Adjustment (RSPF mode)

Function (Purpose) Used to adjust the scan image density.
Section

Operation/Procedure
1)

Select an adjustment target item with [

] [] key.

2)

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.

3)

Press [OK] key. (The set value is saved.)

This adjustment result affects the image send mode, the copy
mode, and the fax mode.
When the adjustment value is increased, the image density is

Adjustment

Function (Purpose) Copy density and gradation adjustment

(Manual adjustment)

Operation/Procedure
1)

Use [

] [] keys to select a density level to be adjusted.

2)

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.

3)

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 density and gradation corresponding to the adjustment value.

 

46-23

Adjustment/Setup

Function (Purpose) Used to set the density correction of copy

high density section (High density tone gap
supported).

Operation/Procedure
1)

Select an adjustment target item with [

] [] key.

2)

Enter the set value with 10-key. 

3)

Press [OK] key. (The set value is saved.)

* When tone gap is generated in the high density area, set item A

to "0”.
The density of high density part decreases. However, the tone
gap is better.

* To increase the density in the high density area further, set item

A to "1”.
The tone gap may occur in high density part.

NOTE: Do not change the value of item B. If the value is changed,

the density in the high density area is changed.

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.

Function (Purpose) Copy density and gradation adjustment 

(Auto adjustment)

Operation/Procedure
1)

Press [EXECUTE] key.
The patch image (adjustment pattern) is printed out.

2)

Plate the printed adjustment pattern on the document table.

3)

Press [EXECUTE] key.
The copy density and gradation adjustment is performed, then
the adjustment result pattern is printed.

4)

Press [OK] key.
The half tone correction target registration is processed.

] [] key.

2)

Enter the set value with 10-key.

3)

Press [OK] key. (The set value is saved.)

When the adjustment value is increased, reproducibility of the
background and the low density image is increased. When the
adjustment value is decreased, reproducibility of the background
and the low density image is decreased.

Adjustment/Setup

Function (Purpose) Used to adjust the color document repro-

ducibility in the monochrome copy mode.

Operation/Procedure
1)

This simulation is used to adjust the reproducibility of red and yel-
low images when copy a color document of red and yellow images
in the monochrome mode.

When [DEFAULT] key is pressed, it is set to the default value.
When the adjustment values of items A and B are decreased, the
copy density of yellow images is increased. When the adjustment
values are increased, the density is decreased.
When the adjustment value of item A is decreased and the adjust-
ment value of item B is increased, the copy density of red images is
increased. When the adjustment value of item A is increased and
