Gamma balance adjustment (Black Mode)
The gamma balance is adjusted by adjusting the density at the Black Mode. The adjustment is
performed by selecting its density area from the following: low density, medium density, and high
density.
When “Black” (600 dpi) is set for the color mode and “Auto” is selected for the halftone setting,
the gamma balance can be adjusted in each area of Text, Graphics and Image.

Notes:
• Be sure that this adjustment be made after performing
P. 4-7 “4.3.1 Automatic gamma
adjustment”.
• Changing the adjustment setting influences the adjacent density area slightly.
E.g.: When the value of the medium density is larger, the adjacent areas in the low density
and high density range will become slightly darker.
