MX-3640N  ADJUSTMENTS AND SETTINGS  5 – 30
• Relationship between the factory target and the service target and the color balance target for the user color balance adjustment in the copy
color balance adjustment (Automatic adjustment) (SIM 46-74/46-24)
• Factory target in the copy color balance adjustment (SIM 46-74/46-24)
By use of SIM 63-11, one of the following color balances 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 copy  color  balance adjust-
ment ((Automatic adjustment) SIM 46-74/46-24).
For  the ser vice  color balance t arget,  an option al  color  balance
can be adjusted with SIM  46-21 and reg istered with SIM 63-7.
When, however, SIM 63-8 is executed, the color balance is set to
the  same balan ce  as the factory co lor  balance  target  set  with
SIM 63-11.
• Color balance target in the user color balance adjustment
This color balance is same as the service color balance target in
the copy color balance adjustment (Automatic adjustment) (SIM
46-74/46-24). When, therefore, the service color balance target
is changed, this target is also changed accordingly.
(Meaning of the service co lor balance target gamma data and the
purpose of registration)
This procedure must be executed only when the color balance is
customized with SIM 46-21.
If  the color   balance is  not  customized,  this  procedure  is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 46-21 according to the user's r equest, use SIM 63-7
to  register  the  service colo r  balance  target  data  by  using adjust-
ment pattern that was printed in this mode.
In this case, be  sure to use A4 or  11" x 8.5" paper for printing the
adjustment pattern by SIM 46-21.
By this procedure, the service color balance target is revised.

MX-3640N  ADJUSTMENTS AND SETTINGS  5 – 31
It is recommended to keep the printed adjustment pattern created
with SIM 46-21. 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 an d keep it under the circumstances which protect it
from discoloration and dirt.
The  service  color balance t arget  data  is r egistered  immediately
after the color balance adjustment (Manual) with SIM 46-21.
If a considerable time has passed after completion of the color bal-
ance adjustment (Manual) with SIM 46-21, the color balance of the
adjustment pattern at the time  of adjustment differs from the color
balance of the adjustment pattern printed after a considerable time.
Never use such a pattern for the adjustment.
The  accuracy  of the service colo r  balance  target  data  can be
judges as follows.
When result of the color valan ce adjustment (Auto) with selecting
the service color ba lance target in SIM 46-74/46-24 is unsatisfac-
tory 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 63-7.
The  color  balance  adjustment  pattern  used  in registr ation  was
made and printed by the color balance adjustm ent (Manual)  with
SIM 46-21. 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  46-21  (Copy  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 46-21.
If the color balance is shifted from the standard, an adjustment
is  required.  If  not,  an adjustme nt  is  not  required.  When  an
optional  color  balance  is req uested  by the  user,  make an
adjustment.
2) Enter the SIM 63-7 mode.
3) Press [SETUP] key.
4) Set  the  color  patch  image  (adjustment  pattern)  correctly
adjusted  and printed in the copy color balance adju
stment
(Manual adjustment) (SIM 46-2 1) (ADJ 10C (2)) on the docu-
ment table.
The color  patch  image  (adjustment  pattern)  printed with S IM
64-7 can be used instead. In this case, however, check that the
printed pattern is normal.
(When the color patch image (adjustment pattern) is printed by
SIM 64-7, set the item B (PROC ADJ) to "0 (YES)" and press
[EXECUTE] key to print.)
A  color  patch  image  (adjustment  pattern)  printed by  another
machine can be used.
Set the pattern so that the light density side is on the left side.
Place  5 sheet s  of white p aper  on the color p atch  image
(adjustment pattern).
If  the  color  balance  could  not  be  adjusted  satisfactorily with
SIM 46-21 (Color balance adjustment (Manual)), do not exe-
cute SIM 63-7 to register the service color balance target data.
5) Press [EXECUTE] key.
The color patch image (adjustment pattern) is read.
6) Press  [REPEAT]  key,  set  the  second  color  patch  image
(adjustment pattern), and execute the procedure 5) again.
The  color  balance  (gamma)  target  set  level  of each   color
(KCMY) can be checked with K/C/M/Y keys.
Check that the set level is increased in the sequence of B - Q
(MAX).  If there   is  no variation or   variation  is r eversed,  it  is
judged as abnormal.
In case of an abnormality, repair the problem and try again.
7) Press [OK] key.
The color balance (gamma) of the color patch image (adjust-
ment pattern) used in the procedure 5) is set as the service tar-
get.
(Procedures  to  set  the  service  color  balance  target  and  the
color balance target for the user color balance adjustment to
the same color balance as the factory color balance target)
This procedure must not be executed when the copy color balance
was adjusted with SIM 46-21 to a unique color balance  requested
by the user and it was reg istered as the service color balance t ar-
get with SIM 63-7.
When the factory color balance t arget is changed with SIM 63-11,
be sure to execute this procedure.

A Factory color 
balance (gamma) 
target
There are three kinds of the color balance targets, and each of them is specified according to the machine design. Use SIM 67-26 to 
select one of them as the factory target. The default setting (factory setting) is the color balance (DEF1) which emphasizes color 
reproduction.
B Service color 
balance (gamma) 
target
This target is used when the user requests to customize the color balance to user's desired level. In advance, the user's unique color 
balance must be registered as the service color balance target. The above registration (setting) is made by the serviceman with SIM 
67-25 to adjust the color balance and with SIM 67-27 to register it.
This color balance target is used when the user executes the color balance adjustment. When, therefore, the service color balance 
target is changed, the color balance target of the user's color balance adjustment is also changed. When, however, SIM 67-28 is 
executed, the color balance is set to the factory color balance target set with SIM 67-26. The default setting (factory setting) of the color 
balance is same as the factory color balance target. (Emphasized on color reproduction (DEF1))
If the user does not request for customizing the color balance, be sure to use SIM 67-28 to set the color balance to the factory color 
balance target.

can be adjusted with SIM 67-25 and registered with SIM  67-27.
When, however, SIM 67-28 is executed, the color balance is set
to the same balance as the  factory color balance target set with
SIM 67-26.
• Color balance target in the user color balance adjustment
This color balance is same as the service color balance target in
the  printer colo r  balance  adjustment  (Automatic  adjustment)
(SIM  46-74/67-24).  When, there fore,  the service colo r  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 cust
omized,  this pr ocedure  is not
required.
After completion of the customized color balance adjustment (Man-
ual) with SIM 67-25 according to the user's 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
