Recommendations for using labels
Labels are a type of multiple-layer media that typically consists of a face sheet (the printable surface), pressure-
sensitive adhesive, and a liner (a carrier sheet coated with a release agent). Labels to be used in your HP LaserJet
printer must be
specically designed for laser printers. If labels other than those compatible with laser printers
are used, a signicant risk exists for labels peeling or for adhesive contamination that can severely damage your
printer. All materials in laser label stock must be compatible with the heat and pressure of the fusing process,
and must not melt or release undesirable emissions when heated to 205°C (401°F) for 0.1 second (0.2 second
for HP color LaserJet printers).
CAUTION:
● The liner or release layer should not be exposed. Open spaces and gaps might trap toner and prevent it
from fusing properly.
● Not all HP color LaserJet printers support printing on labels from all trays. Please see the support
documentation that came with your product to determine if your product supports labels.
Guidelines for using labels
Follow these guidelines for using labels to ensure optimal performance.
The label properties and specications provided in this table generally apply to all HP LaserJet printers. See the
support documentation that came with your printer for product-specic information.

Adhesives Adhesives must not be on any external surfaces of the label before,
during, or after printing. Label construction, adhesive release
strength, and appropriate die-cutting must prevent labels from
peeling o during printing.
Dierent adhesives can provide removable, permanent, or semi-
permanent xing of the face sheet onto the item being labeled.
Generally, acrylic-based adhesives are preferred for laser printing
because they can be applied in very thin layers to prevent oozing
and contamination, and can be made compatible with the heat and
pressure of fusing.
Improved processes are being developed to minimize adhesive
contamination, such as zone coating or stripped matrix. Zone
coating recesses the adhesive around the border of a die-cut, and
stripped matrix prevents adhesive from oozing between the die-cut
labels. The adhesive and liner must provide adequate release
strength so that labels will not peel o during printing.
Caliper The caliper must not exceed 0.23 mm (9.0 mils).
