							Linking and unlinking trays
Linking trays
Tray linking is useful for large print jobs or multiple copies. When one linked tray is empty, paper feeds from the next
linked tray. When the Paper Size and Paper Type settings are the same for any trays, the trays are automatically linked.
The Paper Size setting is automatically sensed according to the position of the paper guides in each tray except the
multipurpose feeder. The Paper Size setting for the multipurpose feeder must be set manually from the Paper Size
menu. The Paper Type setting must be set for all trays from the Paper Type menu. The Paper Type menu and the Paper
Size menu are both available from the Paper Size/Type menu.
Unlinking trays
Unlinked trays have settings that are not the same as the settings of any other tray.
To unlink a tray, change the following tray settings so that they do not match the settings of any other tray:
Paper Type (for example: Plain Paper, Letterhead, Custom Type )
Paper Type names describe the paper characteristics. If the name that best describes your paper is used by linked
trays, assign a different Paper Type name to the tray, such as Custom Type , or define your own custom name.
Paper Size (for example: letter, A4, statement)
Load a different paper size to change the Paper Size setting for a tray automatically. Paper Size settings for the
multipurpose feeder are not automatic; they must be set manually from the Paper Size menu.
Warning—Potential Damage: Do not assign a Paper Type name that does not accurately describe the type of paper
loaded in the tray. The temperature of the fuser varies according to the specified Paper Type. Paper may not be
properly processed if an inaccurate Paper Type is selected.
Assigning a Custom Type  name
Assign a Custom Type  name to a tray to link or unlink it. Associate the same Custom Type  name to each tray
that you want to link. Only trays with the same custom names assigned will link.

Paper guidelines
Paper characteristics
The following paper characteristics affect print quality and reliability. Consider these characteristics when evaluating
new paper stock.
Weight
The printer can automatically feed paper weights from 60 to 220 g/m2 (16 to 58 lb bond) grain long. Paper lighter than
60 g/m
2 (16 lb) might not be stiff enough to feed properly, causing jams. For best performance, use 75 g/m2 (20 lb
bond) grain long paper. For paper smaller than 182 x 257 mm (7.2 x 10.1 in.), we recommend 90 g/m
2 (24 lb) or heavier
paper.
Note: Duplex is supported only for 63 g/m
2–170 g/m2 (17 lb–45 lb bond) paper.
Curl
Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can occur after
the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid,
cold, or dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding
problems.
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;
however, smoothness between 150 and 200 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.
Condition paper before printing by storing it in its original wrapper in the same environment as the printer for 24 to
48 hours before printing. Extend the time several days if the storage or transportation environment is very different
from the printer environment. Thick paper may also require a longer conditioning period.
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 to 135 g/m
2 (16 to 36 lb bond) paper, grain long paper is recommended. For papers heavier than 135 g/m2, grain
short is recommended. Paper and specialty media guide36

							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.
Unacceptable paper
The following paper types 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 ±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)
Paper weighing less than 60 g/m2 (16 lb)
Multiple‑part forms or documents
Selecting paper
Using appropriate paper prevents jams and helps ensure trouble‑free printing.
To help avoid jams and poor print quality:
Always use new, undamaged paper.
Before loading paper, know the recommended print 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 source; mixing results in jams.
Do not use coated papers unless they are specifically designed for electrophotographic printing.
Selecting preprinted forms and letterhead
Use these guidelines when selecting preprinted forms and letterhead:
Use grain long for 60 to 90 g/m2 weight paper.
Use only forms and letterhead printed using an offset lithographic or engraved printing process.
Avoid papers with rough or heavily textured surfaces.
Use papers printed with heat‑resistant inks designed for use in xerographic copiers. The ink must be able to withstand
temperatures up to 230°C (446°F) without melting or releasing hazardous emissions. 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.
When in doubt, contact the paper supplier. Paper and specialty media guide37

							Preprinted papers such as letterhead must be able to withstand temperatures up to 230°C (446°F) without melting or
releasing hazardous emissions.
Using recycled paper
As an environmentally conscious company, Lexmark supports the use of recycled office paper produced specifically for
use in laser (electrophotographic) printers. In 1998, Lexmark presented to the US government a study demonstrating
that recycled paper produced by major mills in the US fed as well as non-recycled paper. However, no blanket statement
can be made that all recycled paper will feed well.
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of test paper
from around the world, using chamber tests for different temperature and humidity conditions. Lexmark has found no
reason to discourage the use of todays recycled office papers, but generally the following property guidelines apply
to recycled paper.
Low moisture content (4–5%)
Suitable smoothness (100–200 Sheffield units)
Suitable sheet-to-sheet coefficient of friction (0.4–0.6)
Sufficient bending resistance in the direction of feed
Recycled paper, paper of lower weight (

Using transparencies
Print samples on the transparencies being considered for use before buying large quantities.
When printing on transparencies:
From MarkVision Professional, Print Properties, or the control panel, set the Paper Type to Transparency.
Feed transparencies from the standard tray or the multipurpose feeder.
Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure
transparencies are able to withstand temperatures up to 230°C (446°F) without melting, discoloring, offsetting, or
releasing hazardous emissions.
Use transparencies that are 0.12–0.14 mm (4.8–5.4 mil) in thickness or 161–179 g/m2 in weight. Print quality and
durability depend on the transparencies used.
To prevent print quality problems, avoid getting fingerprints on the transparencies.
Before loading transparencies, fan the stack to prevent sheets from sticking together.
We recommend Lexmark part number 12A8240 for letter‑size transparencies.
Using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
When printing on envelopes:
From the control panel, set the Paper Source based on the source in use. From MarkVision Professional, Print
Properties, or the control panel, set the Paper Type to Envelope, and select the envelope size.
Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the
envelopes can withstand temperatures up to 230°C (446°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
For the best performance, use envelopes made from 90 g/m2 (24 lb bond) paper. Use up to 105 g/m2 (28 lb bond)
weight for envelopes as long as the cotton content is 25% or less. All‑cotton envelopes must not exceed 90 g/m
2
(24 lb bond) weight.
Use only new envelopes.
To optimize performance and minimize jams, do not use envelopes that:
–Have excessive curl or twist
–Are stuck together or damaged in any way Paper and specialty media guide40
