Selecting print media

Selecting the appropriate print media for th e MFP helps you avoid prin ti ng problems. The following secti ons contain guidelines for choosi ng the correct print media for the MFP.
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 MFP before bu ying 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, see the Card Stock & Label Gui de located on th e Lexmark Web s i te at www.lexmark.com.
The laser printing process heats paper to high temperatures of 230°C (446°F). For Magnetic Ink Character Recognition (MICR) applications and for non-MICR applicati ons, use only paper able to wi thstand these temperatures without discoloring, bleeding, or relea sing hazardous emission s. Check with the manufacturer or vendor to determine whether the paper you have chosen is accept able for laser printers.
Weight
The MFP can automatically feed paper weights from 60 to 176 g/m integrat ed and optional 500-sheet trays and paper wei ghts 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
2
90 g/m

Transparencies
The MFP can print directly on transparencies designed for use in laser printers. Print quality and durability depend on the transparency used. Alwa ys print samples on the transparencies you are co nsidering before buying large quantities.
The Paper Type setting should be set to Transparency to help prevent jams. In Macintosh, be sure to set the Paper Type to Transparency in the Print dialog on the Imagi ng choice in the Copies & Pag es pop-up menu.
Use transparencies designed spe cifically fo r laser printers. Che ck with the manufacturer or vendor to determine whether your transparencies are compatible with lase r pri nter s that heat transparencies to 230°C (446°F). Use only transpa rencies that are able to withstand these temperatures without melting, discoloring, offsetti ng, or releasing haz ardous emissions. For detailed information, see the Card Stoc k & 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. 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 ar e considering using with the MFP before buying large quantities.
When printing on envelopes:
To achieve the best possible print quality, use only high-quality envelopes 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 using. Set the paper type to Envelope, and select the correct envelope size from the operator panel, the MFP driver, or from MarkVision™ Professional.
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.
2
(20 lb bond) paper. You can use up to 105 g/m2
2
(28 lb bond) weig ht for the envelope feeder as
Use only new, undamaged envelopes.
For best performance and to mini m ize jams, do not use en velopes that:Have excessive curl or twist.Are stuck togethe r or damaged in any way.Contain windows, holes, perfo rations, cutouts or emb ossing.Use metal clasps, string ties, or metal folding bars.Have an inter locki ng desig n .Have postage stamps attached.Have any e xposed adhesiv e 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 230° C (446°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
The MFP can print on many label s designed for use with laser printers. These labels are supplied in letter si ze, A4 size, and l egal size sheets. Label adhesives, face sheet (printable stock) , and topcoats must be abl e to withstand temperatures of 230°C (446°F) and pressure of 25 pounds per square inch (psi).
Try a sample of any label s you are considering using wit h the MFP before purchasi ng a large quantity. For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide
ava il able 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 models require a special 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
follo w ing steps to maintain MFP feeding reliabil ity:
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
MFP operator panel, the MFP driv er, or from MarkVision Professional.
Feed vinyl labels f rom the standard 250- or 50 0-sheet tray s or the optional 250- or 500-sheet drawers. For
vinyl labels, set the Paper Type to Labels, the Labels Texture t o Smooth, and the Label W eight to Heavy, or set the Paper Type to vinyl l abels and the texture and weight to normal.
Do not load labels with paper or transparencies in the sa me source; mixing print media can cause feeding
problems and pri nt qual ity 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 the MFP and your cartridge with adhesive, and could v oid the MFP and cartridge warranties.
Use labels that can withstand temperatures of 230°C (446°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 adhes ive to the edge of the sheet. We recommend zone coating of the
adhesive at least 1 mm (0.04 in.) away from edges. Adhesi ve material contami nates the MFP and could void the war ranty.
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.) strip from the lea ding edge to prevent labels from peeling insi de the MFP.
Portrait orientation is preferred, especially when printing bar codes.
Do not use labels that have exposed 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 MFP 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 maintain MFP 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 MFP
driver, or from MarkVision Professional.
Be aware that preprinting, perf or atio n, and creasi ng can signi fica ntly af fec t the print qual ity 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 manufactured with chemicals that may contaminate the MFP. Preprinting
introduces semi-liquid and volatile component s int o the MFP.
We recommend the use of grain short card sto ck.

Storing print m edia

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 dir ectly on the floor.
If you store individual packages of paper out of the original carton, make sure they rest on a fl at 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 MFP.

Avoiding jams

Use appropriate print medi a (paper, tr ansparencies, l abels, and card stoc k) to help ensure trouble-free printing. Note: T ry a lim ited sample of any print media you are considering using with the MFP before purchasi ng 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 medi a sources . Mak e sure the sta ck heig ht does not e xc eed 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 feeding one
sheet at a time through the multipurpose feeder.
Do not use print media that you have cut or trimme d yourself.
Do not mix print media si zes, weights, or types in the same print media sou rce.
Make sure the recommended print side is loaded in the source according to your simplex or duplex needs.
1-16 Service Manual

A sheet of print media moves through the MFP to be printed. x represents the number of the sheet being printed. A sheet is c onsidered a
