2. Printing Methods

Note
• If the DL size double flap envelope is creased after printing, choose DL Long Edge in Paper Size, from
the Basic tab. Put a new DL size double-flap envelope in the MP tray with the longest edge of the envelope
in first, then print again.
• When you put paper in the MP tray, remember the following:
• Put the leading edge (top of the paper) in first and push it gently into the tray.
• Make sure that the paper is straight and in the proper position in the MP tray. If it is not, the paper may
not be fed properly, resulting in a skewed printout or a paper jam.
