Table 12. General Symptom List
1. In the MEDIA CONTROL menu, set Clip Page to Disable.
2. Make sure the Label Length value matches the actual
physical length of the label installed.
3. In the QUICK SETUP or MEDIA CONTROL menu, set Ver
Image Shift to a (–) negative value to bring the image
closer to the leading edge of the label or to a (+) positive
value to move the image further down the label away from
the leading edge.
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.
4. In the CALIBRATE CTRL menu, set Gap Windowing to
Enable.
5. 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 gap has
caused the media sensor to detect this as the leading edge
(TOF) of the new label or end of label (EOF), or both.
