MX-C250 ADJUSTMENTS 5 – 35
1)
Enter the SIM46-21 mode.
2)
Select the K, C,M or Y mode and press [EXECUTE] key. (A4/
11" x 8.5" paper is automatically selected.)
The color balance adjustment pattern is printed.
3)
Check that the following specification is satisfied or the color
balance is satisfactory.
If not, execute the following procedures.
The print density must be changed gradually from the lighter
level to the darker level. The density changing direction must
not be reversed.
The density level of each color must be almost at the same
level.
Patch B may not be copied.
Patch A must not be copied.
When, however, the color balance is adjusted according to a
request from the user, there is no need to set to the standard
color balance stated above.
4)
Select the K, C,M or Y mode to be adjusted, and select the
adjustment point with the [UP] or [Down] key.
5)
Enter the adjustment value with 10-key and press [OK] key.
The adjustment value is set in the range of (1 - 255). When
SIM 46-24 is used to adjust the automatic color balance and
density, all the set values of this simulation are set to 128.
To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value.
Repeat procedures of 2) - 5) until the condition of 3) is satis-
fied.
6)
Make a copy of the servicing color test chart (UKOG-
0326FCZZ/UKOG-0326FC11) and a user's document accord-
ing to necessity in the normal copy mode, the text/Printed
Photo mode (Manual) to check the adjustment result.
(Refer to the item of the copy color balance/density check.)
7)
Execute SIM 44-21. (Execute the initial setting of the halftone
image correction.)
It takes several minutes to complete the operation. After com-
pletion of the operation, "COMPLETE" is displayed.
(Normal end (Auto transition))
(Abnormal end (Auto transition))
After completion of the operation, the simulation is canceled.
This procedure is to save the copy color balance adjustment
data as the reference data for the halftone correction.
Immediately after execution of ADJ 12C(Color balance adjust-
ment, Manual) with SIM 46-21, be sure to execute this proce-
dure.
