Understanding paper and specialty media guidelines

– Have rough, cockle, or laid finishes.

•Use envelopes that can withstand temperatures of 230°C (446°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions. If you have any doubts about the envelopes you are considering using, check with the envelope supplier.

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

•Load only one size of envelope at a time.

•A combination of high humidity (over 60%) and the high printing temperatures may seal the envelopes.

Labels

The printer can print on many labels designed for use with laser printers, except for vinyl labels. These labels are supplied in letter size, A4 size, and legal size sheets. Label adhesives, face sheet (printable stock), and topcoats must be able to withstand temperatures of 230°C (446°F) and pressure of 25 pounds per square inch (psi).

Try a sample of any labels you are considering using with the printer before purchasing a large quantity.

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.

After printing approximately 10,000 pages of labels (or each time you replace the toner cartridge), complete the following steps to maintain printer feeding reliability:

1Print five sheets of paper.

2Wait approximately five seconds.

3Print five more sheets of paper. When printing on labels:

•Set the Paper Type menu item to Labels in the Paper menu. Set the Paper Type from the printer operator panel, the printer driver, or from MarkVision Professional.

•Do not load labels together with paper or transparencies in the same source; mixing media can cause feeding problems.

•Do not use label sheets with a slick backing material.

•Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also contaminate the printer and the cartridge with adhesive, and could void the printer and cartridge warranties.

•Use labels that can withstand temperatures of 230°C (446°F) without sealing, excessive curling, wrinkling, or releasing hazardous emissions.

•Do not print within 1 mm (0.04 in.) of the edge of the label, of the perforations, or between die-cuts of the label.

•Do not use label sheets that have adhesive to the edge of the sheet. Zone coating of the adhesive at least 1 mm (0.04 in.) away from edges is recommended. Adhesive material contaminates the printer and could void the warranty.

•If zone coating of the adhesive is not possible, remove a 3 mm (0.125 in.) strip on the leading and driver edge, and use a non-oozing adhesive.

•Remove a 3 mm (0.125 in.) strip from the leading edge to prevent labels from peeling inside the printer.

•Portrait orientation is preferred, especially when printing bar codes.

•Do not use labels that have exposed adhesive.
