Tips on using envelopes

• From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the envelopes loaded in the tray.
• Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed specifically for laser printers.
• For best performance, use envelopes made from 90‑g/m² (24‑lb) paper or 25% cotton.
• Use only new envelopes from undamaged packages.
• To optimize performance and minimize jams, do not use envelopes that:
• Have excessive curl or twist.
• Are stuck together or damaged in any way.
• Have windows, holes, perforations, cutouts, or embossing.
• Have metal clasps, string ties, or folding bars.
• Have an interlocking design.
• Have postage stamps attached.
• Have any exposed adhesive when the flap is in the sealed or closed position.
• Have bent corners.
• Have rough, cockle, or laid finishes.
• Adjust the width guides to fit the width of the envelopes.
• Before loading the envelopes on the tray, flex and fan the envelopes to loosen them. Straighten the edges on a level surface.

Note:  A combination of high humidity (over 60%) and high printing temperature may wrinkle or seal envelopes.
