2)
Open the front cabinet.
Turn ON the power switch in the front cabinet of the main unit. 
3)
Turn ON the power switch on the operation panel.
G. Size setting
Execute SIM 26-2 "Size setting" with the key operations of the main
unit.
1)
The size selection menu of the large capacity tray is displayed
on the operation message display.
2)
Select a size button to be set on the message screen.
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-
ment value for each paper feed tray. 
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/
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: 
No adjustment is needed if A - B = 0 
± 3.0 mm.
If the above condition is not met, do the following:
7)
Change the adjustment value. 
(Enter a new adjustment value and press the [OK] key).
Changing the adjustment value by 1 shifts the position by
approximately 0.1 mm. 
Repeat steps 4) to 6) until the condition shown in step 6) is sat-
isfied. 
8)
After you have completed the adjustment, exit from simulation
mode by pressing the [CA] key.
(2) Mechanical adjustment
Since the off-center adjustment is performed when shipping, there
is basically no need to perform this adjustment. If the center is
shifted, however, the simulation is normally used. If the shift is not
removed, perform the following adjustment procedures.
1)
Slowly pull out the tray until it stops.
2)
Loosen the stopper fixing screw (1 pc) on the right lower side
of the tray so that the stopper does not function.
