CAUTION 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. 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.
