Symptom
The cutting position is
shifted randomly.

the roll media, the X

The cutting distance of
the X direction (feeding
direction) is a little
bit short or long and
it occurred when it is
cutting the long distance.

Verification item
Confirm the media is not skewing
while cutting the media.
The heavy roll media can not feed
from the media roll by high speed
cutting. Therefore media needs to
feed out enough length from the
media roll before cutting.
The feeding length depends on the
thickness of media. Therefore it must
adjust the distance adjustment for the
X direction.
When weak adhesive strength media is
used for the wider and longer cutting, the
surface of media peels off from the base
media by the weight of media while the
media is feeding, and then the media will
skew.
Use the media of strong adhesive
strength.
Set the auto pre-feed setting in the
MEDIA SETTING menu.
PAUSE/MENU --> 4 MEDIA --> 2 AUTO
PRE FEED --> Set it to ON, and then set
the feed length which you want to cut the
length.
Adjust the X distance adjustment in the
DISTANCE ADJUST of condition menu.
COND/TEST --> 1 DISTANCE ADJUST
--> Set it ON to the corresponding
condition No. --> 3 X=x.xxx% --> Set the
adjustment value.
For example:
The 5 mm is short when it cuts the 5 m.
Adjustment value is:
5 mm / 5000 mm x 100 = 0.1%
Set the +0.1% for the X distance
adjustment.
