11) Insert the slide pin as shown below, and make positioning in the
sub scanning direction. (Initial positioning is completed.)
12) Make a copy in the initial position and check the copy
magnification ratio again.
If the copy magnification ratio is not in the range of 100

1%, perform
the following procedure.
Repeat procedures 12) and 13) until the copy magnification ratio is
within the range of 100

One scale of scribe line corresponds to 0.2%.
13) Change the installing position in the CCD sub scanning direction
to adjust the magnification ratio.
NOTE: Due to the structure of the optical system, when the CCD unit
fixing position is changed with SIM 48-1 set to 50, the copy
magnification ratio is adjusted to the specified level (100

1) Place a scale on the original table as shown below.
2) Enter the SIM 48-1 mode.
3) Make a normal copy and obtain the copy magnification ratios.

4) Check that the copy magnification ratio is within the specified
range (100

If the copy magnification ratio is within the specified range (100
±
1%), the adjustment is completed.
If not, perform the following procedure.
If not, perform the following procedure.
5) Change the scan mode adjustment value of SIM 48-1.
When the adjustment value is increased, the sub scanning direc-
tion copy magnification ratio is increased.
A change in the adjustment value by 1 corresponds to a change in
the copy magnification ratio by about 0.1%.
Repeat procedures 3) – 5) until the coy magnification ratio is
within the specified range (100
tion copy magnification ratio is increased.
A change in the adjustment value by 1 corresponds to a change in
the copy magnification ratio by about 0.1%.
Repeat procedures 3) – 5) until the coy magnification ratio is
within the specified range (100
±
0.28%).
NOTE: Fix the adjustment value of SIM 48-1 adjustment mode (F –
R) to 50.
