Printing on Envelopes
CAUTION
Before you load envelopes in Tray 1, 
make sure they are undamaged and are 
not stuck together. Never use envelopes 
with clasps, snaps, windows, coated 
linings, self-stick adhesives, or other 
synthetic materials. For more 
information, see Media Specifications.
1
Open Tray 1 by pulling the front 
cover down. 
2
Open the rear output bin by pulling 
down on the top section of the bin. 
Slide out the extender until it 
extends fully. 
Note
Using the rear output bin reduces 
envelope curl.
3
Slide the width guides on Tray 1 
outward slightly wider than the 
media.

4
Place the envelopes into the tray 
short-edge in, print-side up. The 
stamp end must enter the printer 
first. 
5
Slide the width guides inward until 
they lightly touch the envelope stack 
without bending it. The envelopes 
should be centered between the 
paper guides and under the tabs on 
the paper width guides. 
Note
If the envelope has a flap on the short 
edge, this edge must enter the printer 
first.
You may experience some paper jams 
when using any media with a length 
less than 178 mm (7 in.). This may be 
caused by paper that has been affected 
by environmental conditions. For 
optimum performance, make sure you 
are storing and handling the paper 
correctly (see Printing and Paper 
Storage Environment). Using media 
from another manufacturer may 
also help.
