AR-M351U/M451U, AR-M355U/M455U  SIMULATION  9 - 57

(Lead edge image loss adjustment) (Table 1)

1) Set the front and back surface image loss adjustment values

(LEAD EDGE) as specified below:

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

∗

Set the adjustment value of LEAD to 15. (Enter 15 as the
adjustment value of LEAD EDGE, and press [P] key.)

2) Make a duplex copy at 100% with the SPF, and check that the

lead edge (image loss) is 1.5mm either on the front surface
and the back surface. (Select the duplex mode in the paper
selection mode of SIM 50-6.) (Table 3) (Enter 100 as the copy
magnification ratio set value (MAGNIFICATION), and press
[START] key.)

If the adjustment result is not satisfactory, perform the following
procedures:

3) Change the adjustment values of SIDE1 and SIDE2, and per-

form the adjustment. (Change the adjustment values of SIDE1
and SIDE2, and press [START] key.)

(Shift for the adjustment value change: 0.1mm/step)

(The image scan start timing is determined with the detection
timing of the document lead edge by the detector SPPD.)

Repeat procedures 2) and 3) until a satisfactory result is obtained. 

(Rear edge image loss adjustment)

1) Use the SPF at 100% to make a duplex copy, and check that

the rear edge image loss is 1.5mm on the front and the back
surfaces. (Select the duplex mode in the paper selection mode
of SIM 50-6.) (Enter 100 as the copy magnification ratio set
value (MAGNIFICATION), and press [START] key.)

If the adjustment value is not satisfactory, perform the following
procedure. 

2) Change the adjustment value of TRAIL EDGE. Change the

adjustment value of TRAIL EDGE, and press [START] key. 

Repeat the above procedures until a satisfactory result is
obtained. 

(Front/rear frame direction image loss adjustment)

Set the adjustment value of the front surface and the back surface
(FRONT/REAR) to 20. (Enter 20 as the adjustment value of
FRONT/REAR, and press [P] key.)

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

NOTE: When [P] key is pressed after entering the adjustment

value, the adjustment value is set. When [START] key is
pressed instead, the adjustment value is set and copying is
performed. (Table 2)

(Copy condition setting in this simulation)

∗

To select paper (paper feed tray), perform the following proce-
dures.

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 to be

used with 10-key. (Table 3)

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

∗

To set the copy magnification ratio, perform the following proce-
dure.

1) Enter 2 with 10-key.

2) Press [START] key.

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

4) Press [START] key.

(Table 1)

(Table 2)

(Table 3)

When the total of the above set value and 10 is entered, the mode
is changed to the duplex mode (DD), and a duplex copy is made.

cedures again or adjust with SIM 50-1. 

NOTE: If the adjustment result of the above procedures is not sat-

isfactory, though the adjustment value is changed individu-
ally, the adjustment cannot be completed normally.
