Abstract
An image forming apparatus performs periodic line based image transformation in order to correct for irregularities in a mirror and for mechanical disturbances that may occur during the rotation of the mirror. The irregularities of the mirror and the mechanical disturbances that occur during the rotation of the mirror may be measured at installation or may be measured during an operation of the image formation apparatus. The characteristics of the mirror are stored as configuration data, which is referenced by a direction of rotation. The image forming apparatus adjusts image data according to the configuration data. The adjustment may occur through data manipulation in stored image data. Alternatively, the adjustment may occur through the control of a pixel rate used to modulate the image data into a transmitted laser beam. The image data may be received by a host device or the image data may be generated by a scanner.
