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
Notes:
• Single‑sided paper labels designed for laser/LED printers are supported for occasional use.
• It is recommended to print no more than 20 pages of paper labels a month.
• Vinyl, pharmacy, and dual‑sided labels are not supported.
For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on
the Lexmark Web site at

When printing on labels:
• Use labels designed specifically for laser/LED printers. Check with the manufacturer or vendor to verify that:
– The labels can withstand temperatures up to 210°C (410°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions.
Note: Labels can be printed at a higher fusing temperature up to 220°C (428°F) if Label Weight is set to
Heavy. Select this setting using the Embedded Web Server, or from the printer control panel Paper menu.
– 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 cartridge warranties.
• Do not use labels with exposed adhesive.
