4061-xx0 Transparencies You can feed transparencies from the standard tray (250-sheet tray for the T111 or 500-sheet tray for the T112), optional 250- or 500-sheet trays, or the multipurpose feeder. Try a sample of any transparencies you are considering using with the printer before buying large quantities. When printing on transparencies: • Be sure to set the Paper Type to Transparency from the printer driver or the Local Printer Setup Utility to avoid damaging your printer. • Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures of 225°C (437°F) without melting, discoloring, offsetting or releasing hazardous emissions. • To prevent print quality problems, avoid getting fingerprints on the transparencies. • Before loading transparencies, fan the stack to prevent sheets from sticking together. Selecting transparencies The printer can print directly on transparencies designed 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. The Paper Type setting should be set to Transparency to help prevent jams. Check with the manufacturer or vendor to determine whether your transparencies are compatible with laser printers that heat transparencies to 225°C (437°F). Use only transparencies that are able to withstand these temperatures without melting, discoloring, offsetting, or releasing hazardous emissions. For detailed information, refer to the Card Stock & Label Guide, which is available on the Lexmark Web site at www.lexmark.com. Transparencies can be fed automatically from the multipurpose feeder and all standard and optional trays, except the 2000-sheet drawer. Be careful when you handle transparencies. Fingerprints on the surface of the transparency cause poor print quality. Envelopes You can load up to 10 envelopes in the multipurpose feeder and 85 envelopes in the envelope feeder. Try a sample of any envelopes you are considering using with the printer before buying large quantities. When printing on envelopes: • To achieve the best possible print quality, use only high-quality envelopes that are designed for use in laser printers. • Set the Paper Size/Type in the Paper Menu to MP Feeder, Manual Env, or Env Feeder depending on the source you are using, set the paper type to Envelope, and select the correct envelope size from the operator panel, the printer driver, in the Local Printer Setup Utility, or from MarkVision™. • 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 multipurpose feeder or 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 new, undamaged envelopes. 1-16 Service Manual
