AR-M550/M620  SIMULATION  8 - 67

(Copy condition in this simulation)

∗

To select paper (paper feed tray), perform the following procedures.

1) Enter 0 with 10-key.

2) Press [START] key. (The mode is changed to the paper feed tray

selection mode.)

3) Enter the number corresponding to the paper feed tray of the tar-

get paper with 10-key. 

4) Press [START] key. (The paper feed tray is selected.)

∗

To set the magnification ratio, perform the following procedure.

1) Enter 2 with 10-key.

2) Press [START] key.

3) Enter the copy magnification ratio with 10-key.

4) Press [START] key.

(Lead edge image loss/void area adjustment)

1) Set the RRGB value of SIM 50-1 to 80 - 99.

2) Set the lead edge image loss adjustment value (LEAD EDG) and

the paper lead edge void adjustment value (DENA) to the values
specified below.

(Standard set value) Lead edge image loss: 1.5mm
Paper lead edge void: 3.5mm (DENA: 35)

∗

Set the adjustment value of LEAD to 15. (Enter 15 as the adjust-
ment value of LEAD and press [P] key.

∗

Set the adjustment value of DENA to 35. (Enter 35 as the adjust-
ment value of DENA and press [P] key.)

3) Set the adjustment value of L1 to 0. (Enter 0 as the adjustment

value of L1, and press [P] key.)

4) Set the adjustment value of L2 to 0. (Enter 0 as the adjustment

value of L2, and press [P] key.)

5) Make a copy at 400%, and calculate the values of L1 and L2.

(Enter 100 as the set value (MAGNIFICATION) of the copy magni-
fication ratio, and press [START] key.) (Place a scale on the docu-
ment table and make a copy.)

6) Enter the above values as the set values of L1 and L2. (Enter the

adjustment values of L1 and L2, and press [P] key.)

If the adjustment result is not satisfactory, perform the above proce-
dures again from the beginning, or use SIM 50-1 to adjust.

NOTE: If a satisfactory result is not obtained with the above proce-

dures, through the adjustment values are changed individually,
the normal adjustment cannot be made. 

Perform procedures 3) to 6) continuously.

(Rear edge void area adjustment)

Adjust so that the rear edge void area is 3.5mm. (Change the adjust-
ment value of TRAIL EDGE, and press [START] key.)

(Front/rear frame direction image loss adjustment)

Set the adjustment value of SIDE to 20. (Enter 20 as the adjustment
value of SIDE, and press [P] key.)

When this adjustment value is changed, the image position is shifted in
the front/rear frame direction.

(Front/rear frame direction void area adjustment)

Adjust so that the total of the front/rear direction void areas is 7.0mm.
(Change the adjustment values of FRONT/REAR, and press [START]
key.)

Front frame void area = 3.5mm

Rear frame void area = 3.5mm

If, as shown above, the front and the rear void areas are not even, use
SIM 50-5 to adjust the image off-center position.
