2"5. E NVELOPESPECIF!CATIONS
General
A wide varie~ of envelopes have been tested and most have performed acceptably. However, some
envelopes til not feed through the printer because of their construction. A suitable envelope
shotid have not more than two thicknesses of paper along the leading edge (the edge that enters
the printer fir~ see Figure 2-3) and the lmdlng edge should be straight with a sharp, well-creased
fold. ~lmsy envelopes lacking stiffness or those having curved leading edges fi not retiably feed
into the printer. Nso, envelopes having "baggy" construction may writie w~e going through the
printer's fnser. Poor resdts dso occur when envelopes are folded smaller than normal, musing a
thick leading edge near a corner. The folding accuracy of some manufacturers' envelopes may vary
enough to cause some envelopes to feed well and other, apparently similar, envelopes to jam.
Note
The Face Up (rear) Output Tray - the most direct path for envelopes and other
n
media - should be used to reduce wrin~lng and curl.
Envelope Procurement Recommendations
Purchase qudi~ envelopes only from a supplier who understands that the envelopes will be used
in a laser printer. Envelopes should lie flat, have folds that are consistent and sharp, and be
packaged in a protective box. Envelope samples should be tested before purchasing.
Consistent, long-term performance requires quality control from the envelope manufacturer and
proper handling until use. Envelopes should be stored where they m he flat and the edges will
not be damaged. They should be kept away from efiremes in temperature and humidi~ and
should be allowed to reach room temperature before use.
