When printing on envelopes:

•Try a sample of any envelopes you are considering using

with the printer before buying large quantities.

• Use envelopes made from 90 to 105 g/m2 (24 to 28 lb) bond paper. For best performance and fewer paper jams, do not use envelopes that:

–Have excessive curl

–Are stuck together

–Are damaged in any way

–Contain windows, holes, perforations, cutouts, or embossing

–Use metal clasps or string ties

–Have postage stamps attached

–Have any exposed adhesive when the flap is in the sealed or closed position

•Use envelopes that can withstand temperatures of 195°C

(383°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions.

• Adjust the left paper guide to fit the envelope width.
