Paper guidelines

Paper characteristics

The following paper characteristics affect print quality and reliability. Consider these factors before printing on them:

Weight

The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m2 (16–47‑lb) grain

paper. The 2100‑

Note: Two‑sided printing is supported for 60–176 g/m

(16–47‑lb) paper.

Curl

Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur after

paper

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 and 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.

Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing. Extend
the time
paper may also require a longer conditioning period.

several days if the storage or transportation environment is very different from the printer environment. Thick

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 60–176 g/m2 (16–47‑lb) paper, grain long paper is recommended.

General information

30

4063

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.

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 grain long for 60–90‑g/m2 (16–24‑lb) paper.

• Use only forms and letterhead printed using an offset lithographic or engraved printing process.

• Avoid paper with rough or heavily textured surfaces.

• 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.

• Print samples on preprinted forms and letterheads considered for use before buying large quantities. This

determines whether or not the ink in the preprinted form or letterhead will affect print quality.

• When in doubt, contact your paper supplier.

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
and discipline. Many factors are taken into consideration both separately and as a whole, including the following:

•

• 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)

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

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:

1 Minimize paper consumption.

2 Be 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.

3

Choose 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

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.

Data security notice

The symptoms described in this chapter might require replacement of one or more CRUs (Customer Replaceable Units)
designated as supplies or maintenance items, which are the responsibility of the customer. With the customer's
permission, you might need to install a developer (toner) cartridge.

Initial print quality check

Before troubleshooting specific print problems, complete the following initial print quality check:

1 Print a menu settings page, and then check the life status of all supplies. Any supplies that are low should be replaced.

Be sure to keep the original menu page to restore the customer's custom settings if needed.

2 On the menu page, make sure the following settings are at the default level:

• Print Resolution: Set to 600 dpi (print quality problems should be checked at different resolution settings).

• Toner Darkness: Set to 8 (default).

• Check the paper type, texture and weight settings against the paper that is loaded in the printer.

3 Inspect the transfer roller for damage. Replace, if damaged.

4 Inspect the print cartridge and imaging unit for damage. Replace, if damaged.

5

If paper other than 20 lb plain letter/A4 paper is being used, load 20 lb plain letter/A4 and print the Print Quality
pages to see if the problem remains. Use Tray 1 to test print quality problems.

6 Print the Print Quality Pages, and then look for variations in the print from what is expected.

7 Check to ensure the correct printer driver for the installed software is being used. An incorrect printer driver for

the installed software can cause problems. Incorrect characters could print, and the copy may not fit the page
correctly.

8 Measure all voltages from the connector to the printer ground.
