•
Use transparencies designed specifically for laser printers. Transparencies must be able to withstand temperatures
of 230°C (446°F) without melting, discoloring, offsetting, or releasing hazardous emissions.
•
To prevent print quality problems, avoid getting fingerprints on the transparencies.
•
Before loading transparencies, flex the stack to prevent sheets from sticking together.
•
We recommend Lexmark transparencies. For ordering information, see the Lexmark Web site at
