Notes:
• When this adjustment was performed, perform "Automatic gamma adjustment (black) (05-
7165)" as well because the density reproduction level in the black mode will vary. In addition
to performing the code 05-7165, perform the code 05-7869 or 05-7871 individually because
the result of this adjustment will not be reflected to the color & black integrated pattern.
• After this adjustment, set "1" in 08-7625 so that the correction result of the Black Mode is not
reflected on "Automatic Calibration".
