The present invention provides a color printer belt meander control method. Starting at a predetermined position of a belt, the belt edge is detected for each small interval of the endless belt. Using a difference between the belt edge position data for the first time and the second time, all skew amounts are calculated. From the skew amounts, a skew correction amount is calculated for each interval. The corrected belt edge position data which has been corrected by the skew correction amount is used to calculate an average belt edge position of the entire belt. The difference between this average belt edge position and a desired belt edge position data is deleted from the corrected belt edge position data. The belt edge position data for small intervals is offset corrected so as to obtain a belt edge learning value. According to the belt edge learning value and the belt edge position data, drive of the steering mechanism is controlled. |
