Note: Always use the rear exit when printing on card stock. To minimize curl, use the rear exit when
printing on labels.
When printing on labels:
• Set the Paper Type to Labels from the printer driver, the Local Printer Setup Utility, or
MarkVision.
• Do not load labels together with paper or transparencies in the same paper source.
• Do not use label sheets with a slick backing material.
• Do not print within 1 mm (0.040 in.) of the die cut.
• Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a
paper jam. Partial sheets will also contaminate your printer and your cartridge with adhesive,
and could void your printer and cartridge warranties.
• Use labels that can withstand temperatures of 205°C (401°F) without sealing, excessive
curling, wrinkling, or releasing hazardous emissions.
• Use labels that can withstand pressure of 25 pounds per square inch (psi).
• Do not print within 1 mm (0.040 in.) of the edge of the label, of the perforations, or between
die-cuts of the label.
• Do not use label sheets that have adhesive to the edge of the sheet. We recommend zone
coating of the adhesive at least 1 mm (0.040 in.) away from edges. Adhesive material will
contaminate your printer and could void your warranty.
• If zone coating of the adhesive is not possible, a 3 mm (0.125 in.) strip should be removed on
the leading and driver edge, and a non-oozing adhesive should be used.
• Remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling inside
the printer.
