Make test sheet by drawing parallel lines at 10mm from the both
ends of A3 (11" x 17") white paper as shown below. (These lines
must be correctly parallel to each other.)

must be correctly parallel to each other.)
2) Make a normal (100%) copy of the test sheet on A3 (11" x 17")
paper. (Fit the paper edge with the glass holding plate edge.)
3) Measure the distances (La, Lb, Lc, Ld) at the four corners as
shown below.
When La = Lb and Lc = Ld, no need to perform the procedures 4)

4) Move the mirror base F rail position up and down (in the arrow
direction) to adjust.
(Note) If the rear side rail is used for the adjustment, the scanning
position of the white balance sheet is shifted and "E7-04" may
occur only when scanning with the SPF. Therefore it is ad-
visable to use the front side rail for the adjustment.
