H. Off-center adjustment
(1) Adjustment with the simulation
1) Run SIM 50-10 using the keypad on the main unit.
The following screen appears.
2) This screen allows you to configure the print off-center adjust-

3) On the touch panel, press [
↓] to select "G: 50 :LCC."
4) Enter the desired adjustment value through the numeric key-
pad.
(This value, which defaults to 50, can be adjusted within the
range of 1 to 99).
• Reducing the adjustment value by 1 causes the main scan/
(This value, which defaults to 50, can be adjusted within the
range of 1 to 99).
• Reducing the adjustment value by 1 causes the main scan/
print position to shift by 0.1 mm toward the rear.
• Increasing the adjustment value by 1 causes the main scan/
print position to shift by 0.1 mm toward the front.
5) After entering the adjustment value, press the [EXECUTE] key
on the touch panel to start printing and save the setting.
6)
Check that the adjustment pattern image is printed in the cor-
rect position.
Measure the dimensions of the void areas on the front- and
rear-frame sides of the adjustment pattern image, and make
sure that the following conditions are met:
