5.4 Labels
A label consists of a face sheet, an adhesive sheet, and a carrier sheet.
The face sheet (or printing surface) is usually composed of photocopying
paper and should meet the same specifications for paper as described in
Table 5–2. The carrier sheet and adhesive used for the labels must also be
able to meet the heat tolerance specification of 200°C (392°F) for at least
0.1 second.
CAUTION:
Exposed adhesive on labels can damage the printer. To test for
exposed adhesive, press a plain piece of paper on top of the sheet of labels.
If the paper sticks to the labels, you should not use those labels.
Figure 5–1 shows the types of labels that are unacceptable.
