1 Acceptable envelope construction
2 Unacceptable envelope construction
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 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 15mm (0.6inch) 15mm (0.6inch)
Delivery address 51mm (2.0inches) 89mm (3.5inches)
NOTE For the best print quality, position margins no closer than 15mm (0.6inch) 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 Printing and paper-storage environment .
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.
