Selecting print media

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

• Paper

• Transparencies

• Envelopes

• Labels

• Card stock

Paper

For the best print qual ity, use 75 g/m2 (20 lb) xerographic, grain long paper. Try a sample of any paper you are considering using with the MFP before buying large quantities.

When loading paper, note the recommended print sid e 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 tem peratures of 230°C (446°F). For Magnetic Ink Character Recognition (MICR) applications and for non-MICR appl ications, use only paper able to withstand these temperatures without discoloring, bleeding, or releasing hazardous emissions. Check with the manufacturer or vendor to determi ne whether the paper you have chosen is acceptable for laser printers.

Weight

The MFP can automatical ly feed paper weights from 60 to 176 g/m integrate d and opti onal 500-sheet trays and paper weights from 60 to 135 g/m the multipurpose feeder and optional 250-sheet trays. Paper lighter than 60g/m enough to feed properly, causing jams. For b est performance, use 75 g/m using paper narr ower t han 182 x 257 m m (7.2 x 10.1 in.), make sure the weight is greater than or equal to

90 g/m

Unacceptable paper

The following papers are not recommended for use with the MFP:

(24 lb bond).

(16 to 47 lb bond) grain long in the

• Some chemically treated papers used to make copies wi thout carbon paper, also known as car bonless

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 pap ers that can be affected by the temperature in the MFP fuser

• Preprinted p apers that require a registration (the precise print l ocation on the page) greater than ±0.09 in.,

such as optical character recognition (OCR) form s

• In some cases, you can adjust registration with your software appli cation to successf ully print on these

forms.

• Coated papers (era sable bond), synthetic papers, thermal papers

• Rough-edged, rough or heavily textured surface papers or curled papers

Transparencies

The MFP can print directl y on transparencies designed for use in laser printers. Print quality and durabili ty depend on the transparency used. Always print samples on the transparencies you are considering before buying large quantities.

The Paper Type setti ng should be set to Transparency to hel p prevent jams. In Macintosh, be sure t o set the Paper Type to Transpar ency in the Print dialog on the Imagin g choi ce in the Copies & Pages pop-up menu.

Use transparencies designed s pecifically for laser printers. Check with the manufacturer or vendor to determine whether your transparencies are compatible with laser printers that heat transparencies to 230°C (446°F). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. For detailed information, see the Card Stock & Label Guide, which is available on the Lexmark Web site at www.lexmark.com.

Transparencies can be fed automaticall y from the multipurpose feeder and all standard and optional trays, except the 2000-sheet drawer. Before loading transparencies, fan the stack to prevent sheets from sticking together.

Be careful when you handle transparencies. Fingerprints on the surface of the transparency cause poor print quality.

Envelopes

You can load up to 10 envelopes in the multipurpose feeder and 85 envelopes in the envelope feeder. Try a sample of any envelopes you are considering using with the MFP before buying large quantities.

When printing on envelopes:

• To achieve t he b est poss ib le pr int qu alit y, use only h ig h-quali ty e nvelopes t hat are des igned f or use i n laser

printers.

• Set the Paper Size/Type in the Paper menu to MP Feeder, Manual Env, or Env Feeder depending on the

source you are using . Set the paper type to Envelope, and select the correct envelope si ze from the operator panel , t he MFP driver, or from MarkVision™ Profession al.

• For best perf ormance, use envelopes made from 75 g/m

(28 lb bond) weight for the mul tipurpose feede r or 105 g/m long as the cotton content is 25% or less. Envelopes with 100% cotton content must not exceed 90 g/m (24 lb bond) weight.

(20 lb bond) paper. You can use up to 105 g/m2

(28 lb bond) weight for the en velope feeder as

• Use only new, undamaged envelopes.

• For best performa nce 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 st am ps att ached. – Have any exposed adhesive when the flap is in the sealed or clos ed position. – Have nicked edges or bent corners. – Have rough, cockle, or laid finishes.

• Use envelopes that can withstand temperatures of 230°C (446°F) without sealing, excessive curling,

wrinkling, or r eleasing hazardous emiss ions. If you have any doubts about the envelopes you are considerin g using, check with the envelope supplier.

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

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

Labels

The MFP can print on many label s designed for use with laser print ers. These labels are supplied in letter size, A4 size, and legal size sheets. Label adhesives, face sheet (printab le st ock), and topcoats must be able to withstand tempe ratures of 230°C (446°F) and pres sure of 25 pounds per square inch (psi).

Try a sample of any labels you are considering using wit h the MFP before purchasing a large quant ity. For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide

available on the Lexmark Web site at www.lexmark.com/publications. Note: Labels are one of the most difficul t print media for laser MFPs. All MFP model s require a special fuser

cleaner for label applications to optimize feed reliability. After printi ng approximately 10,000 pages of l abels (or each time you replace the print cartridge), comp lete the

following steps to maintain MFP feeding reliability:

1. Print five sheets of paper.

2. Wait approximately five seconds.

3. Prin t five more sheets of paper.

When printing on labels:

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

MFP operator panel, the MFP driver, or from MarkVision Prof essional.

• Feed vinyl l abels from the st andard 250- or 500-sheet trays or the optional 250- or 500-sheet drawe rs. For

vinyl labels, set the Paper Type to Labels, the Labels Texture to Smooth, and the Label Weight to Heavy, or set the Paper Type to vinyl labels and the texture and weight to normal.

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

problems and print quality problems.

• Do not use label sheets with a slick backing material.

• Use full label sheet s. Partial sheets may cause lab els to peel off during printing, resulting in a jam. Partia l

sheets also cont am inate the MFP and your cartridge with adhesive, and could void the MFP and cartridge warranties.

• Use labels t hat can withstand temperatures of 230°C (4 46° 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 shee t. We recommend zone coating of the

adhesive at leas t 1 mm (0.04 i n.) away from edges. Adhesive material contaminates the MFP and could void the warranty.

• If zone coating of the adhesive is not possible , a 1.6 mm (0. 1 in. ) strip should be removed on the leading

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

• Remove a 1.6 mm (0.1 in.) stri p from the leading edge to prevent labels from peeling inside th e MFP.

• Portrait ori entation 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 properti es, such as the moisture cont ent, thickness , and texture, that can signifi cantly affect print quality. See “Supported print media” on page 1-9 for information on the preferred weight and for the grain direction of print media.

Try a sample of any card st ock you are considering using wit h the MFP before purchasing a large quantity. After printi ng approximately 10,000 pages of card stock (or each time you r eplace the print cartridge), complete

the following st eps to maintain MFP feeding reliability:

1. Print five sheets of paper.

2. Wait approximately five seconds.

3. Prin t five more sheets of paper.

When printing on car d stock:

• Set the Paper Type menu item in the Paper menu to Card Stock from the operator panel, from th e MFP

driver, or from Mark Vision Professional.

• Be aware that preprint ing, per forat ion, and creasi ng can signi fica ntly affec t the pri nt qualit y and caus e print

media handling or jamm ing problems.

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

• Do not use preprinted card stock manufactured with chemi cals that may contaminate the M FP. Preprinting

introduces semi-liquid and volatil e com ponents into the MFP.

• We recommend the use of grain short card stock.

Storing print m edia

Use the following gui delines to avoid paper feedi ng problems and uneven print quali ty.

• 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 individu al packages of paper out of the original carton, make sure they rest on a flat surf ace 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 i t in to t he MFP.

Avoidi ng j ams

Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing. Note: Try a limited sample of any print media you are considering using with the MFP befor e purchasing large

quantities. By selecting the appropriate print media and loadi ng it properly, you can avoid mos t ja ms . The following hint s can help you avoid jams:

• Use only recommended print media.

• Do not overload th e print med ia sourc es. Mak e sure the st ack heig ht does not exceed the maximu m height

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

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

• Flex, fan, and strai ghten print media before you l oad it. If jams do occur with print med ia, 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 recom m ended print side is loaded in the source according to your simplex or duplex needs .

1-16 Service Manual

7002-xxx

• Keep print media stored in an acceptable environment. See “Storing print media” on page 1-16.

• Do not remove trays dur ing a print job.

• Push all trays in firmly after loading them.

• Make sure the gui des i n the trays are p roperl y posit ioned f or the s ize of p rint media you hav e lo aded. Make

sure the guides are not pl aced too tightly against the st ack of print media.

• If a jam occurs, clear the entire media path.

A sheet of print media moves through the MFP to be printed. x represents the number of the sheet being printed. Even though a duplex

sheet has two sides, called pages, it only counts as one sheet. So, pages are not counted, only sheets passing through the MFP.

The total number of sheets in a set is not known, but the number of sets is known. For example, a user may have requested that three copies print, so there are three sets of sheets, but the number of sheets is unknown.

A sheet of print media moves through the MFP to be printed. x represents the number of the s heet being printed. A sheet is considered a
