Lexmark C935 manual Using envelopes, Using labels

•Use transparencies that are 0.12–0.14 mm (4.8–5.4 mil) in thickness or 161–179 g/m2 in weight. Print quality and durability depend on the transparencies used.

•To prevent print quality problems, avoid getting fingerprints on the transparencies.

•Before loading transparencies, fan the stack to prevent sheets from sticking together.

•We recommend Lexmark part number 12A8240 for letter-size transparencies.

Using envelopes

Print samples on the envelopes being considered for use before buying large quantities.

When printing on envelopes:

•From the control panel, set the Paper Source based on the source in use. From MarkVision Professional, Print Properties, or the control panel, set the Paper Type to Envelope, and select the envelope size.

•Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the envelopes can withstand temperatures up to 230°C (446°F) without sealing, wrinkling, curling excessively, or releasing hazardous emissions.

•For the best performance, use envelopes made from 90 g/m2 (24 lb bond) paper. Use up to 105 g/m2 (28 lb bond) weight for envelopes as long as the cotton content is 25% or less. All-cotton envelopes must not exceed 90 g/ m2 (24 lb bond) weight.

•Use only new envelopes.

•To optimize performance and minimize jams, do not use envelopes that:

–Have excessive curl or twist

–Are stuck together or damaged in any way

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

–Have metal clasps, string ties, or 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 bent corners

–Have rough, cockle, or laid finishes

•Adjust the width guide to fit the width of the envelopes.

Note: A combination of high humidity (over 60%) and the high printing temperature may wrinkle or seal envelopes.

Using labels

Print samples on the labels being considered for use before buying large quantities.

For detailed information on label printing, characteristics, and design, see the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com/publications.

When printing on labels:

•From MarkVision Professional, Print Properties, or the control panel, set the Paper Type to Labels.

•Use only letter, A4, or legal-size label sheets.

•Use labels designed specifically for laser printers. Check with the manufacturer or vendor to verify that label adhesives, face sheet (printable stock), and topcoats can withstand temperatures up to 230°C (446°F) and pressure up to 25 psi without delaminating, oozing around the edges, or releasing hazardous fumes. Do not use vinyl labels.

•Do not use labels with slick backing material.
