MEDIA TYPE GUIDELINES
Envelopes • 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 90 g/m 2 or jamming may occur.
- Construction: Prior to printing, envelopes should
lie flat with less than 6 mm 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
machine during operation.
• Use only well-constructed envelopes with sharp and
well creased folds.
• Do not use stamped envelopes.
• Do not use envelopes with clasps, snaps, windows,
coated lining, self-adhesive seals, or other synthetic
materials.
• Do not use damaged or poorly made envelopes.
• Be sure the seam at both ends of the envelope
extends all the way to the corner of the envelope.

• Envelopes with a peel-off adhesive strip or with
more than one flap that folds over to seal must use
adhesives compatible with the machine’s fusing
temperature for 0.1 second. Check your machine’s
specification to view the fusing temperature, see
page 40. The extra flaps and strips might cause
wrinkling, creasing, or jams, and may even damage
the fuser.
• For the best print quality, position margins no closer
than 15 mm from the edges of the envelope.
• Avoid printing over the area where the envelope’s
seams meet.
Labels • To avoid damaging the machine, use only labels
designed for use in laser machines.
- When selecting labels, consider the following
factors:
- Adhesives: The adhesive material should be
stable at your machine’s fusing temperature.
Check your machine’s specification to view the
fusing temperature, see page 40.
- Arrangement: Only use labels with no exposed
backing between them. Labels can peel off sheets
that have spaces between the labels, causing
serious jams.
- Curl: Prior to printing, labels must lie flat with no
more than 13 mm of curl in any direction.
- Condition: Do not use labels with wrinkles,
bubbles, or other indications of separation.
• Make sure that there is no exposed adhesive
material between labels. Exposed areas can cause
labels to peel off during printing, which can cause
paper jams. Exposed adhesive can also cause
damage to machine components.
• Do not run a sheet of labels through the machine
more than once. The adhesive backing is designed
for only a single pass through the machine.
• Do not use labels that are separating from the
backing sheet or are wrinkled, bubbled, or otherwise
damaged.
Card stock or
custom-sized
materials • Do not print on media smaller than 76 mm wide or
127 mm long.
• In the software application, set margins at least
6.4 mm away from the edges of the material.
Transparencies • To avoid damaging the machine, use only
transparencies designed for use in laser printers.
• Transparencies used in the machine must be able
to withstand 180 °C, the machine’s fusing
temperature.
• Place them on a flat surface after removing them
from the machine.
• Do not leave them in the paper tray for long periods
of time. Dust and dirt may accumulate on them,
resulting in spotty printing.
• To avoid smudging caused by fingerprints, handle
them carefully.
• To avoid fading, do not expose printed
transparencies to prolonged sunlight.
• Ensure that transparencies are not wrinkled, curled,
or have any torn edges.
• Do not use transparencies that separates from the
backing sheet.
• To prevent trancsparencies from sticking to each
other, do not leave the printed sheets stack up as
they are printed out.
