• 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 (about 170°C
(338 °F)). 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.

Transparency
To avoid damaging the machine, use only transparencies designed
for use in laser printers.
• Must withstand the machine's fusing temperature.
• Place them on a flat surface after removing them from the
machine.
• Do not leave unused transparencies in the paper tray for long.
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.
