MX-3114N ADJUSTMENTS AND SETTINGS 5 – 42
1) Enter the SIM46-21 mode.
2) Press [EXECUTE] key. (A4/11" x 8.5" or A3/11" x 17" 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.
If the color balance of each patch of the process black (CMY
mixed color) is slightly shifted to Magenta, it means that the
adjustment is proper. If the color balance of the adjustment
pattern printed in this mode is slightly shifted to Magenta, it is
converted into the natural gray color balance by the color cor-
rection table in an actual copy mode. (When the color balance
target is DEF 1.)
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 (1 - 999). When
SIM 46-24 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 - Q (MAX) to a same level collectively.
Then, adjust each patch density individually. This is an efficient
way of adjustment.
Referring to the black/gray patches, adjust so that each pro-
cess (CMY) black/gray patch color balance of A - Q (MAX)
approaches the black/gray patch level as far as possible.
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.
