CAUTION: If your labels are less than the full width of the print head, the outside
edge will eventually wear out a small portion of the print head, resulting in an area
that will not print. Special care must be taken if you plan to use multiple widths of
labels, since the damaged portion of the print head caused from edge wear on a
more narrow label may affect the printing on a wider label. We suggest you plan your
print formats carefully to avoid using the area of possible damage on the print head
when using a wider label. The small area of damage will have no effect on printing
with the undamaged part of the print head.
Damage from a label edge is physical damage and is unavoidable. It is not covered
by warranty. It is possible to delay such damage by always ensuring that the ribbon
used is wider than the label stock. This will help to protect the print head from label
edge damage.
