When printing on transparencies:
• Feed transparencies from any tray or drawer, except the Optional 2,000-sheet tray.
• Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure
transparencies are able to withstand temperatures up to 170°C (338°F) without melting, discoloring, offsetting,
or releasing hazardous emissions.
• To prevent print quality problems, avoid getting fingerprints on the transparencies.
• Before loading transparencies, fan the stack to prevent sheets from sticking together.
• We recommend Lexmark part number 12A8240 for letter-size transparencies and Lexmark part number 12A8241
for A4-size transparencies.
Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities.
When printing on envelopes:
• Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the
envelopes can withstand temperatures up to 190°C (374°F) without sealing, wrinkling, curling excessively, or
releasing hazardous emissions.
• For the best performance, use envelopes made from 90 g/m
2
(24 lb bond) paper. Use up to 105 g/m
2
(28 lb bond)
weight for envelopes as long as the cotton content is 25% or less. All-cotton envelopes must not exceed
90 g/m
2
(24 lb bond) weight.
• Use only new envelopes.
• 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 the high printing temperature may wrinkle or seal envelopes.
Tips on using labels
Print samples on the labels being considered for use before buying large quantities.
Note: Paper labels are supported. Other media such as vinyl may show print quality defects in some environments,
and prolonged vinyl label usage may reduce fuser life.
For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on
the Lexmark Web site at www.lexmark.com/publications.
