MX-4101N  ADJUSTMENTS  5 – 77

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: Do not change the setting values of item C, D, E and F. If

these values is changed, density of the high density part is
changed.

If these values is changed, be sure to execute the copy color bal-
ance density adjustment. (Auto adjustment)

 

This adjustment is used to set the color balance and the density in
the single color copy mode to the user's request.
The adjustment is made by changing Y, M, C components of each
color.
This adjustment is not required normally, but executed when there
is a request from the user.
When the default adjustment value is changed, this adjustment is
required in the following cases.
* The CCD unit has been replaced.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.

a. Adjustment procedure
1)

Enter the SIM 46-25 mode.

2)

Select the color to be adjusted with the scroll key.

3)

Select the color (YMC) to be adjusted with the color key.

4)

Enter the adjustment value with 10-key.

5)

Press [OK] key.

6)

Press [Close] key to exit the simulation.

7)

Make a copy in the single color copy mode and check the
copy.

If a satisfactory result is not obtained, return to the SIM 46-25 mode
and change the adjustment value.
Repeat the above procedures until a satisfactory result is obtained.

 

This setting normally not required. When, however, there are case
of following, change the setting.
* When copy in RSPF mode differs from copy in document table

mode.

* When copy density in RSPF mode is low or too high.
* When the RSPF unit is replaced.
* When the RSPF unit is disassembled.
* The CCD unit has been replaced.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.

It is normally not necessary to perform this adjustment.
In the following cases, however, this adjustment must be per-
formed.
* When the copy density differs in the DSPF mode and in the doc-

ument table mode.

* When the copy density differs on the front surface and on the

back surface in the DSPF mode.

7)

Make a copy, and check the copy density.

Repeat the above procedures until a satisfactory result is obtained.

 

a. General
In the user program mode, the user can execute the auto color cal-
ibration (auto adjustment of the copy color balance and density).
This adjustment is to set Enable/Disable of the above user opera-
tion with SIM 26-53.

NOTE: This setting must be set to ENABLE only when the user's

understanding on the automatic adjustment of the copy
color balance and density and the user's operational ability
are judged enough to execute the adjustment.
When set to ENABLE, give enough explanations on the
operating procedures, notes, and operations to the user.

This adjustment is required in the following cases.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When the PCU PWB is replaced.
* When the EEPROM of the PCU PWB is replaced.

b. Setting procedure
1)

Enter the SIM 26-53 mode.

2)

Select ENABLE or DISABLE with 10-key.
When disabling, set to "0" (NO). When enabling, set to "1"
(Yes).

3)

Press [OK] key.

When set to DISABLE, the menu of the user auto color calibration
(automatic adjustment of copy color balance and density) is not dis-
played in the user program mode.
(Auto color calibration by the user (Auto color balance adjustment))
Remark: 
This adjustment is based on the service target color balance set
with SIM 63-7 and SIM 63-8. If, therefore, the above settings are
not properly performed, this adjustment cannot be made properly.
1)

Enter the system setting mode.

2)

Enter the copy setting mode.

3)

Press the auto color calibration key.

4)

Press [EXECUTE] key.
The color patch image (adjustment pattern) is printed out.

5)

Set the color patch image (adjustment pattern) printed in pro-
cedure 4) on the document table.
Set the patch image so that the light density area is on the left
side.
At that time, place 5 sheets of white paper on the above color
patch image (adjustment pattern).

6)

Press [EXECUTE] key, and the copy color balance adjustment
is executed automatically. After completion of the adjustment,
the display returns to the original operation screen.
