3. With the front cover of the machine open (cover open/close
switch OFF), turn on the power.
4. Enter the SIM44-13 mode.
5. Close the front cover of the machine.
6. Press the [EXECUTE] key.
Adjustment is performed automatically. After completion of
adjustment, the result is displayed and the [EXECUTE] key
display returns to the original state.
7. Remove the color image density sensor adjustment jig.
(Set items)
If the adjustment is not completed normally, "ERROR" is displayed.
In case of an error, the contents of the adjustment are not revised.
(Display items)
When the value exceeds the detection range, "-" is displayed.
∗
In case of an error in the above operation, "ERROR" is
displayed and the color balance adjustment data (half-tone
initial data) are not stored.

Purpose Setting
Function
(Purpose) Used to store color balance adjustment data. (Half
tone image correction initial setting) (After execution
of color balance adjustment with SIM 46-21, this
simulation must be executed.)
Section Picture quality
Operation/
Procedure 1. Press the [EXECUTE] key, and it is highlighted
and the operation of color balance adjustment
data (half-tone correction initial data) storing is
started.
After completion of the execution, the
[EXECUTE] key returns to the normal display
