Depending on the choice of envelopes, it is possible to expect variable levels of light wrinkling. It is recommended that you try a sample first before buying large quantities of any print media. See "Loading Print Media" for instructions on loading an envelope. When printing on envelopes: Use only high-quality envelopes that are designed for use in laser printers. Set the print media source to the MPF or tray 1. Set the paper type to Envelope, and select the correct size of envelope from the printer driver. For best performance, use envelopes made from 75 g/m2 (20 lb bond) paper. You can use up to 105 g/m2 (28 lb bond) weight for the envelope feeder as long as the cotton content is 25% or less. Envelopes with 100% cotton content must not exceed 90 g/m2 (24 lb bond) weight. Use only freshly unpacked, undamaged envelopes. 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 guide to fit the width of the envelopes. To load envelope in the MPF, insert the envelopes with the flaps closed and the short-edge of the envelopes facing into the printer. The print side must be facing down. See "Loading Print Media in the MPF" for instructions on loading an envelope. Use one envelope size during a print job. Ensure the humidity is low because high humidity (more than 60%) and the high printing temperatures may seal the 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 NOTE: You can load envelopes also on the tray 1. For more information, see "Loading an Envelope in Standard Trays ." 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). It is recommended that you try a sample first before buying large quantities of any print media. When printing on labels: Set the paper type to Label from the printer driver. Do not load labels together with paper in the same tray. This may result in a jam. Do not use label sheets with a slick backing material.
