For more information, refer to the Card Stock & Labels Guide, which is available from Lexmark. Transparency Guidelines The printer can print directly on transparencies specifically designed for use in laser printers. Print quality and durability depend on the transparency used. You should try samples of any transparencies you are considering using with the printer before buying large quantities. We recommend the Lexmark Optra 1200 dpi Laser Printer transparency, part number 1402809 (A4-size sheets) or 1402810 (letter-size sheets). The Paper Type setting should be set to Transparency to prevent jams. See page 64. The laser printing process heats transparencies to a temperature of 212oC (414oF) when Paper Type is not set to Transparency. If you select Transparency as your Paper Type, the printer heats the transparencies to a temperature of 180oC (356oF). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. Check with the manufacturer or vendor to determine whether the transparencies are usable with laser printers that heat transparencies to 180oC (356oF) or 212oC (414oF). Transparencies can be fed automatically from all standard and optional trays for all printer models and from the multipurpose feeder on the Optra S 1855, Optra S 1625 or Optra S 1255. Be careful when you handle transparencies. Fingerprints on the surface of the transparency cause poor print quality. Using Print Materials 139
