Print Media Guidelines
177
Envelopes
Depending on the envelopes, it is possible to expect variable levels of wrinkling. It is recommended that you try a
sample first before buying large quantities of any print media. See
"
Loading Envelopes in the MPF
"
for instructions
on loading envelopes.
When printing on envelopes:
• Use only high-quality envelopes that are designed for use in laser printers.
• Set the print media source to the MPF. Set the paper type to
Envelope
, and select the correct size of envelope from
the printer driver.
• 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 % or less. Envelopes with 100 % cotton content must not exceed
90 g/m
2
(24 lb bond) weight.
• Use only freshly unpackaged, undamaged envelopes.
• Use envelopes that can withstand temperatures of 205 °C (401 °F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions. If you have any doubts about the envelopes you are considering, check with the
envelope supplier.
• Adjust the guide to fit the width of the envelopes.
• To load an envelope into the MPF, insert the envelope with the flaps closed or open and the short-edge of the
envelope facing into the printer. The print side must be facing up.
• See "
Loading Envelopes in the MPF
" for instructions on loading envelopes.
• Use one envelope size during a print job.
• Ensure that the humidity is low because high humidity (more than 60 %) and the high printing temperatures may
seal the envelopes.
• For best performance, do not use envelopes that:
– Have excessive curl or twist
– Are stuck together or damaged in any way
– Contain windows, holes, perforations, cutouts, or embossing
– Use metal clasps, string ties, or metal folding bars
– Have an interlocking design
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed or closed position
– Have nicked edges or bent corners
– Have rough, cockle, or laid finishes
Labels
Your printer can print on many labels designed only for use with laser printers.
When selecting labels:
• Label adhesives, face sheet (printable stock), and topcoats must be able to withstand temperatures of 205 °C (401
°F) and pressure of 25 pounds per square inch (psi).
• Use labels that can be without sealing, excessive curling, wrinkling, or releasing hazardous emissions.
• Do not use label sheets with a slick backing material.
CAUTION:
Before buying large quantities of any print media, it is recommended that you try a sample first.
