MX-M565N  ADJUSTMENTS AND SETTINGS  4 – 58

 

This adjustment is used to execute the fine adjustment in each
mode only when a satisfactory image quality is not obtained by the
basic adjustments ADJ 11E (1) and ADJ 11E (2) or there is a
request from the user. Normally there is no need to execute this
adjustment.

This must be well understood for execution of the adjustment.

 

This adjustment is used to adjust the image density in the low den-
sity area in the printer mode.

Adjust to reproduction setting of the low density image.

This adjustment is required in the following cases.

* When it is required not to reproduce images in the low density

section, or to reproduce low-density images.

* When there is request from the user.

1)

Enter the SIM 67-36 mode.

2)

Enter the adjustment value and press the [OK] key.

In case of increase of the image density on low density part,
increase the adjustment value. For diluting the image density
on low density part, decrease the adjustment value.
 

 

When a tone gap is generated in the high density section in the
printer mode, the setting is changed to lower the density in the high
density section.

This setting is normally not required, however, in the following
cases, a change of setting must be made.

* When a tone gap occurs on part of high density.

* To lower the density in the high density section.

1)

Enter the SIM 67-34 mode.

2)

Select the item A, B with the scroll key.

* If a tone gap occurs on part of high density, set 0 to item A and B

The density of high density part decreases. However, the tone
gap is better.

* In case of more increase of the density on high density part, set 1

to item A and B.

The tone gap may occur in high density part.

NOTE: If the setting values of item B is changed, density of the

high density part is changed.

When these values are changed, be sure to perform the
printer gray balance and density adjustment. (Automatic
adjustment)

 

This adjustment is used to adjust the gray balance and the density
in the monochrome mode, the heavy paper mode, and the gloss
paper mode.

This simulation is used to improve image quality in these modes
and images.

1)

Enter the SIM67-54 mode.

2)

Press [EXECUTE] key.

A4/11" x 8.5" or A3/11" x 17" paper is automatically selected.
The patch image (adjustment pattern) is printed out.

3)

Set the patch image (adjustment pattern) printed in the proce-
dure 2) on the document table so that the thin lines on the
printed patch image (adjustment pattern) are on the left side.
Place 5 sheets of white paper on the printed patch image
(adjustment pattern).
