Gap Windowing
This feature compensates for any early falling edges or spurious peaks and
troughs that may appear within the gap length in media. These edges or
peaks and troughs can cause unreliable detection of the leading edge of the
next label (top-of-form). Use Gap Windowing to resolve the following
problems:
•
Loss of one or more complete (serialized) labels.
•
Start of an image printed in the middle of a gap, especially with fanfold,
perforated media.
•
Top part of an image lost when printing in head-first orientation.
The options for Gap Windowing are Disable and Enable:
•
Disable. When the leading edge of a gap is detected, the printer
continuously looks for the leading edge of the next label and uses it as the
TOF position. Perforations or unusual media discrepancies within the gap
can cause inaccurate TOF detection.
