Understanding paper and specialty media guidelines
Envelopes
You can load up to 10 envelopes in the multipurpose feeder and 85 envelopes in the envelope drawer. Try a sample of any
envelopes you are considering using with the MFP 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 Size/Type in the Paper menu to MP Feeder, Manual Env, or Env Feeder depending on the source
you are using. Set the paper type to Envelope, and select the correct envelope size from the control panel, the
MFP driver, or from MarkVision.
• For best performance, use envelopes made from 75 g/m
2
(20 lb bond) paper. You can use up to 105 g/m
2
(28 lb
bond) weight for the multipurpose feeder or 105 g/m
2
(28 lb bond) weight for the envelope feeder 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 230°C (446°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.
• Load only one size of envelope at a time in the envelope feeder.
• A combination of high humidity (over 60%) and the high printing temperatures may seal the envelopes.
