• 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/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
Note: This printer is intended for occasional paper label printing only.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide at
http://support.lexmark.com.
• 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.
