Operation/Procedure
(Lead edge image loss adjustment)
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 void: 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) Set the adjustment value of L4 to 0. (Enter 0 as the adjustment
value of L4, and press [P] key.
3) Set the adjustment value of L5 to 0. (Enter 0 as the adjustment
value of L5, and press [P] key.
4) Make a copy at 200% with the SPF, and calculate the values
of L4 and L5. (Enter 200 as the set value of the copy magnifi-
cation ratio set value (MAGNIFICATION) and press [START]
key.)
5) Enter the above values as the set values of L4 and L5. (Enter
the adjustment values of L4 and L5, and press [P] key.)
(The image scan start timing is determined with the detection
timing of the document lead edge by the detector SPPD.)
If the adjustment result is not satisfactory, perform the above pro-
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.
Repeat procedures 2) - 6) until a satisfactory result is obtained.
(Rear edge image loss adjustment)
Adjust so that the rear edge image loss is 3.5mm. (Change the
adjustment 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 adjust-
ment value of SIDE, 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.
Select 2, and
press [START] key.
Press [START] key, or
press [CUSTOM SETTINGS] key.

Function
(Purpose)
Used to adjust the copy image position and void
area (image loss) on print paper in the copy mode.
(The similar adjustment can be performed with
SIM 50-6.) (SPF mode)
Item Picture quality
L4 = Distance (mm) from the image lead edge position to the
scale of 10mm x 10
L5 = Distance (mm) from the image lead edge position to the
paper lead edge x 10
