increased.
* It is linked with items C to H of SIM50-6.

*
1: Correction value = (Measurement reference 10mm – 
Lead edge image loss set value) x 10 x (Magnification ratio/
100)
Example of calculation: 140 = (100 – 30) x 10 x (200%/100)
*
2: 2 = (Magnification ratio 200%/100)
If L4 = 0, do not make calculation of SIDE1, but adjust the value of
L5.
If L5 = 0, do not make calculation of SIDE2, but adjust the value of
L4.
If L4 = L5 = 0, the adjustment values of SIDE1 and SIDE2 are the
default values.

Operation/Procedure
1) Select the set item with [↑] and [↓] buttons.
The highlighted section of the set value is switched and dis-
played on the set setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* When [C] key is pressed, the entered value is cleared.
3) When [EXECUTE] button is pressed, it is highlighted and print-
ing for adjustment is started with the current set value.
After completion of printing, [EXECUTE] button returns to the
normal display.
* When [↑], [↓], [OK] button, [COLOR], or [BLACK] key is pressed,
the data are saved to EEPROM and RAM.
* When [C], [CA], [SYSTEM SETTINGS], or [EXECUTE] button is
pressed during printing, the operation is interrupted.
* When the machine returns to the ready state after occurrence of
an interruption, self printing is resumed.

Section: FAX/Scanner
Item: Image quality
Operation/Procedure
1) Use [FAX] button and [SCANNER] button to select the mode.
2) Select the set item with [↑] and [↓] buttons.
The highlighted section of the set value is switched and dis-
played on the set setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
3) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
4) When [OK] button is pressed, the current entered value is
saved to EEPROM and RAM.
* When [↑], [↓] button, [COLOR], or [BLACK] key is pressed,
the data are saved to EEPROM and RAM.
* When [CLOSE] button is pressed, the display is shifted to the
copy basic screen of simulation.

* A to I: The greater the adjustment value is, the greater the image loss is. 1step=0.1mm
