– The labels can withstand temperatures up to 240°C (464°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 inch) 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 inch) away from edges. Adhesive material contaminates the printer and could void the warranty.

Tips on using envelopes

Print samples on the envelopes being considered for use before buying large quantities.

•For best performance, use envelopes made from 90‑g/m2 (24‑lb bond) paper or 25% cotton. All‑cotton envelopes must not exceed 75‑g/m2 (20‑lb bond) weight.

•Use only new envelopes from undamaged packages.

•To optimize performance and minimize jams, do not use envelopes that:

–Have excessive curl or twist

–Are stuck together or damaged in any way

–Have windows, holes, perforations, cutouts, or embossing

–Have metal clasps, string ties, or folding bars

–Have an interlocking design

–Have rough, cockle, or laid finishes

•Adjust the width guides to fit the width of the envelopes.
