Selecting paper
Paper guidelines
Use the appropriate paper to prevent jams and help ensure trouble‑free printing.
• Always use new, undamaged paper.
• Before loading paper, know the recommended printable 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 tray; mixing results in jams.
• Do not use coated papers unless they are specifically designed for electrophotographic printing.
Paper characteristics
The following paper characteristics aect print quality and reliability. Consider these factors before printing on
them.
Weight
The trays can feed paper weights from 60 to 176 g/m2 (16 to 47 lb) grain long paper. Paper lighter than
60 g/m
2
(16 lb) may not be sti enough to feed properly, and may cause jams.
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 can contribute to paper curling before printing and can cause
feeding problems.
Smoothness
Paper smoothness directly aects 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. We recommend the use of paper with 50
Sheeld
points.
Moisture content
The amount of moisture in paper
Leave paper in its original wrapper until you use it. Exposure of paper to moisture changes can degrade its
performance.
Store paper 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 dierent from the printer
environment. Thick paper may also require a longer conditioning period.
aects
both print quality and the printer ability to feed the paper correctly.
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.
2
For 60–176 g/m
(16–47‑lb) paper, grain long paper is recommended.
Learn about the printer14
Fiber content
Most high‑quality xerographic paper is made from 100 percent 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 aect 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 aected 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.
• Rough‑edged, rough or heavily textured surface papers, or curled papers
• Recycled papers that fail EN12281:2002 (European)
• Paper weighing less than 60 g/m
• Multiple‑part forms or documents
2
(16 lb)
Storing paper
Use these paper storage guidelines to help avoid jams and uneven print quality:
• Store paper 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 dierent from the printer
environment. Thick paper may also require a longer conditioning period.
• For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent.
• Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative
humidity between 40 and 60 percent.
• Store paper in cartons, 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.
• Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and
wrapper help keep the paper clean, dry, and flat.
Selecting preprinted forms and letterhead
• Use grain long paper.
• Use only forms and letterhead printed using an oset lithographic or engraved printing process.
• Avoid paper with rough or heavily textured surfaces.
• Use inks that are not aected by the resin in toner. Inks that are oxidation‑set or oil‑based generally meet
these requirements; latex inks might not.
Learn about the printer15
• Print samples on preprinted forms and letterheads considered for use before buying large quantities. This
action determines whether the ink in the preprinted form or letterhead
aects
print quality.
• When in doubt, contact your paper supplier.
• When printing on letterhead, load the paper in the proper orientation for your printer. For more information,
see the Paper and Specialty Media Guide.
