Tips on using transparencies
• Print a test page on the transparencies being considered for use before buying large quantities.
• Feed transparencies from the multipurpose feeder only.
• From the Paper menu, set the MP Feeder Type to Transparency.
• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures
of 230°C (446°F) without melting, discoloring, offsetting, or releasing hazardous emissions.
• To prevent print quality problems, avoid getting fingerprints on the transparencies.
• Before loading transparencies, flex the stack to prevent sheets from sticking together.
• We recommend Lexmark transparencies. For ordering information, see the Lexmark Web site at
www.lexmark.com.
Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
• Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure that the
envelopes can withstand temperatures up to 220°C (446°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
• For best performance, use envelopes made from 90‑g/m
2
(24‑lb bond) paper or 25% cotton. All‑cotton envelopes
must not exceed 70‑g/m
2
(20‑lb bond) weight.
• 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.
Note: A combination of high humidity (over 60%) and high printing temperature may wrinkle or seal envelopes.
