Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal envelopes.
Using labels
Print samples on the labels being considered for use before buying large quantities.
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:
• From Print Properties or the printer control panel, set the Paper type to Labels.
• Do not load labels together with paper or transparencies in the same source; mixing media can cause feeding
problems.
• Use only letter-, A4-, and legal-size label sheets.
• Use labels designed specifically for laser printers, except vinyl labels. Check with the manufacturer or vendor to
verify that label adhesives, face sheet (printable stock), and topcoats can withstand temperatures up to 180°C
(356°F) and pressure up to 30 psi without delaminating, oozing around the edges, or releasing hazardous fumes.
Do not use vinyl labels.
• Do not use labels with slick backing material.
