Printer gray balance adjustment 
(Manual adjustment)
a. General
The gray balance adjustment (Manual adjustment) is used to adjust
the printer density. This is used at the following situation. When the
result of auto adjustment described above is not existing within the
range of reference. When a fine adjustment is required. When
there is request from the user for changing (customizing) the gray
balance.
In this manual adjustment, adjust only the gray patch which could
not adjusted properly in the automatic adjustment.
If the gray balance is improper, execute the automatic gray balance
adjustment in advance, and execute this adjustment for better effi-
ciency.
b. Adjustment procedure
1)
Enter the SIM 67-25 mode.
2)
Press [EXECUTE] key. (A4/11" x 8.5" or A3/11" x 17" paper is
automatically selected.)
The gray balance adjustment pattern is printed.
3)
Check that the following specification is satisfied or the gray
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.
Patch B may not be copied.
Patch A must not be copied.
When, however, the gray balance is adjusted according to a
request from the user, there is no need to set to the standard
gray balance stated above.
4)
Enter the adjustment value with 10-key and press [OK] key.
The adjustment value is set in the range of (1 - 999). When
SIM 67-24 is used to adjust the automatic gray 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) - 4) 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 - Q (MAX) to a same level collectively.
Then, adjust each patch density individually. This is an efficient
way of adjustment.
5)
Check the gray balance and density.
(Refer to the item of the printer gray balance and density
check.)
NOTE:
If the gray balance is customized, use SIM 67-27 to register
the gray balance as the service target.
If the gray balance is not customized, this procedure is not
required.
If the customized gray balance is registered as the service tar-
get, the automatic gray balance adjustment can be made in
the next gray balance adjustment.
YES
NO
Start
Execute ADJ11E(2) (Printer gray balance and density 
adjustment (Manual adjustment). (*1)
Enter the SIM67-25 mode, and select A4 
(11" x 8.5") paper. (Automatic selection.)
Press [EXECUTE] key.
(The adjustment pattern is printed.)
Select a target adjustment density level with the 
scroll key.
Enter the adjustment value with 10-key.
Press [EXECUTE] key.
(The adjustment pattern is printed.)
Are the gray balance 
and density at the sati-
sfactory level?
Cancel the SIM67-25 mode.
End
Check the gray balance and density in the gray
balance check pattern.
*1:
If satisfactory gray balance and density are not 
obtained with the adjustment, check the print
engine for any problems.
YES
NO
Are the gray balance and 
density at the satisfactory
level?
Use SIM64-5 to print the self print
check pattern, and check the printer gray balance and density.
Refer to the printed adjustment check pattern.
Check the self print check pattern to check the printer gray balance and 
density adjustment.
