*1: When performing adjustments in the heavy paper mode,
load paper in the manual paper feed tray.

 

This adjustment is used to adjust the level of chroma of color
images which are reproduced as monochrome images in the image
send mode (monochrome manual text mode).
This adjustment must be performed in the following cases:
• When there is request from the user.
1)

Enter the SIM 46-55 mode.

2)

Enter the adjustment value with 10-key and press [OK] key.
When the adjustment value is increased, colors dropout
becomes easy to narrow the reproduction range. When the
adjustment value is decreased, color dropout becomes difficult
to widen the reproduction range.

3)

Scan the document in the image send mode (monochrome
manual text mode) and check the adjustment result.

[Effect]
When black characters are fainted by color shift, etc, the black
area is outputted clearly.

[Adverse effect]
Dropout of color sections becomes difficult.

[Effect]
Colors (of low chroma) which are difficult to be dropped out
can be dropped out.

[Adverse effect]
Black characters are fainted or cracked.

MX-4070V  ADJUSTMENTS AND SETTINGS  5 – 57

 

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.
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.

A~I: 
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.
When the adjustment value is increased, the watermark area
which is originally not reproduced becomes difficult to disap-
pear.
When the adjustment value is decreased, the watermark area
which is originally reproduced becomes easy to disappear.

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

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

3)

Enter the adjustment value with 10-key and press [OK] key.

4)

Make a copy, and check the adjustment result.

Note for adjusting the watermark with SIM46-54
When the color balance automatic adjustment is executed with
SIM46-74 or SIM46-24 but the containing characters are repro-
duced, use SIM46-54 to execute the color balance automatic
adjustment for each dither.
However, note the following items.
• When either of item K or L of the PATTERN mode is 42, the

adjustment must be executed for the both modes of WOVEN1
and WOVEN2 of SIM46-54.

• When either of item K or L of the PATTERN mode is 43, the

adjustment must be executed for the both modes of WOVEN3
and WOVEN4 of SIM46-54.

• WOVEN1 and WOVEN2 must be adjusted in a pair as well as

WOVEN3 and WOVEN4.
If it is ignored, the containing characters remain reproduced.

 

Requisite condition before execution of the printer color bal-
ance/density adjustment
Before execution of the printer color balance/density adjustment,
the copy color balance/density adjustment must have been com-
pleted properly.

This adjustment is required in the following cases.
• Basically same as when the copy color balance/density adjust-

ment is required.

• After the copy color balance/density adjustment.

 

The color balance adjustment (auto adjustment) is used to adjust
the print density of each color (Cyan, Magenta, Yellow, Black) auto-
matically with SIM 67-24 or the user program.
When this adjustment is executed, the color balance adjustments
of all the print modes are revised.
There are following two modes in the auto color balance adjust-
ment.
1)

Auto color balance adjustment by the serviceman (SIM 67-24
is used.)

2)

Auto color balance adjustment by the user (The user program
mode is used.) (The color balance target is the service target.)
The auto color balance adjustment by the user is provided to
reduce the number of service calls.
If the print color balance is lost for some reasons, the user can
use this color balance adjustment to recover the balance.
When, however, the machine has a fatal problem or when the
machine condition is greatly changed, this function does not
work effectively.
On the other hand, the auto color balance adjustment by the
serviceman functions to recover the normal color balance
though the machine condition is greatly changed. If the
machine has a fatal problem, repair and adjust it for obtaining
the normal color balance.
To perform the adjustment, the above difference must be fully
understood.

Kinds of 
watermarks

There are two kinds: "Character appearing" and 
"Background appearing."
When a watermark of "Character appearing" is copied, the 
background disappears and the containing characters 
appear.
When a watermark of "Background appearing" is copied, 
the watermark of the character area disappears and the 
containing characters become outline characters.

Principle of 
watermarks

A watermark is composed of two dots: fine dots and rough 
dots.
Since fine dots disappear when copied, they are called 
disappearing patterns. Since rough dots remain when 
copied, they are called remaining patterns.
In a watermark of "Character appearing," the background is 
a disappearing pattern and the containing characters are 
remaining patterns.
In a watermark of "Background appearing," the background 
is a remaining pattern and the containing characters are 
disappearing patterns.

Note for 
watermarks

Watermarks have the following characteristics:
• A watermark is presumed to be synthesized with text 

documents. If it is used with photos or images, the 
containing characters may be seen in the watermark 
document (primary output) or the containing characters 
may not appear properly in the watermark copy 
(secondary output).

• When a watermark is synthesized with newspapers or 

other dark-background documents, the containing 
characters may not appear in the watermark copy 
(secondary output).

• Containing characters may not appear in the watermark 

copy (secondary output) depending on the kind of the 
copier which makes the watermark copy (secondary 
output) and the copy mode.

• Containing characters may not appear clearly in the 

watermark copy (secondary output) depending on the 
copy mode in which the watermark document (primary 
output) is made.

• When the print engine status changes, the containing 

characters may not be concealed properly in the 
watermark document (primary output). In this case, 
follow the procedures below to conceal the containing 
characters.

* Use SIM46-24 to execute the color balance adjustment.
* Use SIM46-54 to execute the color balance adjustment 

for each dither.

* Adjust the watermark print contrast in the system setting.
• Though the watermark of cyan or magenta is selected in 

the black and white mode, the black watermark is 
synthesized.

• For a document which is judged as monochrome with 

ACS selected, though the watermark color is specified as 
cyan or magenta, the black watermark is synthesized.

• The preview screen of the watermark only indicates the 

setting of the watermark color, and does not indicate an 
actual copy image.

• When the document control (printer mode) is used 

together, it is advisable to use "Characters appearing" 
setting. If "Background appearing" setting is used 
together, the detection accuracy of document control 
may be reduced.

• In the printer mode watermark, setting of 1200dpi and a 

watermark cannot be used together.
