You can
print on plain paper envelopes in this size: No. 10
(4.1 × 9.5 inches [105 × 241 mm]).
If your product has two paper cassettes, you can load No. 10
size envelopes in Cassette 1 only.
Close
the paper stopper and output tray, if necessary.
Pull out
the paper cassette.
Slide
the edge guides outward.
Load
envelopes printable side down and flap edge right as shown.
Slide
the edge guides against the envelopes, but not too tightly.
Note: Make sure
the envelopes are loaded against the edge guide and not sticking
out from the end of the cassette.
Caution:
To prevent paper feeding problems, make sure
you do not load too many envelopes in the cassette.
Gently
insert the paper cassette.
Note: The
envelopes may slide forward slightly as you insert the cassette.
This is normal.
Extend
the output tray and open the paper stopper.
Always follow these paper loading guidelines:
If you have
trouble loading a stack of envelopes, press each envelope flat
before loading it or load one envelope at a time.
If print quality
declines when printing multiple envelopes, try loading one envelope
at a time.
Do not load
envelopes that are curled, folded, or too thin.
