Envelopes that have double side seams Double-side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style can be more likely to wrinkle. Be sure that the seam extends all the way to the corner of the envelope as illustrated below. Acceptable Figure 5. Note Unacceptable Envelopes with double side seams Envelopes that have adhesive strips or flaps Envelopes that have a peel-off adhesive strip or more than one flap that folds over to seal must use adhesives that are compatible with the heat and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or jams. Envelope margins The following table shows typical address margins for a Commercial #10 or DL envelope. Table 11. Envelope margins Type of address Top margin Return address 15 mm (0.6 inch) Delivery address 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. 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, the envelope might wrinkle during printing. 30 Printer description Q1860-90918
