3. OPERATION AND TIMING
3. Correcting the Image Skew
The image is likely to be placed askew if the
center of the pattern is different between the rear
and the front. (In the case of Figure 3-430, the
angle θ is not 0.) Here, correction is made so that
the angle θ will be closer to 0.
The correction is made by changing the tilt of
the image position correction mirror, thereby
changing the scanning angle of the laser beam
(Figure 3-431).
In the case of Figure 3-430, the image
position correction mirror is rotated in the direction
shown in Figure 3-431 so that the scanning angle
will be horizontal.
