Printing Tips for successful printing Storing paper Use the following guidelines to avoid paper feeding problems and uneven print quality. • Store paper in an environment where the temperature is approximately 21°C (70°F) and the relative humidity is 40%. • Store cartons of paper on a pallet or shelf rather than directly on the floor. • If you store individual packages of paper out of the original carton, make sure they rest on a flat surface so the edges do not buckle or curl.
Printing Avoiding jams You can avoid most paper jams by correctly loading paper and specialty media in the printer. See the following for loading instructions: • Loading 500-sheet trays • Loading the 2000-sheet tray • Loading the multipurpose feeder The following hints can help you avoid paper jams: • Use only recommended paper. Refer to the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.
3 Media specifications Media is paper, card stock, transparencies, labels, and envelopes. The last four are sometimes referred to as specialty media. The printer provides high quality printing on a variety of media. A number of things must be considered concerning media before printing. This chapter provides information to help make media selections and how to care for media. Media guidelines Selecting the appropriate media for the printer helps avoid printing problems.
Media specifications Weight The printer can automatically feed paper weights from 60 to 176 g/m2 (16 to 47 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 90 g/m2 (24 lb bond) grain long paper. To use paper narrower than 182 x 257 mm (7.2 x 10.1 in.), it is recommended that the weight be greater than or equal to 90 g/m2 (24 lb bond). Curl Curl is the tendency of media to curve at its edges.
Media specifications Unacceptable paper The following papers 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
Media specifications • Store cartons of paper on a pallet or shelf rather than directly on the floor. • If you store individual packages of paper 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 paper packages. • Store paper in its original wrapper until you load it into the printer.
Media specifications Selecting transparencies The printer can print directly on transparencies designed for use in laser printers. Print quality and durability depend on the transparency used. Always print samples on the transparencies being considered for use before buying large quantities. Lexmark recommends Lexmark Part Number 12A8240 letter size transparency and Lexmark Part Number 12A8241 A4 size transparency. The Paper Type setting should be set to Transparency to help prevent jams.
Media specifications Labels The printer can print on many labels designed for use with laser printers. These labels are supplied in letter size, A4 size, and legal size sheets. Label adhesives, face sheet (printable stock), and topcoats must be able to withstand temperatures of 230°C (446°F) and pressure of 25 pounds per square inch (psi). Try a sample of any labels considered for use with the printer before purchasing a large quantity.
Media specifications Card stock Card stock is single ply, and has a large array of properties, such as the moisture content, thickness, and texture, that can significantly affect print quality. For more information on the preferred weight for the grain direction of media, see Identifying media sources and specifications. Try a sample of any card stock considered for use with the printer before purchasing a large quantity.
