6.1.22 Alignment Specification
Version 1.1
General
*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.

Measurement Item How to Measure
Lead Regi [mm] (P1 to P2) - Reference value *1
Side Regi [mm] (P7 to P8) - Reference value *1
Lead Skew (200 mm) [mm] (P5~P6) - (P3~P4)
Side Skew (400 mm) [mm] (P9~P10) - (P11~P12)
Horizontal R/E Precision (All area) [%] [(P8~P13) - 280]/280x100
Vertical R/E Precision (All area) [%] [(P2~P14) - 400]/400x100
Perpendicularity [mm] 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.
Linearity (Vertical) (400 mm) [mm] 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.
Linearity (Horizontal) (280 mm) [mm] 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.
Linearity (Diagonal) (280 mm) [mm] 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.
Parallelism [mm] (P10~P12) - (P15~P16)
