Envelope construction
Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the
following components:
●
Weight: See
for supported envelope weight.
●
Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.3 inch) curl
and should not contain air. (Envelopes that trap air can cause problems.)
●
Condition: Make sure envelopes are not wrinkled, nicked, or otherwise damaged.
●
Sizes in Tray 1: See
Supported sizes of paper for input and output
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip, or with more than one flap that folds over to seal, must
use adhesives compatible with the heat and pressure of the MFP. The extra flaps and strips
might cause wrinkling, creasing, or jams.
Envelopes with double-side-seams
Double-side-seam construction has vertical seams at both ends of the envelope rather than
diagonal seams. This style might be more likely to wrinkle. Make sure the seam extends all the
way to the corner of the envelope.
Envelope storage
Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored
flat. If air is trapped in an envelope creating an air bubble, then the envelope can wrinkle during
printing.
Card stock and heavy paper
For optimum product performance, do not use paper heavier than 216 g/m
2
(58 lb bond) in
Tray 1 or 199 g/m
2
(53 lb bond) in other trays. Paper that is too heavy might cause misfeeds,
stacking problems, jams, poor toner fusing, poor print quality, or excessive mechanical wear.
Card stock construction
●
Smoothness: 135 to 216 g/m
2
(36 to 58 lb bond) card stock should have a smoothness
rating of 100 to 180 Sheffield.
●
Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.
●
Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged.
●
Sizes: See the sizes listed for
