Lexmark C500N User Manual page 25

• Use only new, undamaged envelopes.
• For best performance and to minimize jams, do not use envelopes that:
– Have excessive curl or twist
– Are stuck together or damaged in any way
– Contain windows, holes, perforations, cutouts, or embossing
– Use metal clasps, string ties, or metal 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 nicked edges or bent corners
– Have rough, cockle, or laid finishes
• Use envelopes that can withstand temperatures of 170°C (338°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions. If you have any doubts about the envelopes you are considering using, check with
the envelope supplier.
• Adjust the width guide to fit the width of the envelopes.
• Load only one size of envelope at a time in the tray. Envelopes may only be loaded in the standard tray. Load them
with the flap down and the flap to the left of the tray.
• A combination of high humidity (over 60%) and the high printing temperatures may seal the envelopes.
• Use only envelopes with a flap that covers where the seams come together. For examples, see below.
