  Loading Paper in the Cassette

  You can load paper up to this size in the paper cassette: Legal (8.5 × 14 inches [216 × 356 mm]).

  Note: Before loading paper, make sure your product is not currently printing.

  1. Open the paper cassette cover.
     
     
  2. Pull out the paper cassette until it stops.
     
     

     Note: You cannot remove the paper cassette.

  3. Slide the edge guides outward.
     
     
  4. Do one of the following:
     • Insert paper into the cassette with the printable side facedown and slide it in until it stops.
       
       

       Note: Make sure the paper is loaded against the rear of the cassette.

     • For legal-size paper, load paper using the guide line as shown.
       
       
     • For 8.5 × 13 inch (216 × 330 mm) paper, load paper using the guide line as shown.
       
       
     • Insert up to 10 envelopes with the printable side facedown and flap edge left, as shown.
       
       
  5. Slide the edge guides against the paper, but not too tightly.
     
     

     Note: Make sure the paper fits under the tabs on the edge guides.

  6. Slide the cassette back into the product until it stops.
  7. Do one of the following:
     • Close the paper cassette cover.
     • If you loaded envelopes, thick paper, or business cards, lower the output selector to eject paper to the front of the printer and leave the paper cassette cover open.
       
       

     Note: Do not remove or insert the paper cassette during printing.

     Always follow these paper loading guidelines:
     • Load only the recommended number of sheets.
     • Load paper short edge first and printable side facedown.
     • Load letterhead or pre-printed paper top edge first.
     • Make sure the paper fits under the tabs on the edge guides and does not stick out from the rear of the cassette.
     • 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 an envelope that is curled, folded, or too thin, or that has a plastic window.
     • Check the paper package for any additional loading instructions.
