Envelopes
Most envelopes will be suitable for your
machine. However, some envelopes may
have feed and print-quality problems
because of the way they have been made. A
suitable envelope should have edges with
straight, well-creased folds and the leading
edge should not be thicker than two sheets of
paper. The envelope should lie flat and not be
of baggy or flimsy construction. You should
buy quality envelopes from a supplier who
understands that you will be using the
envelopes in a laser machine.
Envelopes can only be fed from the MP tray.
Do not print envelopes using duplex printing.
We recommend that you print a test envelope
to make sure the print results are what you
want before you print or purchase a large
quantity of envelopes.
Check the following:
 Envelopes should have a lengthwise
sealing flap.
 The sealing flaps should be folded crisply
and correctly (irregularly cut or folded
envelopes may cause paper jams).
 Envelopes should consist of two layers of
paper in the area circled in figure below.

 Envelope joints that are sealed by the
manufacturer should be secure.
We recommend that you do not print

within 15 mm of the edges of envelopes.
