Hint for media advance correction value
Appropriate media advance correction value varies as the following conditions change.
Conditions
Hint
A p p r o p r i a t e m e d i a a d v a n c e
correction value varies with the
media conditions such as media
type or media width size.
In addition, it may also var y with production
tolerance even when the same type of media is used.
Therefore, the media advance correction value must
be set when the roll media is replaced. (
P.2-38
)
A p p r o p r i a t e m e d i a a d v a n c e
correction value may vary when
the length of the tension bar to be
set on the roll feed unit is changed.
For combinations of the same media type and media
width size, always use an appropriate media advance
correction value for the same tension bar length. The
appropriate media advance correction value tends to
become smaller as the tension bar becomes shorter.
A p p r o p r i a t e m e d i a a d v a n c e
correction value may vary when
winding conditions for the take-up
reel unit are changed.
The appropriate media advance correction value tends
to become smaller when media is taken up by the
tension bar that is set on the takeup side rather than
when media is taken up by slack winding without
using the take-up reel unit.
A p p r o p r i a t e m e d i a a d v a n c e
correction value varies when print
mode is changed.
Appropriate media advance correction value differs with
the number of paths of the print mode. The same media
advance correction value can be used for the same
number of paths even in different print mode. (
P.4-2
)
A p p r o p r i a t e m e d i a a d v a n c e
correction value differs between
print heads of each color.
It is recommended that you usually set the average
of media advance correction values of all colors.
Better result can be obtained in some cases if you set
a media advance correction value considering the
importance of color according to the print data.
A p p r o p r i a t e m e d i a a d v a n c e
correction value differs on the right
and left sides of the media.
It is recommended that you usually set the average
of the right and left media advance correction values.
Better result can be obtained in some cases if you set
a media advance correction value considering the
importance of image position according to the print data.
When media is easy to adhere to
the paper guide like banner
It is recommended that you set the media advance
correction value by printing the media advance
correction pattern and then make adjustment while
changing the correction value during printing of an
actual image. (
P.3-8
)
Set the media advance correction value by printing the media advance correction
pattern and then change the correction value to an appropriate value while printing with
the actual print data to achieve better print quality. This method is effective for lengthy
printing in particular. (
