• 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 postage stamps attached
- 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 the 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.
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.
