How should I load envelopes?

• See below.

  Loading Envelopes

  You can print on plain paper envelopes in this size: No. 10 (4.1 × 9.5 inches [105 × 241 mm]).
  1. Flip the feeder guard forward.
      
     
  2. Pull up the paper support and its extension.
  3. Pull out the output tray and open the paper stopper.
      
     
  4. Slide the edge guide left.
      
     
  5. Load up to 10 envelopes printable side up and flap edge left, against the right side as shown.
  6. Slide the edge guide against the envelopes, but not too tightly.
      
     
  7. Flip the feeder guard back.
  Always follow these envelope 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.
  • Do not load envelopes above the arrow mark inside the edge guide.
  • Do not load envelopes that are curled, folded, or too thin, or that have plastic windows or exposed adhesive flaps.
