Using Print Materials Using Your Printer To minimize jams, do not use envelopes that: • Have excessive curl or twist • Are stuck together • Are damaged in any way • Contain windows, holes, perforations, cutouts, or embossing • Use metal clasps, string ties, or metal 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 nicked edges or bent corners • Have rough, cockle, or laid finishes Label Guidelines The printer can print on many labels designed for use with laser printers. These labels are supplied in letter-size and A4-size sheets. When printing on labels, be sure to select Labels in the PAPER TYPE menu in the PAPER MENU. Do not load labels together with paper or transparencies in the same paper tray. Combining print materials can cause feeding problems. Do not load partial sheets with areas exposed by missing labels. This can cause labels to peel off during printing, resulting in a paper jam. Partial sheets will also contaminate your printer and your cartridge with adhesive, and could void your printer and cartridge warranties. Labels are one of the most difficult print materials for laser printers. A special fuser cleaner should be used for label application to optimize feed reliability. See "Ordering a Label Fuser Cleaner" on page 248 for more information. Using Print Materials 131
