Printing on envelopes
Use one of the following methods to print on envelopes.
● To print on one envelope
● To print on multiple envelopes
To print on one envelope
Use only envelopes that are recommended for laser printers. See Device media specifications
for more information.
Note Use the priority input tray for printing on one envelope. Use the media input tray for printing on
multiple envelopes.
1. To prevent the envelope from curling as it exits the printer, open the straight-through
output door.
2. Before loading the envelope, slide the media guides outward so that they are slightly
wider than the envelope.
3. If the envelope has a flap that folds along the long edge, place the flap-fold edge to the
left, with the side to be printed on facing up. If the envelope has a flap that folds along the
short edge, feed that edge into the device first, with the side to be printed on facing up.
