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.")
→User's Guide
•
Auto(OtherPaper)
Use this mode with paper not in the Paper Reference Guide, or if
Auto(GenuinePpr)
does not eliminate band-
ing.
(See "Types of Paper.")
→User's Guide
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.")
→User's Guide
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)
.
(See "Selecting a Feed Amount Adjustment Method.")
→P.87
•
If additional fine-tuning is necessary after
Auto(GenuinePpr)
and
Auto(OtherPaper)
, execute
Adj. Fine Feed
.
(See "Fine-Tuning the Paper Feed Amount.")
→User's Guide
•
Use
Adjust Length
to ensure that lines in CAD drawings are printed at exactly the right length.
(See "Adjusting Line Length.")
→User's Guide
•
This may take some time, depending on the type of paper.
