•Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures of 230°C (446°F) without melting, discoloring, offsetting, or releasing hazardous emissions.

•To prevent print quality problems, avoid getting fingerprints on the transparencies.

•Before loading transparencies, fan the stack to prevent sheets from sticking together.

•We recommend Lexmark transparencies. For ordering information, see the Lexmark Web site at www.lexmark.com.

Tips on using envelopes

Print samples on the envelopes being considered for use before buying large quantities.

•Use envelopes designed specifically for laser 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.

Tips on using labels

Note: This printer is intended for occasional paper label printing only.

For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com/publications.

•Do not load labels together with paper or transparencies in the same source; mixing media can cause feeding problems.

•From the Paper menu, set the Paper Type to Labels.

•Do not use labels with slick backing material.

•Use labels that can withstand temperatures of 230°C (446°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions.

•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.
