Executing Auto Gradation Adjustment
The machine can automatically adjust gradation when the reproducibility of density or
color in copies and prints has deteriorated. The machine can adjust the gradation for
each screen type.
There are the following four types of screen.
z
Copy Job - Text
This screen compensates gradation when making copies of text and other
documents.
z
Copy Job - Photo
This screen compensates gradation when making copies of photos and other
documents.
z
Print Job - Text
This screen compensates gradation when printing text and other data.
z
Print Job - Photo
This screen compensates gradation when printing photos and other data.
Important •
As auto gradation adjustment uses Tray 5 (bypass), reset the tray to plain paper if the paper
type for the tray is set to any other paper type. For information about the setting procedure,
refer to "Paper Type" (P.260).
Note
•
We recommend executing auto gradation adjustment for all four of the screen types. When
the adjustment for one screen type is complete, specify the next screen type and repeat the
procedure.
•
If color shift is not compensated for despite the periodic execution of auto gradation
adjustment, contact our Customer Support Center.
•
The default copy settings of the System Administration mode change to the following when
gradation adjustment is executed.
Copy density = Normal or Auto (The default setting value of this feature returns to Normal
when it is Light to Dark, and returns to Auto when it is Auto.), Color Shift = Normal, Color
Saturation = Normal, Color Balance = 0, Sharpness = Normal
