely controlled. <IMAGE></p> |
