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. Be sure the seam extends all the way to the corner of the envelope as illustrated below. NOTE 1 2 1 Acceptable envelope construction 2 Unacceptable envelope construction 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 in the printer. The extra flaps and strips might cause wrinkling, creasing, or even jams and might even damage the fuser. Envelope margins The following gives typical address margins for a commercial #10 or DL envelope. Type of address Return address Delivery address Top margin 15 mm (0.6 inch) 51 mm (2 inches) Left margin 15 mm (0.6 inch) 89 mm (3.5 inches) For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges of the envelope. Avoid printing over the area where the envelope's seams meet. Envelope storage Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing. For more information, see Printing envelopes. 238 Appendix C Specifications ENWW
