General information 1-11 5058-030 Go Back Previous Next Media guidelines The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating new paper stock. •Weight—The printer can automatically feed paper weights from 60 to 300 g/m2 (16 to 80 lb bond) grain long. Paper lighter than 60 g/m2 (16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75 g/m2 (20 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend 90 g/m2 (24 lb) or heavier paper. Notes: –The duplex unit supports only 60–169 g/m2 (16–32 lb bond) paper weights. –The multipurpose feeder supports 60–300 g/m2 (16–80 lb bond) paper. •Curl—Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding problems. •Smoothness—Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield points; however, smoothness between 150 and 200 Sheffield points produces the best print quality. •Moisture content—The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly. Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that can degrade its performance.

1-12 Service Manual 5058-030 Go Back Previous Next Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. Extend the time several days if the storage or transportation environment is very different from the printer environment. Thick paper may also require a longer conditioning period. •Grain direction—Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of the paper, or grain short, running the width of the paper. For 60 to 135 g/m 2 (16 to 36 lb bond) paper, grain long paper is recommended. For papers heavier than 135 g/m2, grain short 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. Unacceptable paper The following paper types are not recommended for use with the printer: •Chemically treated papers used to make copies without carbon paper, also known as carbonless papers, carbonless copy paper (CCP), or no carbon required (NCR) paper •Preprinted papers with chemicals that may contaminate the printer •Preprinted papers that can be affected by the temperature in the printer fuser •Preprinted papers that require a registration (the precise print location on the page) greater than ±2.3 mm (±0.9 in.), such as optical character recognition (OCR) forms. In some cases, registration can be adjusted with a software application to successfully print on these forms. •Coated papers (erasable bond), synthetic papers, thermal papers •Rough-edged, rough or heavily textured surface papers, or curled papers •Recycled paper that fail EN12281:2002 (European) •Paper weighing less than 60 g/m2 (16 lb) •Multiple-part forms or documents Selecting paper Using appropriate paper prevents jams and helps ensure trouble-free printing. To help avoid jams and poor print quality: •Always use new, undamaged paper. •Before loading paper, know the recommended print 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 source; 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 190°C (374°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 190°C (374°F) without melting or releasing hazardous emissions.
General information 1-13 5058-030 Go Back Previous Next Using recycled paper and other office papers As an environmentally conscientious company, Lexmark supports the use of recycled paper produced specifically for use in printhead LED (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) •Surface roughness (measured in Sheffield units, impacts print clarity and how well toner fuses to the paper) •Surface friction (determines how easily sheets can be separated) •Grain and formation (impacts curling, which also influences the mechanics of how the paper behaves as it moves through the printer) •Brightness and texture (look and feel) Recycled papers are better than ever; however, the amount of recycled content in a paper affects the degree of control over foreign matter. And while recycled papers are one good path to printing in an environmentally responsible manner, they are not perfect. The energy required to de-ink and deal with additives such as colorants and “glue” often generates more carbon emissions than does normal paper production. However, using recycled papers enables better resource management overall. Lexmark concerns itself with the responsible use of paper in general based on life cycle assessments of its products. To gain a better understanding of the impact of printers on the environment, the company commissioned a number of life cycle assessments and found that paper was identified as the primary contributor (up to 80%) of carbon emissions caused throughout the entire life of a device (from design to end-of-life). This is due to the energy-intensive manufacturing processes required to make paper. Thus, Lexmark seeks to educate customers and partners on minimizing the impact of paper. Using recycled paper is one way. Eliminating excessive and unnecessary paper consumption is another. Lexmark is well- equipped to help customers minimize printing and copying waste. In addition, the company encourages purchasing paper from suppliers who demonstrate their commitment to sustainable forestry practices. Lexmark does not endorse specific suppliers, although a converter’s product list for special applications is maintained. However, the following paper choice guidelines will help alleviate the environmental impact of printing: 1.Minimize paper consumption. 2.Be selective about the origin of wood fiber. Buy from suppliers who carry certifications such as the Forestry Stewardship Council (FSC) or The Program for the Endorsement of Forest Certification (PEFC). These certifications guarantee that the paper manufacturer uses wood pulp from forestry operators that employ environmentally and socially responsible forest management and restoration practices. 3.Choose the most appropriate paper for printing needs: normal 75 or 80 g/m2 certified paper, lower weight paper, or recycled paper. 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%. Most label manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between 40 and 60%. •Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
