(7) Adjustment of Zoom Ratio in the Feeding Direction
("Adjust A3 = Feed Direction Mag. Ratio")
z Requirement
D This adjustment is made for the zoom ratio in the feeding direction.
D A scale is placed on the Original Glass perpendicularly to 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 "0.5% of the actual length.
For 300 mm, the allowance is 300 mm

2. Allow the copy to stand for 3 minutes, then measure the
length to determine the zoom ratio in the feeding direction.
(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.
