Lexmark C950 manual Tips on using envelopes, Tips on using labels

Do not use labels with exposed adhesive.

•

– 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.

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/m2 (24 lb bond) paper or 25% cotton. All‑cotton envelopes must not exceed 70 g/m2 (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.
