How should I load envelopes?

• See below.

  Loading Envelopes in the Cassette

  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.
  1. Close the paper stopper and output tray, if necessary.
     
     
  2. Pull out the paper cassette and remove the paper cassette cover.
     
     
  3. Slide the edge guides outward.
     
     
  4. Load envelopes printable side down and flap edge right as shown.
     
     

     Caution:
     To prevent paper feeding problems, make sure you do not load too many envelopes in the cassette.

  5. 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.

  6. Close the paper cassette cover and gently insert the paper cassette.
     
     

     Note: The envelopes may slide forward slightly as you insert the cassette. This is normal.

  7. When prompted by the product's LCD screen, select Envelope #10 for the Paper Size and Envelope for the Paper Type, and select OK.
  8. Extend the output tray and open the paper stopper.
     
     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.
     • 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.
     • Do not load envelopes that have adhesive surfaces.
     • Do not load envelopes that have windows.

  Loading Paper and Envelopes in the Rear Feed Slot

  You can load one envelope or one sheet of paper or card stock in the rear feed slot.
  1. Send your print job before loading paper into the rear feed slot.
  2. Extend the output tray and open the paper stopper.
     
     

     Note: If you are using legal-size or longer paper, do not open the paper stopper.

  3. Open the rear paper feed slot and push it back.
     
     
  4. Slide out the edge guides.
     
     
  5. Do one of the following:
     • Load one sheet of paper with the printable side faceup and slide the edge guides against the paper, but not too tightly.
       
       
     • Load one envelope short edge first, with the flap facing down and the flap edge to the right.
       
       
  6. Insert the paper or envelope into the slot until the printer feeds it automatically.
     
     
  Always follow these paper loading guidelines:
  • Load only one sheet or one envelope at a time.
  • Load paper short edge first, no matter which way your document faces.
  • Load the printable side faceup.
  • Load letterhead or pre-printed paper top edge first.
  • Check the paper package for any additional loading instructions.
  • Do not load envelopes that are curled, folded, or too thin.
  • Do not load envelopes that have adhesive surfaces.
  • Do not load envelopes that have windows.

  Note: You can load a sheet of binder paper with holes on one of the long edges, but not for automatic 2-sided printing.
