Envelope Specifications
Choose envelopes that are well-constructed. They should lay flat and be
sharply creased. They should not be wrinkled, nicked, or otherwise
damaged.
Envelopes must use adhesives compatible with the heat and pressure of
the printer’s fusing process.
CAUTION
To prevent severe printer damage use only well-constructed envelopes
with sharp, well creased folds and no more than two thicknesses of
paper at the edge.
•• DO NOT use envelopes with clasps and snaps.
•• DO NOT use envelopes with windows, coated linings, self-stick
adhesives, or other synthetic materials.
•• DO NOT use damaged or poorly made envelopes.
