Gray areas on envelopes
Wrinkling
Wrinkles that form in envelopes after printing usually are caused by
the following envelope conditions:
Cause Action(s)
Envelope has seams or multiple
layers.
l Avoid printing over seams or other
multiple layer areas.
The toner density setting in the
printing software might be too
light.
l Reduce background (gray shading in
non-imaged areas) by adjusting the
toner density setting of the print to a
darker setting. See the
documentation that came with your
printer.
Cause Action(s)
Loose envelope construction. l Try different envelopes that are better
constructed. See "Envelope
construction" for characteristics of
good envelope construction.
Folds are not sharply creased.
l Try different envelopes that are better
constructed. See "Envelope
construction" for characteristics of
good envelope construction.
Low weight/low strength paper
used in envelope construction.
l Try different envelopes that are better
constructed. See "Envelope
construction" for characteristics of
good envelope construction.
High moisture content.
l You may need to acclimate the
envelope to your environment to
diminish differences in heat and
moisture. See "Conditioning print
media".
