Note Envelopes 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: The weight of the envelope paper should not exceed 105 g/m2 (28 lb) or jamming might occur.
Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl, and should not contain air.
Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
Temperature: You should use envelopes that are compatible with the heat and pressure of the printer.
Size: You should use only envelopes within the following size ranges. Tray Tray 1 Minimum 76 by 127 mm (3 by 5 inches) Maximum 216 by 356 mm (8.5 by 14 inches) Use only tray 1 to print envelopes. You might experience some jams when using any media with a length less than 178 mm (7 inches). This might be caused by paper that has been affected by environmental conditions. For optimum performance, make sure you are storing and handling the paper correctly (see "Printing and paper storage environment" on page 138). Choose envelopes in the printer driver (see "Printing by type and size of media" on page 53). 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. Correct ENWW Incorrect 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. Media specifications 139
