							4Push the paper pick tab, and then load the paper or specialty media. Slide the stack gently into the
multipurpose feeder until it comes to a stop, and then release the paper pick tab.
Warning—Potential Damage: Pulling the paper out, without pushing the paper pick tab 
first, may cause
jams or the paper pick tab to break.
Load paper and transparencies with the recommended print side facedown and the long edge entering
the printer first.
For duplex letterhead printing, place the letterhead faceup and the header entering the printer last.
Load envelopes with the flap side up and to the right.
Warning—Potential Damage: Never use envelopes with stamps, clasps, snaps, windows, coated
linings, or self‑stick adhesives. These envelopes may severely damage the printer.
Notes:
Do not exceed the maximum stack height by forcing paper or transparencies under the stack height
limiter.
Load only one size and type of paper at a time. Loading paper and specialty media 71 
						

							5Adjust the width guide to lightly touch the edge of the stack. Make sure the paper or specialty media fits
loosely in the multipurpose feeder, lies flat, and is not bent or wrinkled.
6From the printer control panel, set the Paper Size and Paper Type for the multipurpose feeder (MP Feeder
Size and MP Feeder Type) based on the paper or specialty media loaded.
Linking and unlinking trays
When one linked tray becomes empty, paper feeds from the next linked tray. We recommend giving all custom
paper, such as letterhead and different colored plain papers, a different custom type name so that the trays
they are in do not automatically link.

Paper guidelines
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when
evaluating new paper stock.
Weight
The printer trays can automatically feed paper weights from 60 to 300 g/m2 (16–80 lb bond) grain long. Paper
lighter than 60 g/m
2 (16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use
75 g/m
2 (20 lb bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend
90 g/m
2 (24 lb) or heavier paper.
Notes:
The duplex unit supports only 60–169 g/m2 (16–32 lb bond) paper weights.
The multipurpose feeder supports 60–300 g/m2 (16–80 lb bond) paper weights.
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, then toner cannot fuse to it properly. If
paper is too smooth, then it can cause paper feeding or print quality issues. Always use paper between 100
and 300 Sheffield points; however, smoothness between 150 and 200 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. Paper and specialty media guide74 
						

							Store paper in its original wrapper in the same environment as the printer for 24 to 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.
For 60–135 g/m
2 (16–36 lb bond) paper, grain long paper is recommended. For papers heavier than 135 g/m2,
grain short 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 ±2.3 mm
(±0.9 in.), 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/m2 (16 lb)
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. Paper and specialty media guide75 
						

							Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
Use grain long for 60 to 90 g/m2 (16 to 24 lb) weight paper.
Use only forms and letterhead printed using an offset lithographic or engraved printing process.
Avoid papers with rough or heavily textured surfaces.
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.
Using recycled paper and other 
office papers
As an environmentally conscientious company, Lexmark supports the use of recycled paper produced
specifically for use in laser (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. Many factors are taken into consideration both separately and as a whole, including
the following:
Amount of post-consumer waste (Lexmark tests up to 100% post-consumer waste content.)
Temperature and humidity conditions (Testing chambers simulate climates from all over the world.)
Moisture content (Business papers should have low moisture: 4–5%.)
Bending resistance and proper stiffness means optimum feeding through the printer.
Thickness (impacts how much can be loaded into a tray)
Surface roughness (measured in Sheffield units, impacts print clarity and how well toner fuses to the paper)
Surface friction (determines how easily sheets can be separated)
Grain and formation (impacts curling, which also 
influences the mechanics of how the paper behaves as it
moves through the printer)
Brightness and texture (look and feel)
Recycled papers are better than ever; however, the amount of recycled content in a paper 
affects the degree
of control over foreign matter. And while recycled papers are one good path to printing in an environmentally
responsible manner, they are not perfect. The energy required to de-ink and deal with additives such as
colorants and “glue” often generates more carbon emissions than does normal paper production. However,
using recycled papers enables better resource management overall.
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). This
is due to the energy-intensive manufacturing processes required to make paper.
Thus, Lexmark seeks to educate customers and partners on minimizing the impact of paper. Using recycled
paper is one way. Eliminating excessive and unnecessary paper consumption is another. Lexmark is well-
equipped to help customers minimize printing and copying waste. In addition, the company encourages
purchasing paper from suppliers who demonstrate their commitment to sustainable forestry practices. Paper and specialty media guide76 
						

							Lexmark does not endorse specific suppliers, although a converter’s product list for special applications is
maintained. However, the following paper choice guidelines will help alleviate the environmental impact of
printing:
1Minimize paper consumption.
2Be selective about the origin of wood fiber. Buy from suppliers who carry certifications such as the Forestry
Stewardship Council (FSC) or the Program for the Endorsement of Forest 
Certification (PEFC). These
certifications guarantee that the paper manufacturer uses wood pulp from forestry operators that employ
environmentally and socially responsible forest management and restoration practices.
3Choose the most appropriate paper for printing needs: normal 75 or 80 g/m2 
certified paper, lower weight
paper, or recycled paper.
Unacceptable paper examples
Test results indicate that the following paper types are at risk for use with laser printers:
Chemically treated papers used to make copies without carbon paper, also known as carbonless papers
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 location on the page) greater than ± 2.3 mm (±
0.9 in.), 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 testing)
Paper weighing less than 60 g/m2 (16 lb)
Multiple part forms or documents

www.lexmark.com. General sustainability-related information can
be found at the Environmental Sustainability link.
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. Paper and specialty media guide77
