– 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 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 two‑sided labels are not supported.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide available at
http://support.lexmark.com.
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 230°C (446°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 toner cartridge
warranties.
• Do not use labels with exposed adhesive.
• Do not print within 1 mm (0.04 inches) of the edge of the label, of the perforations, or between die‑cuts of the
label.
• Make sure the adhesive backing does not reach to the edge of the sheet. Zone coating of the adhesive should be
at least 1 mm (0.04 inches) away from edges. Adhesive material contaminates the printer and could void the
warranty.
• If zone coating of the adhesive is not possible, then remove a 2‑mm (0.06‑inches) strip on the leading and driver
edge, and use a non‑oozing adhesive.
• Portrait orientation is recommended, 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.
