MX-2300/2700 N/G SIMULATION 7 – 87
46-47
Purpose : Setting
Function (Purpose) : Used to set the JPEG compression rate in
Copy/Scanner (PUSH SCAN).
Section : —
Item : Setting
Operation/Procedure
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 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.
* Press [C] key to clear the entered values.
3) When [OK], [
↑
], [
↓
] button, [COLOR], or [BLACK] key is
pressed, the currently entered data are saved to EEPROM and
RAM.

Purpose : Adjustment
Function (Purpose) : Used to execute the magnification adjust-
ment in the scan system (for RSPF).
Section : RSPF/Scanner
Item : Image quality (Size/magnification ratio)
Operation/Procedure
1) Select the set item with [
↑

pressed, the current entered value is saved to EEPROM and
RAM.
* Copying can be performed also by pressing [COLOR]/
[BLACK] key.
* When [CLOSE] button is pressed, the display is shifted to
