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 the 250-sheet standard tray or 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 230°C (446°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.
•
Load only one size of envelope at a time in the tray. Envelopes may only be loaded in the
standard tray. Load them with the flap down and the flap to the left of the tray.
•
A combination of high humidity (over 60%) and the high printing temperatures may seal the
envelopes.
