*1: The center of the document must be set correctly at the center of the scan.
*2: Specified in the state where the Side Guide is set correctly.
*3: This specification should be applied on the assumption that it is adjustable by the operation on UI
after set up.

(P7 to P8) - Reference value *1
(P5~P6) - (P3~P4)
(P9~P10) - (P11~P12)
[(P2~P14) - 400]/400x100
The shift between P14 and the perpendicular line that extends
from the intersection of the straight line connecting P4 and P6
and the line A.
The maximum shift between the intersections of the vertical line
B with the various horizontal lines and the straight line connect-
ing P10 and P12.
The maximum shift between the intersections of the horizontal
line C with the various vertical lines and the straight line con-
necting P10 and P15.
The maximum shift between the intersections of the diagonal
line D with the various lines and the straight line connecting P17
and P13, or the maximum shift of the intersections of the diago-
nal line E with the various lines and the straight line connecting
P8 and P18, whichever is larger.
