Paper and specialty media guide 68 For 60-90‑g/m2 (16-24‑lb) bond paper, grain long paper is recommended. Fiber content Most high‑quality xerographic paper is made from 100% chemically treated pulped wood. This content provides the paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing fibers such as cotton can negatively affect paper handling. Selecting paper Using the appropriate paper prevents jams and helps ensure trouble‑free printing. To help avoid paper jams and poor print quality: • Always use new, undamaged paper. • Before loading paper, know the recommended printable side of the paper. This information is usually indicated on the paper package. • Do not use paper that has been cut or trimmed by hand. • Do not mix paper sizes, types, or weights in the same tray; mixing results in jams. • Do not use coated papers unless they are specifically designed for electrophotographic printing. Selecting preprinted forms and letterhead Use these guidelines when selecting preprinted forms and letterhead: • Use grain long for 60 to 90 g/m2 (16 to 24 lb) weight paper. • Use only forms and letterhead printed using an offset lithographic or engraved printing process. • Avoid papers with rough or heavily textured surfaces. Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. Use inks that are not affected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements; latex inks might not. When in doubt, contact the paper supplier. Preprinted papers such as letterhead must be able to withstand temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. Using recycled paper and other office papers As an environmentally conscientious company, Lexmark supports the use of recycled paper produced specifically for use in laser (electrophotographic) printers. While no blanket statement can be made that all recycled paper will feed well, Lexmark consistently tests papers that represent recycled cut size copier papers available on the global market. This scientific testing is conducted with rigor and discipline. Many factors are taken into consideration both separately and as a whole, including the following: • Amount of post-consumer waste (Lexmark tests up to 100% post-consumer waste content.) • Temperature and humidity conditions (Testing chambers simulate climates from all over the world.) • Moisture content (Business papers should have low moisture: 4-5%.) • Bending resistance and proper stiffness means optimum feeding through the printer. • Thickness (impacts how much can be loaded into a tray)
