Dell 1125 Mono Laser User's Guide - Page 19

Selecting Transparencies The printer is designed to print directly on transparencies manufactured for use in laser printers. Print quality and durability depend on the transparency used. Always print samples on the transparencies you are considering before buying large quantities. Check with the manufacturer or vendor to determine whether your transparencies are compatible with laser printers that heat transparencies to 180°C (356° F). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. NOTE: Dell recommends using 3M transparencies for the Dell MFP 1125. Envelopes Load one envelope at a time in the bypass tray. Try a sample of any envelopes you are considering using with the printer before buying large quantities. See Using the Bypass Tray for instructions on loading an envelope. When printing on envelopes: l To achieve the best possible print quality, use only high-quality envelopes that are designed for use in laser printers. l For best performance, use envelopes made from 75 g/m2 (20 lb bond) paper. You can use up to 90 g/m2 (24 lb bond) weight for the bypass tray as long as the cotton content is 25 percent or less. l Use only new, undamaged envelopes. l Use envelopes that can withstand temperatures of 180°C (356°F) without sealing, curling, wrinkling, or releasing hazardous emissions. If you have any doubts about the envelopes you are considering using, check with the envelope supplier. l Load an envelope with the flap side down and with the stamp area on the top left side. The end of the envelope with the stamp area enters the bypass tray first. See Using the Bypass Tray for instructions on loading envelopes. l Adjust the width guide to fit the width of the envelopes. l A combination of high humidity (over 60%) and the high printing temperatures may seal the envelopes. For best performance and to minimize jams, do not use envelopes that: l Have excessive curl or twist. l Are stuck together or damaged in any way. l Contain windows, holes, perforations, cutouts, or embossing. l Use metal clasps, string ties, or metal folding bars. l Have an interlocking design. l Have postage stamps attached. l Have any exposed adhesive when the flap is in the sealed or closed position. l Have nicked edges or bent corners. l Have rough, cockle, or laid finishes. Labels The printer is designed to print on many labels manufactured for use with laser printers. 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 180°C (356°F) and pressure of 25 pounds per square inch (psi). You should load only one label sheet at a time in the bypass tray. NOTE: Try a sample of any labels you are considering using with the printer before purchasing a large quantity. When printing on labels: l Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a jam. Partial sheets also contaminate your printer and your cartridge with adhesive, and could void your printer and cartridge warranties. l Use labels that can withstand temperatures of 180°C (356°F) without sealing, curling, wrinkling, or releasing hazardous emissions. l Do not print within 0.04 in. (1 mm) of the edge of the label, of the perforations, or between die-cuts of the label. l Do not use label sheets that have adhesive to the edge of the sheet. We recommend zone coating of the adhesive at least 0.04 in. (1 mm) away from edges. Adhesive material contaminates your printer and could void your warranty. l If zone coating of the adhesive is not possible, a 0.125 in. (3 mm) strip must be removed on the leading and driver edge, and a non-oozing adhesive used. l Remove a 0.125 in. (3 mm) strip from the leading edge to prevent labels from peeling inside the printer. l Portrait orientation is preferred, especially when printing bar codes. l Do not use labels that have exposed adhesive.
