– 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 labelsPrint 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, orreleasing hazardous emissions.– Label adhesives, face sheet (printable stock), and topcoats can withstand up to 25‑psi (172‑kPa) pressure withoutdelaminating, 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 sheetsalso contaminate the printer and the cartridge with adhesive, and could void the printer and toner cartridgewarranties.• 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 thelabel.• Make sure the adhesive backing does not reach to the edge of the sheet. Zone coating of the adhesive should beat least 1 mm (0.04 inches) away from edges. Adhesive material contaminates the printer and could void thewarranty.• If zone coating of the adhesive is not possible, then remove a 2‑mm (0.06‑inches) strip on the leading and driveredge, and use a non‑oozing adhesive.• Portrait orientation is recommended, especially when printing bar codes.Tips on using card stockCard stock is heavy, single‑ply specialty media. Many of its variable characteristics, such as moisture content, thickness,and texture, can significantly impact print quality. Print samples on the card stock being considered for use beforebuying large quantities.• From the Paper menu, set the Paper Type to Card Stock.• Select the appropriate Paper Texture setting.• Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams orother paper handling problems.• Check with the manufacturer or vendor to ensure the card stock can withstand temperatures up to 220°C (446°F)without releasing hazardous emissions.Paper and specialty media guide 71
