Envelopes with 100% cotton content must not exceed 90 g/m2 (24 lb bond) weight. Use only new, undamaged envelopes. For best performance, do not use envelopes that: Have excessive curl or twist Are stuck together or damaged in any way Contain windows, holes, perforations, cutouts, embossing Use metal clasps, string ties, or metal folding bars Have an interlocking design Have postage stamps attached Have any exposed adhesive when the flap is in the sealed or closed position Have nicked edges or bent corners Have rough, cockle, or laid finishes Use envelopes that can withstand temperatures of 205°C (401°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions. If you have any doubts about the envelopes you are considering, check with the envelope supplier. Adjust the width guide to fit the width of the envelopes. To load envelope in the multipurpose feeder, insert the envelopes with the flaps closed and the shortedge of the envelopes facing into the printer. The print side must be facing down. See "Loading the Multipurpose Feeder" for instructions on loading an envelope. Use one envelope size during a print job. Make sure the humidity is low because high humidity (more than 60%) and the high printing temperatures may seal the envelopes. Labels Your printer can print on many labels designed for use with laser printers. Label adhesives, face sheet (printable stock), and topcoats must be able to withstand temperatures of 205°C (401°F) and pressure of 25 pounds per square inch (psi). Before buying large quantities of any print media, Dell recommends trying a sample first. When printing on labels: Set the paper type to Label in the Tray Settings. Set the paper type to Label from the printer driver. Do not load labels together with paper or transparencies in the same tray. This may result in a jam.
