Print envelopes from optional tray 1 only. Send envelopes straight through the printer, entering at
optional tray 1 and exiting from the face-up bin.
For the best print quality, position margins no closer than 15 mm (0.6 in) from the edges of the
envelope. Avoid printing over the area where the envelope seams meet.
Envelopes with adhesive strips or flaps
Check to make sure that envelopes with peel-off adhesive strips, or with more than one flap that
folds over to seal, use adhesives compatible with the heat and pressure in the printer. The extra flaps
and strips might cause wrinkling, creasing, jams, and can even damage the fuser.
To avoid damaging the printer, use only labels recommended for laser printers. 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 190 degrees C (374 degrees F), which
is the printer fusing temperature.
Arrangement —Do not use labels that have exposed backing between them. Labels can peel off
sheets with spaces between the labels, causing jams.
Curl —Prior to printing, labels must lie flat with no more than 10 mm (0.39 in) of curl in any
Condition —Do not use labels that have wrinkles, bubbles, or other indications of separation.
Use only optional tray 1 to print labels. Send labels straight through the printer, entering at optional
tray 1 and exiting from the face-up bin.
