Loosen the 2 blue screws (2) on the rear regulation plate.
To make parallel with the front regulation plate, move the rear
regulation plate in the clockwize direction and fix the screws.

In the case of diagonal feed 2
Loosen the 2 blue screws (1) on the front regulation plate.
Referring to the degree of diagonal feed, move the regulation
plate in the counterclockwize direction and fix the blue screw.

Loosen the 2 blue screws (2) on the rear regulation plate.
To make parallel with the front regulation plate, move the rear
regulation plate in the counterclockwize direction and fix the
screws.

NOTE: When fixing the rear regulation plate, not to fix it more

closely against the paper.
(The target of the gap between the edge of paper and the
rear regulation plate is about 1.0mm)

NOTE: After completion of the adjustment, check that the front reg-

ulation plate and the rear regulation plate are in parallel to
each other.

Though the off-center adjustment has been made by CIS function,
if the fine adjustment is necessary, perform the following adjust-
ment.
1) Run Sim50-10 using the keypad on the main unit.
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 [DOWN] Key to select "H: 50:

MAINLCT1."

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 0.1mm toward the rear.

-    Increasing the adjustment value by 1 causes the main scan/

print position to shift by 0.1mm 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=+/-2.0 mm.
If the above condition is not met, do the following:

7)

Change the adjustment value. (Enter the 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.
MEMO：For details of the adjustment and checking proce-
dures, refer to the "[5] ADJUSTMENTS AND SETTINGS" on
