Paper and specialty media guide 43 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. Unacceptable paper examples Test results indicate that the following paper types are at risk for use with laser printers: • Chemically treated papers used to make copies without carbon paper, also known as carbonless papers • 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 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 papers that fail EN12281:2002 (European testing) • Paper weighing less than 60 g/m2 (16 lb) • Multiple part forms or documents For more information about Lexmark, visit www.lexmark.com.

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.
