9) Measure the length of the copied scale image and calculate the
main scanning direction magnification ratio.
Main scanning direction magnification ratio = Copy image dimen-
sion/Original dimension × 100%
10) Check if the copy magnification ratio is within the specified range
(100 ± 1%).
If the copy magnification ratio is within the specified range, the
adjustment is completed.
If not, perform the following procedures.
(When the copy magnification ratio is over 100 ± 1.0% with SIM
48-1 main scanning direction (manual) adjustment mode copy
magnification ratio is 50)
11) Change the CCD unit fixing position and repeat procedures 7)
11).
Troubles caused by improper work
1) Never touch the other screws than the CCD unit fixing screw.
If the other screws are touched, insufficient resolution, image dis-
tortion, etc. may re resulted, which cannot be adjusted.

Note
With the SIM 48-1 adjustment value set to 50, change the CCD unit
fixing position. If the copy magnification ratio is adjusted within the
specified range (100 ± 1.0%), focus is adjusted as a result. (The
specified resolution is obtained.)
If the copy magnification ratio is within the specified range (100 ±
1.0%) with the SIM 48-1 adjustment value set to 50, but if the
specified resolution is not obtained, perform the following procedures.
1) Set the SIM 48-1 adjustment value to 50.
2) Change the CCD unit fixing position so that the specified resolu-
tion is obtained.
At that time, the main scanning direction copy magnification ratio
may be outside the specified range (100 ± 1.0%).
3) Change the adjustment value of SIM 48-1 to adjust so that the
main scanning direction copy magnification ration is in the
specified range (100 ± 1.0%).
