Paper

For the best print quality, use 75 g/m2 (20 lb) xerographic, grain long paper. Try a sample of any paper you are considering using with the MFP before buying large quantities,.

When loading paper, note the recommended print side on the paper package, and load paper accordingly. See Loading standard trays and optional trays, Loading the multipurpose feeder, or Loading the 2000-sheet drawer for detailed tray-loading instructions.

Paper characteristics

The following paper characteristics affect print quality and reliability. We recommend that you follow these guidelines when evaluating new paper stock.

For detailed information, see the Card Stock & Label Guide located on the Lexmark Web site at www.lexmark.com.

The laser printing process heats paper to high temperatures of 230°C (446°F). For Magnetic Ink Character Recognition (MICR) applications and for non-MICR applications, use only paper able to withstand these temperatures without discoloring, bleeding, or releasing hazardous emissions. Check with the manufacturer or vendor to determine whether the paper you have chosen is acceptable for laser printers.

Weight

The MFP can automatically feed paper weights from 60 to 176 g/m2 (16 to 47 lb bond) grain long in the integrated and optional 500-sheet trays and paper weights from 60 to 135 g/m2 (16 to 36 lb bond) grain long in the multipurpose feeder and optional 250-sheet trays. 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. When using paper narrower than 182 x 257 mm (7.2 x 10.1 in.), make sure the weight is greater than or equal to 90 g/m2 (24 lb bond).

Unacceptable paper

The following papers are not recommended for use with the MFP:
