AR-M550/M620  SIMULATION  8 - 70

(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 adjust-
ment 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 proce-
dures:

3) Change the adjustment values of SIDE1 and SIDE2, and perform

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 tim-
ing of the document lead edge by the detector SPPD4.)

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 (MAGNIFICA-
TION), and press [START] key.)

If the adjustment value is not satisfactory, , perform the following pro-
cedure. 

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

ment 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.

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 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 procedure.

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.
