Automatic Banding Adjustment

Automatic Banding Adjustment
If printed images are affected by banding in different colors across the sheet, execute Adj. Quality for automatic
adjustment of the paper feed amount.
There are two modes of automatic adjustment to correct banding: Auto(GenuinePpr) and Auto(OtherPaper). In
either mode, the printer prints and reads a test pattern for automatic adjustment of the feed amount.
• Auto(GenuinePpr)
Use this mode with paper identified in the Paper Reference Guide.
(See "Types of Paper.")
Auto(OtherPaper)
•
Use this mode with paper not in the Paper Reference Guide, or if Auto(GenuinePpr) does not eliminate
banding.
(See "Types of Paper.")
•
Adjustment is not possible with Auto(GenuinePpr) and Auto(OtherPaper) when using highly transparent media.
In this case, use Manual adjustment.
Important
(See "Manual Banding Adjustment.")
•
We recommend executing the adjustment if you have changed the paper type or paper size.
•
Note
Always check the Adj. Priority values before using Auto(GenuinePpr) or Auto(OtherPaper).
(See "Selecting a Feed Amount Adjustment Method.")
•
If additional fine-tuning is necessary after Auto(GenuinePpr) and Auto(OtherPaper), execute Adj. Fine Feed.
(See "Fine-Tuning the Paper Feed Amount.")
•
Use Adjust Length to ensure that lines in CAD drawings are printed at exactly the right length.
(See "Adjusting Line Length.")
•
This may take some time, depending on the type of paper.
