When printing on envelopes:
• Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the
envelopes can withstand temperatures up to 210°C (410°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
• For the best performance, use envelopes made from 90 g/m
2
(24 lb bond) paper. Use up to 105 g/m
2
(28 lb bond)
weight for envelopes as long as the cotton content is 25% or less. All-cotton envelopes must not exceed
90 g/m
2
(24 lb bond) weight.
• Use only new envelopes.
• 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 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 www.lexmark.com/publications.
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 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.
• Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label.
• Be sure adhesive backing does not reach to the sheet edge. Zone coating of the adhesive at least 1 mm (0.04 in.)
away from edges is recommended. Adhesive material contaminates the printer and could void the warranty.
