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 befo re buying large quantities.

When loading paper, note the recommended print side on the paper package, and load paper acco rdingly.

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, refer to the Card Stock & Label Guid e located on the Lexmark Web site at www.lexmark.com.

The laser printing process heats paper to high temperatures of 225°C (437°F) for Magnetic Ink Character Recognition (MICR) app li cations, and 205°C (401°F) for non-MICR applications. Use only paper able to withstand these temperatures without discoloring, blee ding, or releasing hazardous emissions. Check with the manuf acturer or vendor to determine whether the paper you have chosen is accepta ble for laser printers.

Weight

The printer can automatically feed paper weights from 60 to 176 g/m2 (16 to 47 lb bond) grain l ong in the integrated and optional 500–sheet trays and paper weights from 60 to 135 g/m the multipurpose feeder and optional 250–sheet trays. Paper lighter than 60 g/m enough to feed properly, causing jams. For best performance, use 75g/m using paper narr ower than 182 x 257 mm (7.2 x 10.1 in.), make sure the weight is greater than or equal to 90 g/

(24 lb bond).

Unacce p tab l e p ap er

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 paper s,

carbonless copy paper (CCP), or no carbon required (NCR) paper

• Preprinted papers with chemicals that may contaminate the printer

• Preprinted papers that can be affe cted by the temperatur e in the printer fuser

• Preprinted papers that require a registration (the precise print l ocation 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 appli cation to successf ull y print on these

forms.

• Coated papers (erasable bond), synthetic papers, thermal papers

• Rough-edged, rough or heavil y 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

Transparencies

You can feed transparencies fr om the standard tr ay (250-sheet t ray for the T111 or 500-sheet tra y for the T112), optional 250- or 500-sheet tray s, or the multipurpose f eeder. Try a sample of any transparencies you are considering using with the printer befo re buying large quantities.

When printing on transparencies:

• Be sure to set the Paper Type to Transparency from the printer driver or the Local Printer Setup Utility to

avo id damaging your printer.

• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand

temperatures of 225°C (437°F) without melt ing, discoloring, offsetting or releasing hazardous emissions.

• To prevent print quality problems , avoid gett ing fingerprints on the transpar encies.

• Before loading transparencies, fan the stack to prevent sheets from sticking together.

Selecting tr anspare n ci es

The printer can print directly on transparencies designed for use in laser printers. Print qua li ty and durability depend on the transparency used. Alwa ys print samples on the transparencies you are considering before buying large quantities.

The Paper Type setting should be set to Transparency to help prevent jams. Check with the manufacturer or vendor to determine whether your tran sparencies are compatible with laser printer s that heat transparenci es to 225°C (437°F). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasi ng hazardous emissions. For detailed information, refer to the Card Stock & Label Guide, which is available on the Lexmark Web site at www.lexmark.com.

Transparencies can be fed automatically fr om the multipurpose feeder and all standard and optional tr ays, except the 2000-sheet drawer.

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 ar e considering using with the printer before buying l arge quantities.

When printing on envelopes:

• To achieve the best possible print quality, use only high-quality envel opes that are designed for use in 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 usi ng, set the paper type to Envelope, and select the correct envelope size from the operator panel, the printer driver, in the Local Printer Setup Utility, or from MarkVision™.

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

(28 lb bond) weight for the multipurpose feeder 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) weig ht for the envelope feeder as

• Use only new, undamaged envelopes.

General information 1-17

Page 38

4061-xx0

• For best performance and to mini m ize jams, do not use en velopes that: – Have excessive curl or twist. – Are stuck together or damaged in an y way. – Contain windows, holes, perforati ons, cutouts or embossi ng. – Use metal clasps, string ties, or metal folding bars. – H ave a n inter locking design . – Have postage stamps attached. – Have any exposed adhesive when the fl ap is i n the sealed or closed positi on. – Have nicked edges or bent corners. – Have rough, cockle, or laid finishes.

• Use envelopes that can with stand temperatures of 225° C (437°F) without sealing, excessive curl ing,

wrinkling, or releasing hazardous emissions. If you have any doubts abou t the envelopes you are considering using, check with the en velope 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 sheet s. 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 consi deri ng using with the printer before purchasing a larg e quantity.

• For detailed information on label printing, characteristics, and design, refer to the Card Stock & Label

Guide available on the Lexmark Web site at www.lexmark.com/publications.

Note: Labels are one of the most difficult print media for l aser printers . All printer models requ ire a speci al fuser

cleaner f or label application s to opt imize feed rel iability. After printing approximately 10,000 pages of labels (or each tim e 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 P ape r Menu . You can set the Pape r Size/ Type from the

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

• Feed vinyl labels from the standard 250- or 500-sheet tr ays, or the optional 250- or 500-sheet drawers. For

vinyl l abels, you must set the Paper Type to Labels, the Labels Texture to Smooth, and t he Label Wei ght to Heavy.

• Do not load labels with paper or transparencies in the sa me 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 cont am inate your printer and y our cartridge wi th adhesive, and coul d void your printer and cartridge warranti es.

• Use labels that can withstand temperatures o f 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 zon e coating of the

adhesive at l east 1 mm (0.04 in.) aw a y from edges . Adhesiv e material cont aminate s yo ur 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 in side the printer.

1-18 Service Manual

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

• Do not use labels that have e xposed adhesive.

Card stock

Card stock i s sin gle ply, and has a large ar r ay o f pr operties, s uch a s the mois ture co nte nt, t hick ness , and t ex tur e, that can signifi cantly affec t pri nt qual ity. See “Supported print media” on page 1-9 for information on the preferred weight and for th e grain direction of print media.

Try a sample of any card st ock you are consideri ng using with the printer before purchasing a large quantity. After printing ap proximately 10,000 pages of card stock (or each time you replace the print cartridge), complete

the following steps to maintai n pri nter 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 Uti lity, or from MarkVision.

• Be aware that preprinting, perf or atio n, and creasi ng can signi fica ntly af fec t the print quality and cause print

media handling or jamm ing problems.

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

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

Preprinting int roduces 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 ca rton, mak e sure the y 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.

Av o iding jams

Use appropriate print medi a (paper, tr ansparencies, l abels, and card stoc k) to help ensure trouble-free printing. See “Supported print media” on page 1-9 for more information.

Note: Try a limited sample of any pri nt media you are considering using with the printer be fore purchasing large quantities.

By selecting the appropriate print media and loading i t properly, you can av oid 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 stac k heig ht does not e xceed the maximum hei ght

indicated b y the stack line on the label s 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 feedi ng 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 med ia source.

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

• Keep print media stored in an acce ptable enviro nm ent. See “Storing print media” on page 1-19.

• Do not remove trays during a print job.

• Push all trays in firmly after loading them.

• Make sure the guides in the tra ys are properly pos iti oned f or the si ze of print media yo u ha ve loa ded. Make

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