5.1.2.6 Skew Correction Adjustment
You must make this adjustment when the output image appears skewed
on the PC monitor or ADF is removed from the ADF rear case. To make
the adjustment, use the scale on the right hinge base which supports the
ADF with the left hinge base. Since the direction for moving the screw
varies depending on how the image is skewed, see the skew patterns
shown below and perform adjustment properly.

If the fed document (output image) is skewed as shown below, loosen
the fixing screw in the hinge base (R) and move it toward “B”, then fix
