Purpose
:
Adjustment
Function (Purpose)
Used to execute the high density process
control forcibly.
Section
Process
Operation/Procedure
When [OK]/[START] key is pressed, the adjustment is exe-
cuted automatically.
After completion of the adjustment, the adjustment result is
displayed. (Refer to the table below.)
If the adjustment is not executed normally, "ERROR" is dis-
played.
