Envelopes You can print many types of envelopes with your printer. Some envelope styles perform better than others because their construction is better suited to laser printing. Envelope Construction Envelope construction is very critical. Envelope fold lines can very considerably, not only between manufacturers but also within a box from the same manufacturer. Successful printing on envelopes is very dependent upon the quality of the media. • Weight: The weight of the envelope paper should not exceed 28 lb (105 g/m2) or jamming may result. • Construction: Envelopes should lie flat with less than 0.25 in (6 mm) curl. • Manufacture: Make sure envelopes are not wrinkled, nicked, or otherwise damaged. • Sizes: Use only envelopes within the following sizes: Tray 1 • Minimum: 3.5 x 6.3 in (90 mm x 160 mm) • Maximum: 8.5 x 14.0 in (216 mm x 356 mm) Envelope Feeder • Minimum: 3.5 x 6.3 in (90 mm x 160 mm) • Maximum: 7.0 x 10.0 in (178 mm x 254 mm) Double Side Seam Envelopes Double side seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style generally performed adequately in Hewlett-Packard testing, but may be more likely to wrinkle. 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 fusing rollers in the printer. The extra flaps and strips may result in wrinkling or creasing, and may cause jamming. A-6 Media Specifications EN
