Media specifications
When printing on transparencies:
• Be sure to set the Paper Type to Transparency from the printer operator panel, printer driver, or from MarkVision™
Professional.
• Use transparencies designed specifically for laser printers. Transparencies must be able to withstand
temperatures of 180°C (356°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.
Selecting transparencies
The printer can print directly on transparencies designed for use in laser printers. Transparencies must be 0.12–0.14 mm
(4.8–5.4 mil) in thickness or 161–179 g/m
2
in weight. Print quality and durability depend on the transparency used. Always
print samples on the transparencies being considered for use before buying large quantities.
We recommend Lexmark part number 12A8240 for letter size transparency and Lexmark part number 12A8241 for A4 size
transparency.
The Paper Type setting should be set to Transparency to help prevent jams. (See “Paper Type” on the Publications CD for
detailed information about this setting.) Check with the manufacturer or vendor to determine whether the transparencies are
compatible with laser printers that heat transparencies to 180°C (356°F). Use only transparencies that are able to withstand
these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions.
Envelopes
Try a sample of any envelopes in consideration for use with the printer before buying large quantities. See Loading the
multipurpose feeder for instructions on loading envelopes.
When printing on envelopes:
• To achieve the best possible print quality, use only high-quality envelopes that are designed for use in laser
printers.
• Set the Paper Source in the Paper Menu based on the source in use, set the Paper Type to Envelope, and
select the correct envelope size from the operator panel, the printer driver, or from MarkVision Professional.
• For 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. Envelopes with 100% cotton content must not
exceed 90 g/m
2
(24 lb bond) weight.
• 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 180°C (356°F) without sealing, excessive curling, wrinkling, or
releasing hazardous emissions. If any doubts exist about the envelopes considered for use, check with the
envelope supplier.
• Adjust the width guide to fit the width of the envelopes.
• A combination of high humidity (over 60%) and the high printing temperatures may wrinkle or seal the envelopes.
