(6) Adjustment of Zoom Ratio in the Crosswise Direction
("Adjust A1 = Lens Full Size Position")
z Requirement
D This adjustment is made for the zoom ratio in the crosswise direction.
D A scale is placed on the Original Glass to run parallel with the Scanner and the length of the scale on
the copy is compared with that of the actual scale. The adjustment must be made so that the difference
between the two dimensions falls within the following specifications.
The difference should be within
For 200 mm, the allowance is 200 mm ⋅ 0.005 = 1.0 mm.

Position
1. Place a scale in parallel with the Original Width Scale and
make a copy.
*Make three copies in full size (⋅ 1.000) mode and using
200-mm-or-wider paper.
*If the scale is of plastic and transparent, place a blank
sheet of paper over it.
2. Allow the copy to stand for 5 minutes, then measure the
length to determine the zoom ratio in the crosswise direc-
tion. (Make the check with the third copy.)
Using the scale, measure the length of the scale on the
copy to find any difference.
*If the zoom ratio deviates from the specifications, go to the
next step.
