MX3500N ADJUSTMENTS 6 – 55
c. Adjustment procedure
1) Enter the SIM 67-25 mode.
2) Press [EXECUTE] key. (A3 or 11" x 17" paper is automatically
selected.)
The color balance adjustment pattern is printed.
3) Check that the following specification is satisfied or the desired
color balance is obtained.
If the above specification is not satisfied, perform 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 color to be adjusted with the color select key, and
select the adjustment point with the scroll key.
5)
Enter the adjustment value with 10-key and press [OK] key.
The adjustment value is set in the range of 245 – 755 (1 –
999). When SIM 67-24 is used to adjust the automatic color
balance and density, all the set values of this simulation are set
to 500.
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.
When the overall density is low, or when the density is high
and patch A is copied, use the arrow key to adjust all the
adjustment values of A – O to a same level collectively.
Then, adjust each patch density individually. This is an efficient
way of adjustment.
Referring to the black and gray patches, adjust so that each
process (CMY) black/gray patch color balance of A – O
approaches the black/gray patch level as far as possible.
6)
Cancel SIM 67-25.
(For the machine which supports only the GDI mode, the
adjustment is completed.)
7)
Use SIM 64-5 to print the print test pattern.
NOTE: Only for the machine which support the PCL mode.
(For the machine which supports only the GDI mode, this pro-
cedure cannot be used.)
Set each set value to the default and press [EXECUTE] key.
The print test pattern is printed out.
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.
8)
Use SIM 44-26 to execute the half tone image correction (forc-
ible execution).
Enter the SIM 44-26 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.
