Selecting Paper and Media
The leading edge of an envelope that feeds into the
printer must be straight. The fold must be firmly
creased and be no thicker than two paper thick-
nesses. As a rule, the larger the envelope is, the
more difficult it is to feed properly.
The base weight of envelope paper must be 75 g/m
(20 pounds). Commercial envelopes, called regular
or business envelopes, are the most widely used and
are probably the most reliable for your printing
needs.
Neither envelopes with peel-off adhesive strips nor
envelopes that are heavily embossed feed well.
Avoid heavily textured or coated envelopes. In
addition, avoid
envelopes with snaps, clasps, tie strings, cello-
phane windows, or curved or thick leading paper
edges. (They don't feed consistently.)
envelopes composed with glues, inks, and
adhesives that could discolor, scorch, or melt
when heat is applied.
adhesives that generate harmful emissions at
temperatures greater than 200˚ C (392˚ F ) for 0.1
second.
envelopes made with recycled paper.
envelopes that use an adhesive that relies on
pressure for sealing.
envelopes that have already been through the
printer once. (Don't feed envelopes into the
printer a second time.)
envelope seams that do not have a continuous
and even glue line (excluding the envelope flap).
