Selecting print media

Selecting the appropriate print media for your printer helps you avoid printing problems. The following sections
contain guidelines for choosing the correct print media for your printer.

• Paper

• Transparencies

• Envelopes

• Labels

• Card stock

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 printer 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.

Weight

The printer 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/m
the multipurpose feeder. Paper lighter than 60 g/m (16 lb) might not be stiff
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 90 g/

2

(20 lb bond) grain long paper. When

Unacceptable paper

The following papers 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 ±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

2

(16 lb)

• Multiple-part forms or documents

General information 1-15

• For best performance and to minimize jams, do not use envelopes that:
– Have excessive curl or twist.
– Are stuck together or damaged in any way.
– Contain windows, holes, perforations, cutouts or embossing.
– Use metal clasps, string ties, or metal 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 nicked edges or bent corners.
– Have rough, cockle, or laid finishes.

• Use envelopes that can withstand temperatures of 225°C (437°F) without sealing, excessive curling,

wrinkling, or releasing hazardous emissions. If you have any doubts about the envelopes you are
considering using, check with the envelope supplier.

• Load only one size of envelope at a time in the envelope feeder.

• A combination of high humidity (over 60%) and the high printing temperatures may seal the envelopes.

Labels

Your printer can print on many labels designed for use with laser printers. These labels are supplied in

•

letter size, A4 size, and legal size sheets. Label adhesives, face sheet (printable stock), and topcoats must
be able to withstand temperatures of 225°C (437°F) and pressure of 25 pounds per square inch (psi).

• Try a sample of any labels you are considering using with the printer before purchasing a large quantity.

Note: Labels are one of the most difficult print media for laser printers. All printer models require a special fuser

cleaner for label applications to optimize feed reliability.

After printing approximately 10,000 pages of labels (or each time you replace the print cartridge), complete the
following steps to maintain printer feeding reliability:

1. Print five sheets of paper.

2. Wait approximately five seconds.

3. Print five more sheets of paper.

When printing on labels:

• Set the Paper Size/Type menu item to Labels in the Paper Menu. You can set the Paper Size/Type from the

printer operator panel, the printer driver, the Local Printer Setup Utility, or from MarkVision.

• Do not load labels with paper or transparencies in the same source; mixing print media can cause feeding

problems.

• Do not use label sheets with a 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 your printer and your cartridge with adhesive, and could void your printer and
cartridge warranties.

• Use labels that can withstand temperatures of 225°C (437°F) without sealing, excessive curling, wrinkling,

or releasing hazardous emissions.

• Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the

label.

• Do not use label sheets that have adhesive to the edge of the sheet. We recommend zone coating of the

adhesive at least 1 mm (0.04 in.) away from edges. Adhesive material contaminates your printer and could
void your warranty.

• If zone coating of the adhesive is not possible, a 3 mm (0.125 in.) strip should be removed on the leading

and driver edge, and a non-oozing adhesive should be used.

• Remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling inside the printer.

General information 1-17

• Portrait orientation is preferred, especially when printing bar codes.

• Do not use labels that have exposed adhesive.

Card stock

Card stock is single ply, and has a large array of properties, such as the moisture content, thickness, and texture,
that can significantly affect print quality. See “Supported print media” on page 1-8 for information on the
preferred weight and for the grain direction of print media.

Try a sample of any card stock you are considering using with the printer before purchasing a large quantity.

After printing approximately 10,000 pages of card stock (or each time you replace the print cartridge), complete
the following steps to maintain printer feeding reliability:

1. Print five sheets of paper.

2. Wait approximately five seconds.

3. Print five more sheets of paper.

When printing on card stock:

• Set the Paper Type menu item in the Paper Menu to Card Stock from the operator panel, from the printer

driver, in the Local Printer Setup Utility, or from MarkVision.

• Be aware that preprinting, perforation, and creasing can significantly affect the print quality and cause print

media handling or jamming problems.

• Avoid using card stock that may release hazardous emissions when heated.

• Do not use preprinted card stock manufactured with chemicals that may contaminate the printer.

Preprinting introduces semi-liquid and volatile components into the printer.

• We recommend the use of grain short card stock.

Storing print media

Use the following guidelines to avoid paper feeding problems and uneven print quality.

• Store paper in an environment where the temperature is approximately 21°C (70°F) and the relative

humidity is 40%.

• Store cartons of paper on a pallet or shelf rather than directly on the floor.

• If you store individual packages of paper out of the original carton, make sure they rest on a flat surface so

the edges do not buckle or curl.

• Do not place anything on top of paper packages.

• Store paper in its original wrapper until you load it into the printer.

1-18 Service Manual

Avoiding jams

Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing.
See “Supported print media” on page 1-8 for more information.

Note: Try a limited sample of any print media you are considering using with the printer before purchasing large
quantities.

By selecting the appropriate print media and loading it properly, you can avoid most jams.

The following hints can help you avoid jams:

• Use only recommended print media.

• Do not overload the print media sources. Make sure the stack height does not exceed the maximum height

indicated by the stack line on the labels in the sources.

• Do not load wrinkled, creased, damp, or curled print media.

• Flex, fan, and straighten print media before you load it. If jams do occur with print media, try feeding one

sheet at a time through the multipurpose feeder.

• Do not use print media that you have cut or trimmed yourself.

• Do not mix print media sizes, weights, or types in the same print media source.

• Make sure the recommended print side is loaded in the source according to your simplex or duplex needs.

• Keep print media stored in an acceptable environment. See “Storing print media” on page 1-18.

• Do not remove trays during a print job.

• Push all trays in firmly after loading them.

• Make sure the guides in the trays are properly positioned for the size of print media you have loaded. Make

sure the guides are not placed too tightly against the stack of print media.

Print area

The printable area is limited to within 4.2 mm (0.167 in.) of all edges of the media. Any information placed
outside this specified printable area does not print.
