| Print Media Guidelines
• For the best print quality in black and white, use 90 g/m
2
(24 lb) xerographic, grain
long paper.
• Print media designed for general business use also provides acceptable print quality.
• Laser printing process heats print media to high temperatures. Only use paper able
to withstand high temperatures without discoloring, bleeding, or releasing
hazardous emissions. Check with the manufacturer or vendor to determine whether
the paper you have chosen is acceptable for laser printers.
Recommended Pre-Printed Media and Letterheads
• Use grain long paper for best results.
• Use only forms and letterheads printed using an offset lithographic or engraved
printing process.
• Use print media that absorb ink, but does not bleed.
• Avoid print media with rough or heavily textured surfaces.
• Use print media printed with heat-resistant inks designed for use in xerographic
copying machines. The ink must withstand temperatures of 225°C (437°F) without
melting or releasing hazardous emissions.
• Use print media printed with inks that are not affected by the resin in the toner or the
silicone in the fusing unit. Inks that are oxidation-set or oil-based should meet these
requirements; latex inks might not. If you are in doubt, contact your paper supplier.
Recommended Pre-Punched Print Media
• Use only pre-punched paper made at the paper manufacturer.
• Do not drill print media which are already packaged in a ream. Using them may
result in paper jams.
• Pre-punched print media can include more paper dust than standard print media.
The printer may require more frequent cleaning, and feed reliability may not be as
good as standard print media.
• Weight guidelines for pre-punched print media are the same as non-punched print
media.
Recommended Envelopes
Depending on the envelopes, it is possible to expect variable levels of wrinkling.
• Use only high-quality envelopes that are designed for use in laser printers.
• Use envelopes made from 75 g/m
2
(20 lb bond) paper. You can use up to 105 g/m
2
(28 lb bond) weight for the envelope feeder as long as the cotton content is 25
percent or less. Envelopes with 100 percent cotton content must not exceed 90
g/m
2
(24 lb bond) weight.
• Use envelopes that can withstand temperatures of 205°C (401°F) without sealing,
excessive curling, wrinkling, or releasing hazardous emissions. If you are in doubt,
contact your envelope supplier.
• Check for high humidity. High humidity (higher than 60 percent) and high printing
temperature may seal the envelopes.
• Do not use envelopes that:
– Have excessive curl or twist
