Adjustments for Better Print Quality

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.
(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.")
Note
• Always check the Adj. Priority values before using Auto(GenuinePpr) or Auto(OtherPaper).
(See "Selecting a Feed Amount Adjustment Method (Feed Priority).")
• 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).")
• If additional fine-tuning is necessary after Auto(GenuinePpr) and Auto(OtherPaper), execute Adj. Fine
6
Feed.
(See "Fine-Tuning the Paper Feed Amount (Adj. Fine Feed).")
• Use Adjust Length to ensure that lines in CAD drawings are printed at exactly the right length.
(See "Adjusting Line Length (Adjust Length).")
• This may take some time, depending on the type of paper.
• Use paper of the same type and size for adjustment as you will use for printing.
