Before loading envelopes, press them down to make sure that all air is
removed, and make sure that the folds of the flaps are firmly pressed,
otherwise the envelopes may become wrinkled or a paper misfeed may
occur.
When loading envelopes, load them with the flap side up, as shown in the
illustration. If the envelopes are loaded with the flap side down, a paper
misfeed may occur. The flap side of envelopes cannot be printed on.
A maximum of 10 envelopes can be loaded into the bypass tray.
