Envelopes that have been creased after they have been
printed:
At the back of the printer open the face-up output tray and
push down the blue tabs at the left-hand and right-hand sides
(as shown in the figure below). When you have finished
printing your envelopes, close the face-up output tray to reset
the blue tabs automatically. To reset the blue tabs manually,
push the blue tabs back to their original position.

Put the envelopes in the multi-purpose tray so they touch the
back of the tray and remain below the maximum paper mark
( ).
Make sure that the paper is neatly stacked and in the proper
position on the multi-purpose tray. If it is not, the paper may
not be fed properly, resulting in a skewed printout or a paper
jam.
