Envelopes

2

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 be fed from manual feed slot 
one at a time. 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 0.6 in. (15 mm) of the edges of 
envelopes.
