Envelopes
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within
a box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When
selecting envelopes, consider the following factors:
• Weight: The weight of the envelope paper should not exceed
90g/m
2
(24lb) or jamming may occur.
• Construction: Prior to printing, envelopes should lie flat with
less than 6mm (0.25in.) curl, and should not contain air.
• Condition: Envelopes should not be wrinkled, nicked, or
otherwise damaged.
• Temperature: You should use envelopes that are compatible
with the heat and pressure of the printer.
• Size: You should only use envelopes within the following size
ranges.
NOTES
:
• Use only the Multi-purpose Tray to print envelopes.
• You may experience some paper jams when using any media
with a length less than 140mm
(
5.5in.). This may be caused
by paper that has been affected by environmental
conditions. For optimum performance, make sure you are
storing and handling the paper correctly. Please refer to
“Printer and Paper Storage Environment” on page 10.3.
Envelopes with Double Side Seams
Double side-seam construction has vertical seams at both ends
of the envelope rather than diagonal seams. This style may be
more likely to wrinkle. Be sure the seam extends all the way to
the corner of the envelope as illustrated below.
Minimum Maximum
Multi-purpose Tray 3.5 x 5.5in.

Envelopes with Adhesive Strips or Flaps
Envelopes with a peel-off adhesive strip or with more than one
flap that folds over to seal must use adhesives compatible with
the heat and pressure in the printer. The extra flaps and strips
might cause wrinkling, creasing, or even jams and may even
damage the fuser.
Envelope Margins
The following gives typical address margins for a commercial
#10 or DL envelope.
NOTES
:
• For best print quality, position margins no closer than 15mm
(0.6in.) from the edges of the envelope.
• Avoid printing over the area where the envelope’s seams
meet.
Envelope Storage
Proper storage of envelopes helps contribute to print quality.
Envelopes should be stored flat. If air is trapped in an envelope,
creating an air bubble, then the envelope may wrinkle during
printing. See “Printing on Envelopes” on page 4.4.
Labels
CAUTION
:
• To avoid damaging the printer, use only labels recommended
for laser printers.
• To prevent serious jams, always use the Multi-purpose Tray
to print labels and always use the rear output tray.
• Never print on the same sheet of labels more than once and
never print on a partial sheet of labels.
When selecting labels, consider the quality of each component:
• Adhesives: The adhesive material should be stable at 180°C
(356°F), the printer’s fusing temperature.
• Arrangement: Only use labels with no exposed backing
between them. Labels can peel off sheets with spaces
between the labels, causing serious jams.
• Curl: Prior to printing, labels must lie flat with no more than
5in. (13mm) of curl in any direction.
• Condition: Do not use labels with wrinkles, bubbles, or other
indications of separation.
See “Printing on Labels” on page 4.5.
