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 MFP. The extra flaps and strips might cause
wrinkling, creasing, or even jams and might even damage the fuser.
Envelope margins
The following gives typical address margins for a commercial #10 or DL envelope.
Type of address Top margin Left margin
Return address 15 mm (0.6 inch) 15 mm (0.6 inch)
Delivery address 51 mm (2.0 inches) 89 mm (3.5 inches)
NOTE For the best print quality, position margins no closer than 15 mm (0.6 inch) 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 might wrinkle during printing.
For more information, see Envelopes .
Labels
CAUTION To avoid damaging the MFP, use only labels recommended for laser printers. Never
print on the same sheet of labels more than once or print on a partial sheet of labels.
Label construction
When selecting labels, consider the quality of each component:
● Adhesives: The adhesive material should be stable at 200°C (392°F), the MFP'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 13 mm (0.5 inch) of curl in any direction.
● Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
For more information, see Labels .
NOTE Choose labels in the printer driver.
Transparencies
Transparencies used in the MFP must be able to withstand 200°C (392°F), the MFP's fusing
temperature.
