Do not use any of the following types of envelopes, as they will cause paper feed problems:

• Envelopes that are damaged, curled, wrinkled, or irregularly shaped
  
• Envelopes that are extremely shiny or highly textured
  
• Envelopes with clasps, snaps or tie strings.
  
• Envelopes with self-adhesive closures
  
• Envelopes of baggy construction
  
• Envelopes that are not sharply creased
  
• Embossed envelopes
  
• Envelopes that were previously printed by a laser printer
  
• Envelopes that are pre-printed on the inside
  
• Envelopes that cannot be arranged uniformly when placed in a pile
  
• Envelopes constructed with paper that exceeds the paper weight specifications for the printer.
  
• Poorly manufactured envelopes with edges that are not straight or consistently square.
  
• Envelopes with transparent windows, holes, cutouts or perforations.

• Do not load different types of paper at the same time in the paper cassette because paper jams and misfeeds may occur.
  
• Do not print on envelopes using 2-Sided(Duplex) printing.
  
• For correct printing, you must select the same paper size from within your software application as the paper in the tray.
  
• If your application software does not support paper size selection in its print menu, you can change the paper size on the printer's control panel under the PAPER menu.
