5) Change value A so that the magnification ratio in the sub scanning
direction is within the specified range.
6) Change value B so that the magnification ratio in the main scan-
ning direction is within the specified range.

7) Make a copy of A3 original with SPF, and measure the magnifica-
tion ratio in the sub scanning direction.
8) Change value C so that the magnification ratio in the sub scan-
ning direction is within the specified range.
9) Press the CA key to cancel the simulation.

adjustment
Before performing this adjustment, check that SIM 50-5 is set to 50. If
not, set it to 50.
not, set it to 50.
This adjustment uses SIM 50-2 and SIM 50-1.
The above two simulations are used in the following manner.
Sim 50-2:
Rough adjustment
SIM 50-1:
Fine adjustment
If the desired value is obtained by SIM 50-2, there is no need to
perform SIM 50-1.
perform SIM 50-1.
