MX-M565N  ADJUSTMENTS AND SETTINGS  4 – 61

 

Normally, there is no need to perform this adjustment. In the follow-
ing cases, however, this adjustment must be performed. 

* When the user requests to perform the adjustment.

* When the scan image gray balance is defective. 

1)

Enter the Sim. 46-8 mode. 

2)

Select a color to be adjusted with [R], [G], [B] buttons.

3)

Select a mode (low density section or high density section) to
be adjusted with the scroll button.

4)

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

To increase the density of the target color, increase the adjust-
ment value. To decrease the density of the target color,
decrease the adjustment value.

5)

Scan a color document in the color scan mode (Scan to PC or
Scan to e-Mail), and check the density of the received image. 

Check can be made also in the copy mode by the following
procedure. The scanned image, however, is in monochrome. 

5) Press [CLOSE] button in the simulation mode to jump to the
normal copy mode, and make a copy and check the adjust-
ment result.

Switch alternatively between the simulation mode and the nor-
mal copy mode, and adjust and check the adjustment result
with an actual copy. 

Repeat the procedures 3 and 4 until a satisfactory result is
obtained. 

 

Normally, there is no need to perform this adjustment. In the follow-
ing cases, however, this adjustment must be performed. 

* When the user requests to perform the adjustment.

* When the sharpness in the FAX send mode is too low.

Normally this adjustment value may be set to the default and there
is no need to perform the adjustment. When, however, the sharp-
ness of a printed image on the receiving FAX side to too low, per-
form this adjustment.

When performing this adjustment, be sure to check that the receiv-
ing side FAX is normal. 

1)

Enter the Sim. 46-39 mode. 

2)

Select a mode to be adjusted with the scroll button.

3)

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

To increase the sharpness, increase the adjustment value. To
decrease the sharpness, decrease the adjustment value.

4)

Send a FAX message.

5)

Check the sharpness of the received FAX image.

Repeat the above procedures until a satisfactory result is 
obtained.

 

Normally this adjustment is not required. However, perform this
adjustment in the following cases:

* When the user request for performing this adjustment.

* When the FAX send image density is low or high.

Normally, the adjustment value may be set to the default value and
there is no need to make this adjustment. When, however, the
image density on the receiving FAX side is unsatisfactory, perform
this adjustment. 

Before execution of this adjustment, however, be sure to confirm
that the receiving FAX operates normally.

 

1)

Enter the Sim. 46-40 mode, and select the I-FAX or FAX.

2)

Press [EXECUTE] button. 

The adjustment pattern is printed. 

3)

Check the print density in the adjustment pattern. 
If the print density of the adjustment pattern is unsatisfactory,
perform the following procedure. 

4)

Enter the adjustment value with 10-key, and press [OK] button. 
When the adjustment value is increased, the image density is
increased. When the adjustment value is decreased, the
image density is decreased. 

Repeat the procedures 2 thru 4 until a satisfactory result is
obtained.
