The multipurpose feeder can hold several sizes and types of print media, such as transparencies, labels, card stock, and
envelopes. It can be used for single-page or manual printing or as an additional tray.
The multipurpose feeder can hold approximately:
100 sheets of 75 g/m2 (20 lb) paper
10 envelopes
75 transparencies
The multipurpose feeder accepts paper or specialty media within the following dimensions:
Width—89 mm (3.5 in.) to 297 mm (11.7 in.)
Length—98.4 mm (3.8 in.) to 431.8 mm (17 in.)
Notes:
–Maximum width and length can be applied only to short-edge feeding.

							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 printer automatically senses the Paper Size setting according to the position of the paper guides in each tray except
the multipurpose feeder. The printer can sense A4, A5, JIS B5, Letter, Legal, Executive, and Universal paper sizes. The
multipurpose feeder and trays using other paper sizes can be linked manually using the Paper Size menu available from
the Paper Size/Type menu.
Note: To link the multipurpose feeder, Configure MP must be set to Cassette in the Paper menu in order for MP
Feeder Size to appear as a menu item.
The Paper Type setting must be set for all trays from the Paper Type menu 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.
Linking exit bins
The standard exit bin holds up to 500 sheets of 64–216 g/m2 (17–58 lb) paper, depending on the printer model. If you
need additional output capacity, you can purchase other optional exit bins.
Note: Not all exit bins support every paper size and type.
Linking exit bins lets you create a single output source so the printer can automatically switch output to the next available
exit bin.

							Paper and specialty media guidelines
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 60–128 g/m2 (16–34 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 inches), we recommend 90 g/m
2 (24 lb) or
heavier 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, then toner cannot fuse to it properly. If paper is
too smooth, then it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield
points; smoothness between 150 and 250 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 60–128 g/m
2 (16–34 lb bond) paper, grain long paper is recommended. For heavier paper, grain short is
recommended. Paper and specialty media guidelines 58

							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 64–216 g/m2 (17–58 lb) 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 guidelines 59

							Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40%. Most label
manufacturers recommend printing in a temperature range of 18 to 24°C (65 to 75°F) with relative humidity between
40 and 60%.
Store paper in cartons when possible, on a pallet or shelf, rather than on the floor.
Store individual packages on a flat surface.
Do not store anything on top of individual paper packages.
Supported paper sizes, types, and weights
The following tables provide information on standard and optional paper sources and the types of paper they support.
Note: For an unlisted paper size, configure a Universal Paper Size.
For information on card stock and labels, see the Card Stock & Label Guide on the Lexmark Web site at
http://support.lexmark.com.
