Paper and specialty media guide 49 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 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. • If zone coating of the adhesive is not possible, then remove a 2‑mm (0.06‑inch) strip on the leading and driver edge, and then use a non‑oozing adhesive. • Portrait orientation is recommended, especially when printing bar codes. Tips on using card stock Card 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 before buying large quantities. When printing on card stock: • Make sure the Paper Type is Card Stock. • Select the appropriate Paper Texture setting. • Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams or other paper handling problems. • Check with the manufacturer or vendor to ensure that the card stock can withstand temperatures up to 240°C (464°F) without releasing hazardous emissions. • Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting introduces semi‑liquid and volatile components into the printer. • Use grain short card stock when possible. Storing paper Use these paper storage guidelines to help avoid jams and uneven print quality: • For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent. Most label manufacturers recommend printing in a temperature range of 18-24°C (65-75°F) with relative humidity between 40 and 60 percent. • Store paper in cartons, on a pallet or shelf, rather than on the floor. • Store individual packages on a flat surface.
