Note:
❏ If you do not load envelopes in the multipurpose feeder (MPF) right after they have been removed
from the packaging, they may bulge. To avoid jams, flatten them as shown below when loading them
in the multipurpose feeder (MPF).
❏ If envelopes are still not fed correctly, add some bending to the flap of the envelopes as shown in the
following illustration. The amount of the bending shall be 5 mm (0.20 inches) or less.
❏ To confirm the correct orientation of each print media such as envelopes, see the instruction on the
Envelope/Paper Setup Navigator on the print driver.
