• Color balance target for the  printer color balance adjustment
• Relationship between the factory target and the service target  and the color balance target for the user color balance adjustment in the
printer color balance adjustment (Aut omatic adjustment) (SIM 46-74/76-24)


						

							MX-3610N  ADJUSTMENTS AND SETTINGS  4 – 36
• Factory target in the printer color balance ad
justment (Automatic adjustment) (SIM 46-74/67-24)
By use of SIM 67-26, one of the following color ba lances can be set as the factory color balance target.
Each of the three color balances cannot be changed. (Fixed)
• Service color balance target in the printer color balance adjust- ment (Automatic adjustment) (SIM 46-74/67-24).
For the service color balance target, an optional color balance
can be adjusted with SIM 67-25 and registered with SIM 67-27.
When, however, SIM 67-28 is execut ed, the color balance is set
to the same balance as the factory color balance target set with
SIM 67-26.
• Color balance target in t he user color balance adjustment
This color balance is same as the service color balance target in
the printer color balance adjus tment (Automatic adjustment)
(SIM 46-74/67-24). When, therefore, the service color balance
target is changed, this target  is also changed accordingly.
(Meaning of the service color balance target gamma data and the
purpose of registration)
This procedure must be executed only when the color balance is
customized with SIM 67-25.
If the color balance is not customized, this procedure is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 67-25 according to the users request, use SIM 67-27
to register the service color balance target data by use of the
printed adjustment pattern.
In this case, be sure to use A4 or 11 x 8.5 paper for printing the
adjustment pattern by SIM 67-25.
By this procedure, the service color balance target is revised.
It is recommended to keep the printed adjustment pattern created
with SIM 67-25. This adjustment pattern can be used to register the
same color balance target to another machine.
It is also useful to register the service color balance target data. Do
not fold it and keep it under the circumstances which protect it from
discoloration and dirt.
The service color balance target dat a is basically registered imme-
diately after the color balance adjustment (Manual) with SIM 67-25. If a considerable time has passed 
after completion of the color bal-
ance adjustment (Manual) with SIM 67-25, the color balance of the
adjustment pattern at the time of adjustment differs from the color
balance of the adjustment pattern pr inted after a considerable time.
Never use such a pattern for the adjustment.
The correctness of the service color balance target data can be
judged as follows.
When result of the color valance adjustment (Auto) with selecting
the service color balance target in SIM 67-24 is unsatisfactory or
abnormal.
In that case, the registered service target data for the color balance
adjustment (Auto) may be improper.
This may be caused when an improper or abnormal color balance
adjustment pattern was used to register the service color balance
target data for the color balance adjustment with SIM 67-27.
The color balance adjustment pattern used in registration was
made and printed by the color balance adjustment (Manual) with
SIM 67-25. This procedure may have been executed erroneously.
a. Setting procedure
(Setting procedure of an optional color balance (gamma) as the
service color balance target)
1) Use SIM 67-25 (Printer color balance adjustment (manual adjustment) mode) to print two sheets of the color patch image
(adjustment pattern).
In this case, be sure to use A4 or 11 x 8.5 paper for printing
the adjustment pattern by SIM 67-25.
If the color balance is shifted from the standard, an adjustment
is required. If not, an adjustment is not required. When an
optional color balance is requested by the user, make an
adjustment.

a. General
SIM46-74 is used to perform t he automatic copy color balance and
density adjustment (SIM46-24) and the automatic printer color bal-
ance and density adjustment (SIM67-24) continuously.
Since it is desirable to perform  the copy color balance adjustment
(automatic adjustment) before the automatic printer color balance
and density adjustment, it is advisable to perform the adjustment in
this mode.
This mode is also advisable to effectively perform both of the auto-
matic copy color balance and dens ity adjustment (SIM46-24) and
the automatic printer color balance and density adjustment (SIM67-
24). It saves considerable time when compared with performing
each of the auto copy/printer  color balance and the density adjust-
ment individually.
The color balance adjustment (automatic adjustment) is used to
adjust the copy density of each of Cyan, Magenta, Yellow, and
Black automatically.
When this adjustment is executed, the color balance adjustments
of all the copy/printer modes are revised.

Copy color balance and density adjustment 
(Automatic adjustment)
a. General
The color balance adjustment (automatic adjustment) is used to
adjust the copy density of each of Cyan, Magenta, Yellow, and
Black automatically.
When this adjustment is executed, the color balance adjustments
of all the copy modes are revised.
There are following two modes in the auto color balance adjust-
ment.
1) Auto color balance adjustment  by the serviceman (SIM 46-24
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 copy color balance is lost for some reason, 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.
If the machine condition is dram atically changed, a fatal prob-
lem occurs, or the normal color targets cannot be obtained,
service must recalibrate the machine to specification.
To perform the adjustment, the above difference must be fully
understood.

Copy color balance and density adjustment 
(Manual adjustment)
a. General
The color balance adjustment (M anual adjustment) is used to
adjust the copy density of CMYK. This  is used at the following situ-
ation. When the result of auto adjustment described above is not
existing within the range of re ference. When a fine adjustment is
required. When there is request from  the user for changing (cus-
tomizing) the color balance.
This manual adjustment is execut ed only for the color patch which
could not adjusted properly in the automatic adjustment.
If the color balance is improper, execute the automatic color bal-
ance adjustment in advance, and execute this adjustment for better
efficiency.
