Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
•
Use envelopes designed specifically for laser/LED printers. Check with the manufacturer or vendor to ensure
that the envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling
excessively, or releasing hazardous emissions.
•
For best performance, use envelopes made from 90 g/m
2
(24 lb bond) paper or 25% cotton. All
‑
cotton
envelopes must not exceed 70 g/m
2
(20 lb bond) weight.
•
Use only new envelopes from undamaged packages.
•
To optimize performance and minimize jams, do not use envelopes that:
–
Have excessive curl or twist
–
Are stuck together or damaged in any way
–
Have windows, holes, perforations, cutouts, or embossing
–
Have metal clasps, string ties, or folding bars
–
Have an interlocking design
–
Have postage stamps attached
–
Have any exposed adhesive when the flap is in the sealed or closed position
–
Have bent corners
–
Have rough, cockle, or laid finishes
•
Adjust the width guides to fit the width of the envelopes.
Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal
envelopes.
Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note: Use only paper label sheets. Vinyl, pharmacy, and two
‑
sided labels are not supported.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide available
at http://support.lexmark.com .
When printing on labels:
•
Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
–
The labels can withstand temperatures up to 230°C (446°F) without sealing, excessive curling, wrinkling,
or releasing hazardous emissions.
–
Label adhesives, face sheet (printable stock), and topcoats can withstand up to 25
‑
psi (172
‑
kPa) pressure
without delaminating, oozing around the edges, or releasing hazardous fumes.
•
Do not use labels with slick backing material.
•
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial
sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and toner
cartridge warranties.
•
Do not use labels with exposed adhesive.
•
Do not print within 1 mm (0.04 inches) of the edge of the label, of the perforations, or between die
‑
cuts of
the label.
