Paper
For the best print quality, use 75 g/m
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.

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/m
integrated and optional 500-sheet trays and paper weights from 60 to 135 g/m
the multipurpose feeder and optional 250-sheet trays. Paper lighter than 60 g/m
enough to feed properly, causing jams. For best performance, use 75 g/m
using paper narrower than 182 x 257 mm (7.2 x 10.1 in.), make sure the weight is greater than or equal to
2
90 g/m (24 lb bond).
Unacceptable paper
The following papers are not recommended for use with the MFP:
•
Some 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 (see the Card Stock & Label
Guide located on the Lexmark Web site at www.lexmark.com for supported chemically treated papers)
•
Preprinted papers with chemicals that may contaminate the MFP
•
Preprinted papers that can be affected by the temperature in the MFP fuser
•
Preprinted papers that require a registration (the precise print location on the page) greater than ±0.09 in.,
such as optical character recognition (OCR) forms
•
In some cases, you can adjust registration with your 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 containing more than 25% post-consumer waste that do not meet DIN 19 309
•
Recycled paper having a weight less than 60 g/m
•
