– 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: Paper labels are supported. Other media such as vinyl may show print quality defects in some environments,
and prolonged vinyl label usage may reduce fuser life.
For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on
the Lexmark Web site at http://support.lexmark.com.
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 190°C (374°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions.
– 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.
• If zone coating of the adhesive is not possible, remove a 1.6 mm (0.06 in.) strip on the leading and driver edge, and
use a non‑oozing adhesive.
• Portrait orientation works best, especially when printing bar codes.
Tips on using card stock
Card stock is heavy, single‑ply specialty media. Many of its variable characteristics, such as moisture content, thickness,
and texture, can significantly impact print quality. Print samples on the card stock being considered for use before
buying large quantities.
• From the Paper menu, set the Paper Type to Card Stock.
• Select the appropriate Paper Texture setting.
• Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams or
other paper handling problems.
• Check with the manufacturer or vendor to ensure the card stock can withstand temperatures up to 220°C (446°F)
without releasing hazardous emissions.
• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi‑liquid and volatile components into the printer.
• Use grain short card stock when possible.
