Print media Card stock Card stock is single ply, and has a large array of properties, such as the orientation of paper fibers and texture, that can significantly affect the print quality. You may only print card stock from the multipurpose feeder. Card stock must always exit to the rear output bin. For detailed information on card stock printing, characteristics, and design, refer to the Card Stock & Label Guide available on Lexmark's Web site at www.lexmark.com/publications. • Do not use card stock that is perforated or creased. Preprinting, perforation, and creasing can significantly affect the print quality and cause media handling or jamming problems. • Avoid using card stock that may release hazardous emissions when heated. • Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting introduces semi-liquid and volatile components into the printer. • We recommend the use of grain short card stock. Storing print media Use the following guidelines for proper print media storage. These help avoid paper feeding problems and uneven print quality: • For best results, store print media in an environment where the temperature is approximately 21°C (70°F) and the relative humidity is 40%. • Store cartons of print media on a pallet or shelf, rather than directly on the floor. • If you store individual packages of print media out of the original carton, make sure they rest on a flat surface so the edges do not buckle or curl. • Do not place anything on top of the print media packages. • Keep paper sealed in its original packaging until ready to use.
