MX-3114N ADJUSTMENTS AND SETTINGS 5 – 30
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 and keep it under the circumstances which protect it
from discoloration and dirt.
The service color balance target data is registered 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 color balance target data can be
judges as follows.
When result of the color valance adjustment (Auto) with selecting
the service color balance 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 registration was
made and printed by the color balance adjustment (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 adjustment is not required. When an
optional color balance is requested 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 adjustment
(Manual adjustment) (SIM 46-21) (ADJ 10C (2)) on the docu-
ment table.
The color patch image (adjustment pattern) printed with SIM
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 sheets of white paper on the color patch 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 reversed, 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 registered as the service color balance tar-
get with SIM 63-7.
When the factory color balance target is changed with SIM 63-11,
be sure to execute this procedure.
