MX-7040N  ADJUSTMENTS AND SETTINGS  5 – 67

 

a. General
This adjustment is used to adjust the reproduction capability of the
watermark in the copy/printer mode.
This adjustment is used for watermark documents (primary output).
The result of this adjustment affects the result of watermark print
(secondary output).
In the printer mode, the watermark density can be adjusted by the
printer driver. That adjustment is based on the result of this adjust-
ment.

This adjustment must be performed in the following cases:
* When there is request from the user. (When a satisfactory result

is not obtained from the adjustment in the system setting mode.)

* When there is request from the user. (When a satisfactory result

is not obtained from the adjustment with the printer driver.)

b. Adjustment procedures
1)

Enter the SIM 46-66 mode.

2)

Select the PATTERN mode, then select an adjustment item in
the following list according to the situation.

NOTE: Normally there is no need to adjust the PATTERN mode

(items K and L), the COPY MODE, and the POSITION
mode.

A

WOVEN DEN BK LOW

Watermark density level 
(Color: Black / Adjustment for light 
images)

0 - 255

15

The adjustment value is changed to increase or 
decrease the density of the watermark of 
background documents (primary output).
To increase the watermark density, increase the 
adjustment value.
To decrease the watermark density, decrease the 
adjustment value.

NOTE:

When the adjustment value is increased, 
the watermark area which is originally not 
reproduced becomes difficult to disappear.
When the adjustment value is decreased, 
the watermark area which is originally 
reproduced becomes easy to disappear.

B

WOVEN DEN BK MIDDLE

Watermark density level 
(Color: Black, Density: Standard)

0 - 255

19

C

WOVEN DEN BK HIGH

Watermark density level 
(Color: Black, Density: Dark)

0 - 255

23

D

WOVEN DEN C LOW

Watermark density level 
(Color: Cyan / Adjustment for light 
images)

0 - 255

19

E

WOVEN DEN C MIDDLE

Watermark density level 
(Color: Cyan, Density: Standard)

0 - 255

23

F

WOVEN DEN C HIGH

Watermark density level 
(Color: Cyan, Density: Dark)

0 - 255

27

G

WOVEN DEN M LOW

Watermark density level 
(Color: Magenta / Adjustment for 
light images)

0 - 255

15

H

WOVEN DEN M MIDDLE

Watermark density level 
(Color: Magenta, Density: 
Standard)

0 - 255

18

I

WOVEN DEN M HIGH

Watermark density level 
(Color: Magenta, Density: Dark)

0 - 255

21

J

CONTRAST

Contrast adjustment

0 - 255

2

This is used to adjust the variation in the watermark 
density when the adjustment value of the watermark 
print/contrast adjustment in the system setting is 
changed by 1.
When this value is increased, the variation is also 
increased. When the value is decreased, the 
variation is also decreased.
When the adjustment value is 0, the result of the 
contrast adjustment is not reflected. 
(* The adjustment value must be set to 1 or greater.)

K

HT TYPE (POSI)

For half-tone index watermark type 
positive

42 - 43

42

To reproduce the containing characters of watermark 
copy (secondary output) more clearly, set to 43.
In that case, however, the containing characters of 
the watermark document (primary output) can be 
easily reproduced.

Normally 
set to the 
default.

L

HT TYPE (NEGA)

For half-tone index watermark type 
negative

42 - 43

42

To reproduce the containing characters of watermark 
copy (secondary output) more clearly, set to 43.
In that case, however, the containing characters of 
the watermark document (primary output) can be 
easily reproduced.
