Operation/Procedure
NOTE: Unless a special change is required, keep the default val-
ues except for the following items. For the following items,
change the set values according to the necessity. 
COLOR AE(SW MODE 1 - 7 / TH MAX MONO / TH MAX
COLOR / SW NEWS / TH MODE SCR)
ACS(SIM LEVEL)
1) Select a category to be set with [NEXT] and [BAC] buttons. (In
this example, ACS4 digits or less is set.)
2) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the 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, [COLOR], or [BLACK] key is
pressed, the currently entered data are saved to EEPROM and
RAM.
5) Select a desired button.
The selected button is highlighted and the value is displayed.
(In the default state, [TH_ACS5 ENLARGE] is highlighted.)
6) Enter a new value (000000002 in this example) with 10-key.
* The number of digits is max. 9. The 10th digit cannot be
entered. Entry is made after clearing.
* 10-key: [0] to [9]
* Press [C] key to clear the entered values.
7) When [SET] button is pressed, setting is revised.* The display in the frame of [NEW] is deleted, and the value
entered in the procedure 6 is displayed in the column of
[PRESENT].
* If a new value if less than 9 digits, revision is not made.
* Switch the category sequentially with [NEXT] and [BACK]
buttons.

ment. (Collective adjustment of all the
modes). (Only when FAX is installed)
Section:MFP/FAX
Item: Image quality
Operation/Procedure
1) Enter the set value with 10-key.
* When [C] key is pressed, the entered value is cleared.
2) When [EXECUTE] button is pressed, it is highlighted and the
current set value is saved to EEPROM and RAM. Printing for
the adjustment is started.
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.

1) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
If there is no item over [↓], the display grays out and the opera-
tion is invalid.
* 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.

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.

* Items G are displayed as Display item: Detail of display.
Example: EXECUTE MODE: AUTO

When [EXECUTE] key is pressed after changing and settlement of
exposure adjustment values A to F, the data are saved to EEPROM
and RAM and set to item G at the same time.
