Envelopes You can load up to 9 envelopes in the multipurpose feeder. Load envelopes with the flap side up with the return address posi- tioned to enter the printer last. Do not load stamped envelopes. Refer to the Setup Guide for additional loading instructions.

To ensure the best print quality, set Paper Type to Envelope and select the correct envelope size before sending the job to print.

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.
