When printing on transparencies:
• Feed transparencies from the standard 250‑sheet tray or the manual feeder.
• Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure
transparencies are able to withstand temperatures up to 190°C (374°F) without melting, discoloring, offsetting, or
releasing hazardous emissions.
Note: Transparencies can be printed at a temperature up to 200°C (392°F) if Transparency Weight is set to
Heavy and Transparency Texture is set to Rough. If the transparencies you are using can withstand that
temperature, select those settings using the Embedded Web Server, or from the printer control panel Paper
menu.
• 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 70X7240 for letter‑size transparencies and Lexmark part number 12A5010
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:
• Load envelopes from the manual feeder.
• Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the
envelopes can withstand temperatures up to 210°C (410°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 or 25% cotton bond. 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.
• The minimum supported weight for envelopes is 75 g/m
2
(20 lb bond). For non‑peel strip, self‑seal envelopes, the
minimum supported weight is 80 g/m
2
(21 lb bond).
• 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
– 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.
