(Copy magnification ratio adjustment)
1) Select the number corresponding to the copy magnification
ratio adjustment mode to be adjusted with 10-key. (Select one
of 3 - 7.)
2) Press the [START] key.
3) Enter the copy magnification ratio adjustment value with 10-
key.
4) Press the [P] or [START] key.
When [START] key is pressed, copy is performed and the
adjustment value is set simultaneously.
The copy magnification ratio in the sub scan direction can be
adjusted by changing the scan speed (motor RPM).

Purpose Adjustment
Function (Purpose) Used to adjust the copy magnification ratio
in the sub scanning direction.
Section Optical (Image scanning)
Operation/Procedure
When the sub scanning direction image magnification ratio adjust-
ment with SIM 48-1 cannot provide a satisfactory result if a different
magnification ration is set and a copy is made, perform this simula-
tion.
When there is an error in the copy magnification ratio in reduction
copy, change the adjustment value of the high speed mode. When
there is an error in the copy magnification ratio in enlargement
copy, change the adjustment value of the low speed mode.
1) Select the number that corresponds to the mode for which to
make adjustments with 10-key.
2) Press the [START] key.
3) Enter the copy adjustment value with 10-key.
The scanner/SPF motor rotation sped adjustment value is
entered.
