Note
• If envelopes get smudged during printing set the Media Type to Thick Paper or Thicker Paper to
increase the fixing temperature.
• If the envelopes are creased after they are printed, see Improving the print quality on page 154.
®
• (For Windows users) If DL size double flap envelopes are creased after printing, choose DL Long Edge
in Paper Size, from the Basic tab. Put a new DL size double-flap envelope in the manual feed slot with
the longest edge of the envelope in first, then print again.
• Envelope joints that are sealed by the manufacturer should be secure.
• All sides of the envelope should be properly folded without wrinkles or creases.
