Page 47: General Information
General information The Lexmark MX71x and MX81x are network‑capable, multi‑function laser printers that print monochrome print jobs. The operator panel is touch‑sensitive and lets the user adjust the viewing angle. All information in this service manual pertains to all models unless explicitly noted.
Page 48: Selecting Paper
7463 Weight The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m (16–47‑lb) grain long paper. The 2100‑sheet tray can automatically feed paper weights up to 60–135 g/m (16–36‑lb) grain long paper. Paper lighter than 60 g/m (16 lb) might not be stiff enough to feed properly, and may cause jams.
Page 49: Selecting Preprinted Forms And Letterhead
(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.
Page 50 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).
Page 51: Using Specialty Media
7463 Using specialty media Tips on using card stock Card stock is heavy, single‑ply specialty media. Many of its variable characteristics, such as moisture content, thickness, and texture, can significantly affect print quality. • From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the card stock loaded in the tray.
Page 52: Tips On Using Letterhead
7463 • For more information on label printing, characteristics, and design, see the Card Stock & Label Guide at http://support.lexmark.com. • Use labels designed specifically for laser printers. • Do not use labels with slick backing material. • Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and toner cartridge warranties.
Page 53: Supported Paper Sizes, Types, And Weights
7463 Supported paper sizes, types, and weights The following tables provide information on standard and optional paper sources and the sizes, types, and weights of paper they support. Note: For an unlisted paper size, select the closest larger listed size. Paper sizes supported by the printer Note: When printing on paper less than 210 mm (8.3 inches) wide, the printer may print at a reduced speed after a period of time to ensure the best print performance.

7463 • Hard disk memory—The printer hard disk is designed for printer-specific functionality and cannot be used for the long‑term storage of data that is not print-related. The hard disk can retain buffered user data from complex print jobs, form data, and font data. To erase volatile memory, turn off the printer.
Page 59: Diagnostic Information
7463 Diagnostic information CAUTION—SHOCK HAZARD: Remove the power cord from the electrical outlet before you connect or disconnect any cable or electronic card or assembly for personal safety and to prevent damage to the printer. Disconnect any connections between the printer and PCs/peripherals. CAUTION—POTENTIAL INJURY: The printer weight is greater than 18 kg (40 lb) and requires two or more trained personnel to lift it safely.
