Operation/Procedure
Select an item to be set with touch panel.
When an item is selected, it is highlighted and the setting change is
saved.

AE_WIDTH AE exposure width
NOTE:
MODE 1 High gamma (high contrast images)
MODE 2 Normal gamma
STOP The image density in 3 - 7mm area at the lead edge is
scanned, and the output image density is determined
according to the scanned density. (The output image
density is even for all the surface.)
REALTIME The densities of the document width are scanned
sequentially, and the output image density is
determined according to the density in each area of
document. (The output image density may not be
even for all the surface.)

PRESCAN The densities of the all surface of document are
scanned sequentially, and the output image density is
determined according to the average of the scanned
densities. (The output image density is even for all the
surface.)
AE WIDTH FULL The document density scan area in the monochrome
auto mode is 3 - 7mm at the document lead edge x
the document width. This is not related to the prescan
mode.
AE WIDTH PART The document density scan area in the monochrome
auto mode is 3 - 7mm at the document lead edge x
100mm width. This is not related to the PRESCAN
mode.

Purpose Adjustment
Function (Purpose) Copy color balance adjustment (Manual
adjustment)
Section
Operation/Procedure
1) Select an adjustment target color with [K][C][M][Y] keys on the
touch panel.
2) Select an adjustment target item with [↑] [↓] key on the touch
panel.
3) Enter the set value with 10-key.
* When the key is pressed, the setting value of each
item can be changed with 1up (1down) collectively.
4) Press [OK] key. (The set value is saved.)
When the adjustment value is increased, the image density is
increased, and vice versa.
When [EXECUTE] key is pressed, the check pattern in printed in
the color balance and density corresponding to the adjustment
value.
