Automatic Banding Adjustment (Adj. Quality)
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.
•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 (6.1.1).")
Important
•  Adjustment is not possible with Auto(GenuinePpr) and Auto(OtherPaper) when using highly transparent media.
In this case, use Manual adjustment.
 (See "Manual Banding Adjustment (Adj. Quality) (7.3.4).")
Note
•  We recommend executing the adjustment if you have changed the paper type or paper size.
•  Always check the Adj. Priority values before using Auto(GenuinePpr) or Auto(OtherPaper).
