Media guidelines
Additional information for printing on specialty media may be found in the Cardstock and Label Guide available at
http://support.lexmark.com.
Paper guidelines
Selecting the correct paper or specialty media reduces printing problems. For the best print quality, try a sample of the
paper or specialty media before buying large quantities.
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating
new paper stock.
Weight
The standard printer trays can automatically feed paper weights up to 90‑g/m2 (24‑lb) bond grain long paper. The
2
optional trays can automatically feed paper weights up to 120‑g/m
feeder can automatically feed paper weights up to 163‑g/m
60 g/m
bond grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 inches), it is recommended to use 90 g/m
(24 lb) or heavier paper.
Note: Two‑sided printing is supported only for 60–90‑g/m
2
(16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75‑g/m2 (20‑lb)

Page 26
7016
Curl
Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur after
the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid,
cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding
problems.
Smoothness
Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too
smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield points;
smoothness between 150–250 Sheffield points produces the best print quality.
Moisture content
The amount of moisture in paper affects both print quality and the ability of the printer to feed the paper correctly.
Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes that
can degrade its performance.
Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24–48
hours before printing. Extend the time to several days if the storage or transportation environment is very different
from the printer environment. Thick paper may also require a longer conditioning period.
Grain direction
Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of
the paper, or grain short, running the width of the paper.
2
For 60–90‑g/m
(16–24‑lb) bond paper, grain long paper is recommended.
Fiber content
Most high‑quality xerographic paper is made from 100% chemically treated pulped wood. This content provides the
paper with a high degree of stability resulting in fewer paper feeding problems and better print quality. Paper containing
fibers such as cotton can negatively affect paper handling.
Unacceptable paper
The following paper types 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 page) greater than ±2.4 mm
(±0.9 inch), such as optical character recognition (OCR) forms
In some cases, registration can be adjusted with a 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 that fail EN12281:2002 (European)
• Paper weighing less than 60 g/m
• Multiple‑part forms or documents

Selecting paper
Using the appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid paper jams and poor print quality:
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable side of the paper. This information is usually indicated on
the paper package.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, types, or weights in the same tray; mixing results in jams.
• Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
• Use grain long for 60 to 90 g/m
• Use only forms and letterhead printed using an offset lithographic or engraved printing process.
• Avoid papers with rough or heavily textured surfaces.
2
(16 to 24 lb) weight paper.
Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to withstand
temperatures up to 190°C (374°F) without melting or releasing hazardous emissions. Use inks that are not affected by
the resin in toner. Inks that are oxidation‑set or oil‑based generally meet these requirements; latex inks might not.
When in doubt, contact the paper supplier.
Preprinted papers such as letterhead must be able to withstand temperatures up to 190°C (374°F) without melting or
releasing hazardous emissions.
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent. Most
label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative humidity
between 40 and 60 percent.
• Store paper in cartons, on a pallet or shelf, rather than on the floor.
• Store individual packages on a flat surface.
• Do not store anything on top of individual paper packages.
• Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and wrapper
help keep the paper clean, dry, and flat.
Using recycled paper and other office papers
As an environmentally conscious company, Lexmark supports the use of recycled office paper produced specifically for
use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US government a study demonstrating
that recycled paper produced by major mills in the US fed as well as non-recycled paper. However, no blanket statement
can be made that all recycled paper will feed well.
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of test paper
from around the world, using chamber tests for different temperature and humidity conditions. Lexmark has found no

reason to discourage the use of today's recycled office papers, but generally the following property guidelines apply
to recycled paper.
• Low moisture content (4–5%)
• Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European)
Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and much
rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to work very
well in laser printers, despite surface texture. Before using these types of paper, consult your paper supplier.
• Suitable sheet-to-sheet coefficient of friction (0.4–0.6)
• Sufficient bending resistance in the direction of feed
2
Recycled paper, paper of lower weight (<60 g/m
that is cut grain-short for portrait (or short-edge) fed printers may have lower bending resistance than is required for
reliable paper feeding. Before using these types of paper for laser (electrophotographic) printing, consult your paper
supplier. Remember that these are general guidelines only and that paper meeting these guidelines may still cause
paper feeding problems in any laser printer (for example, if the paper curls excessively under normal printing
conditions).

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 impact print quality. Print samples on the card stock being considered for use before
buying large quantities.
• From the Paper menu, set the Paper Type to Card Stock.
• Select the appropriate Paper Texture setting.
• Be aware that preprinting, perforation, and creasing may significantly affect the print quality and cause jams or
other paper handling problems.
• Check with the manufacturer or vendor to ensure the card stock can withstand temperatures up to 220°C (446°F)
without releasing hazardous emissions.
• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer. Preprinting
introduces semi‑liquid and volatile components into the printer.
• Use grain short card stock when possible.
Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed specifically for laser/LED printers. Check with the manufacturer or vendor to ensure that
the envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
• For best performance, use envelopes made from 90 g/m
must not exceed 70 g/m

(20 lb bond) weight.
• Use only new envelopes from undamaged packages.
• To optimize performance and minimize jams, do not use envelopes that:
– Have excessive curl or twist
– Are stuck together or damaged in any way

– Have windows, holes, perforations, cutouts, or embossing
– Have metal clasps, string ties, or folding bars
– Have an interlocking design
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed or closed position
– Have bent corners
– Have rough, cockle, or laid finishes
• Adjust the width guides to fit the width of the envelopes.
Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal envelopes.
Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note: Use only paper label sheets. Vinyl, pharmacy, and two‑sided labels are not supported.
For more information on label printing, characteristics, and design, see the Card Stock & Label Guide available at
http://support.lexmark.com.
When printing on labels:
• Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that:
– The labels can withstand temperatures up to 230°C (446°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions.
– Label adhesives , face sheet (printable stock) , and topcoats can withstand up to 25‑psi (172‑kPa) pressure without
delaminating, oozing around the edges, or releasing hazardous fumes.
• 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.
• Do not use labels with exposed adhesive.
• Do not print within 1 mm (0.04 inches) of the edge of the label, of the perforations, or between die‑cuts of the
label.
• Make sure the adhesive backing does not reach to the edge of the sheet. Zone coating of the adhesive should be
at least 1 mm (0.04 inches) away from edges. Adhesive material contaminates the printer and could void the
warranty.
• If zone coating of the adhesive is not possible, then remove a 2‑mm (0.06‑inches) strip on the leading and driver
edge, and use a non‑oozing adhesive.
• Portrait orientation is recommended, especially when printing bar codes.
Tips on using letterhead
• Use letterhead designed specifically for laser printers.
• Print samples on the letterhead being considered for use before buying large quantities.
• Before loading letterhead, flex, fan, and straighten the stack to prevent sheets from sticking together.
• Page orientation is important when printing on letterhead.
General information

7016
Tips on using transparencies
• Print a test page on the transparencies being considered for use before buying large quantities.
• Feed transparencies from the standard tray, or the multipurpose feeder.
• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures
up to 185°C (365°F) without melting, discoloring, offsetting, or releasing hazardous emissions.
Note: If the transparency weight is set to Heavy and the transparency texture is set to Rough in the Paper menu,
then transparencies can be printed at a temperature up to 195°C (383°F).
• Avoid getting fingerprints on the transparencies to prevent print quality problems.
• Before loading transparencies, flex, fan, and straighten the stack to prevent sheets from sticking together.

Understanding jam messages and locations
7016
When a jam occurs, a message indicating the jam location and information to clear the jam appears on the printer
display. Open the doors, covers, and trays indicated on the display to remove the jam.
Notes:
• When Jam Assist is set to On, the printer automatically flushes blank pages or pages with partial prints to the
standard bin after a jammed page has been cleared. Check your printed output stack for discarded pages.
• When Jam Recovery is set to On or Auto, the printer reprints jammed pages. However, the Auto setting does not
guarantee that the page will print.
