Manual Adjustment: Reducing Horizontal Bands (Feed Correction Function)
Perform corrections to make the band-shaped "stripes" on the printed surface less noticeable.
The band-shaped "stripes" are called "horizontal bands" or "banding." Horizontal bands are caused by the
subtle changes in the movement distance that occur when feeding the media depending on the media's
thickness and the temperature of the dryer. We recommend that you make corrections to match the media
you are using and the set temperature of the dryer.
First, print a test pattern, and then determine and enter the correction value. After entering the correc-
tion value, print a test pattern again and check the correction results. Repeat the process of printing a
test pattern and entering a correction value several times to find the optimal correction value.
Procedure
1.
Load the media.

The current correction value (A) is that of the figure indicated by " ." Select the value to make
the gap (B) and overlap (C) between the upper/lower squares smallest. In the case of the following
figure, select "−0.40" (D). When you cannot choose between two sequential numbers, specify a val-
ue that is between them.
• If the test pattern is difficult to see, tap or next to [Media Feed] to move the media to a
position where it is easier to see.
