MX-B381/B401  SIMULATION  5 – 63

NOTE: When the compression rate is increased, the HDD capacity
in the document filing mode is decreased. On the other hand, how-
ever, the image quality of some documents may be remarkably
reduced.

 

46-51

Adjustment/Setup

Function (Purpose) Used to adjust the gamma for the copy

mode heavy paper mode and the image
process mode. (Manual adjustment)

Operation/Procedure
1)

Select a target adjustment mode.
Select the gamma adjustment of PAPER (heavy paper mode)
or DITHER (image process mode).

2)

Select a target adjustment density level with [

] [] key.

3)

Enter the set value with 10-key.

4)

printed.

When the image density is insufficient or a background copy is
made in heavy paper copy, change this adjustment value to adjust
the image density.

NOTE: The adjustment values can be reset to the default values

with SIM46-52.

46-63

Adjustment/Setup

Function (Purpose) Used to adjust the density in the low den-

sity section in the image send mode. 
(Different for each mode)

Operation/Procedure
1)

Select a target adjustment item with [

] [] key.

2)

Enter the adjustment value using the 10-key.

3)

Press [OK] key.

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.

 

46-74

Adjustment

Function (Purpose) Copy density and gradation adjustment

(Auto adjustment)/Printer density and gra-
dation adjustment (Auto adjustment)

Operation/Procedure
This simulation is used to perform SIM46-24 and SIM67-24 contin-
uously. 
To perform both the copy density and gradation adjustment (Auto-
matic adjustment) and the printer density and gradation adjustment
(Automatic adjustment), use this simulation for efficient adjustment
operations. 
1)

Press [EXECUTE] key, and the high density process control is
performed. Then, the copy density and gradation adjustment
pattern is printed. 

2)

Plate the printed adjustment pattern on the document table.

3)

Press [EXECUTE] key, and the copy density and gradation
adjustment (automatic adjustment) is performed and the
adjustment result pattern is printed. 

4)

Press [EXECUTE] key, and the printer density and gradation
adjustment pattern is printed. 

5)

Plate the printed adjustment pattern on the document table.

6)

Press [EXECUTE] key, and the printer density and gradation
adjustment (automatic adjustment) is performed and the
adjustment result pattern is printed. 

7)

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

NOTE: The adjustment result becomes effective only when the

adjustment operations in the both modes are completed all
the way. For example, when the copy density and grada-
tion adjustment (automatic adjustment) is performed and
the simulation is canceled, the adjustment result is not
effective.
