C1760nw problem printing labels

TheKug,

Below are the label guidelines for using with the printer.

Labels

When selecting labels:

• Label adhesives, face sheet (printable stock), and topcoats must be able to withstand temperatures of 205 °C (401 °F) and pressure of 25 pounds per square inch (psi).
• Use labels that can be without sealing, excessive curling, wrinkling, or releasing hazardous emissions.
• Do not use label sheets with a slick backing material.

When printing on labels:

• Set the paper type to Label from the printer driver.
• Do not load labels together with paper in the same tray.
• Do not print within 1 mm (0.04 inches) of the die-cut.
• 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.
• Do not print a label through the printer more than once.
• Portrait orientation is preferred, especially when printing bar codes.
• Do not use labels that have exposed adhesive.
• Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam.
