Solution/Explanation
1. Make sure the Label Length value matches the actual
physical length of the label installed and the run on Auto
Calibrate (see page 72).
These symptoms could be caused by:
•
severely curled labels near the end of a media roll
•
the media sensor triggering off of a dark, preprinted image
on the label
•
multiple gaps within the physical label.
2. In the MEDIA CONTROL menu, set Clip Page to Disable.
3. Run a Media Profile (see page 74).
4. If the Media Profile printout shows that preprinted images
or an RFID antenna tag has an amplitude approaching the
Gap/Mark Threshold level, position the lower media
sensor to avoid the image or increase the Threshold
Range percent value in the Calibrate CTRL menu. Run
Auto Calibrate again and Media Profile to verify there is an
improvement.
1. In the CALIBRATE CTRL menu, set Gap Windowing to
Enable.
2. Set Gap Length to equal the physical gap length of the
media installed. The range is 0.05 to 1.00 inches.
The likely cause of these symptoms is that Clip Page = Enable
and a cross-perforation, radical fold or flaw in the liner has
caused the media sensor to detect this as the leading edge
(TOF) of the new label or end of label (EOF), or both.
