is automatically performed. (*2) 

Cancel SIM46-24

Check the gray balance and density adjustment result.

Use the test chart (UKOG-0326FCZZ/UKOG-0326FC11) to make a 
copy in the Text/Printed Photo mode, and check the copy gray bal-
ance and density.  

Use SIM46-16 to print the gray balance check pattern, and check the 
patch gray balance and density in the process gray. (If the gray bal-
ance is slightly shifted to Magenta, it is properly adjusted.)

Check that the initial setting of the halftone image correction was properly 
performed. (*2)

Execute the initial setting of the halftone image correction.
(SIM44-21) 

Execute the halftone image correction. (SIM44-26)

Use the test chart (UKOG-0326FCZZ/UKOG-0326FC11) 
to make a copy in the Text/Printed Photo mode, and check
the gray balance and density.

Are the gray balance and den-
sity at the satisfactory level?

End

*1:
When the copy gray balance and density are 
customized and registered as the SERVICE 
target, select the SERVICE target. 
*2:
If the initial setting of the halftone image 
correction is not properly made, satisfactory 
gray balance and density cannot be 
obtained. In this case, check the print engine 
for any problems. 
*3:
If there is any streak or unclear copy on the 
printed check pattern, check the print engine 
for any problems.

Press [OK] key on the operation panel.

According to data of this adjustment, the initial setting of the
halftone image correction is performed.

NOTE:

After pressing [OK] key, the initial setting of the halftone image
correction is started. During the operation, "NOW REGISTER-
ING THE NEW TARGET OF HALFTONE PROCON." is dis-
played. This operation takes several minutes.

After completion of the operation, "PLEASE QUIT THIS
MODE" is displayed.

Do not cancel the simulation until "PLEASE QUIT THIS
MODE" is displayed.

6)

Check the gray balance and density.

(Refer to the item of the copy gray balance and density check.)

7)

Use SIM44-26 to execute the halftone image correction. 
(Forcible execution)

Enter the SIM44-26 mode and press [EXECUTE] key.

[EXECUTE] key is highlighted and the operation is started.

It takes several minutes to complete the operation. After com-
pletion of the operation, "COMPLETE" is displayed.

After completion of the operation, the simulation is canceled.

8)

Use the servicing color test chart (UKOG-0326FCZZ/UKOG-
0326FC11) in the Text/Photo mode (Manual) to check the copy
gray balance and density. (Refer to the item of the copy gray
balance and density check.)

If the copy gray balance and density are not satisfactory, per-
form the following procedures.

9)

Execute the initial setting of the halftone image correction.
(SIM 44-21)

10) Execute the halftone image correction. (Forcible execution)

(SIM44-26)

11) Use the servicing color test chart (UKOG-0317FCZZ/UKOG-

0317FC11) in the Text/Printed Photo mode (Manual) to check
the copy gray balance/density. (Refer to the item of the copy
gray balance and density check.)

Though the above procedures 9) - 11) are performed, the copy gray
balance and density are not in the specified range, there may be
another cause.

Troubleshoot the cause, repair or perform necessary works, and
repeat the adjustment from the beginning.

MX-M1205  ADJUSTMENTS  5 – 55

When the gray balance and the density are unsatisfactory after the
automatic adjustment by selecting the factory target in procedure
4), execute the manual adjustment (SIM46-16)(ADJ11C (2)).

Also when the service target is selected in procedure 7) to execute
the automatic adjustment and a satisfactory result is not obtained,
perform the manual gray balance adjustment (ADJ 11C(2)).

If the gray balance or density is not in the satisfactory level even
after execution of the automatic and manual adjustments, there
may be another cause.

Troubleshoot the cause, repair or perform necessary works, and
repeat the adjustment from the beginning.

 

The gray balance adjustment (Manual adjustment) is used to adjust
the copy density. This is used at the following situation. When the
result of auto adjustment described above is not existing within the
range of reference. When a fine adjustment is required. When
there is request from the user for changing (customizing) the gray
balance.

This manual adjustment is executed only for the gray patch which
could not adjusted properly in the automatic adjustment.

If the gray balance is improper, execute the automatic gray balance
adjustment in advance, and execute this adjustment for better effi-
ciency.
