Labels
When selecting labels, consider the following factors:
■ Adhesives: The adhesive material should be stable at 200°C (392°F), the printer’s maximum
temperature.
■ Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets
that have spaces between the labels, causing serious jams.
■ Curl: Before printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction.
■ Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. Never use
a sheet of labels that has already been sent through the printer.
Envelopes
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers but also within a box from the same manufacturer. Successful printing on envelopes
depends on the quality of the envelopes. When selecting envelopes, consider the following factors:
■
Weight: The weight of the envelope paper should not exceed 105 g/m
2
(28 lb), or jamming might
result.
■ Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl and
should not contain air. Envelopes that trap air may cause problems.
■ Condition: Make sure that the envelopes are not wrinkled, nicked, or otherwise damaged.
■ Sizes: From 90 x 160 mm (3.5 x 6.3 inches) to 178 x 254 mm (7 x 10 inches).
Store envelopes flat. If air is trapped in an envelope, creating an air bubble, the envelope might wrinkle
during printing.
Envelopes with double-side seams
An envelope with double-side-seam construction (vertical seams at both ends of the envelope rather
than diagonal seams) is more likely to wrinkle. Make sure the seam extends all the way to the corner of
the envelope as shown in top figure of the following illustration:
