Transparencies
For best results, use the following Lexmark transparencies:
These transparencies are designed to provide optimal print quality. Using other transparencies
designed for laser printers may yield unpredictable results and possibly cause damage to your printer.
Transparencies must be able to withstand temperatures of 175°C (347°F) without melting, discoloring,
offsetting, or releasing hazardous emissions.
To order transparencies in the U.S., call 1-800-438-2468. In other countries, see Contacts for
supplies information for a list of phone numbers or visit www.Lexmark.com on the World Wide web.
Black and white transparencies print at approximately 4 ppm and color transparencies print at
approximately 3 ppm. For transparency loading instructions, see Loading transparencies.
Envelopes
You can load up to 10 envelopes in tray 1. Load envelopes with the flap side down with the return
address positioned to enter the printer first. Do not load stamped envelopes. Load envelopes only in
tray 1. Before loading envelopes, fan the stack to prevent them from sticking together. For envelope
loading instructions, see Loading envelopes.
To ensure the best print quality, set Paper Type to Envelope and select the correct envelope size before
sending the job to print.
When printing on envelopes:
Try a sample of any envelopes you are considering using before buying large quantities.
Use envelopes made from 90 to 105 g/m

Use envelopes that can withstand temperatures of 175°C (347°F) without sealing, excessive
curling, wrinkling, or releasing hazardous emissions.
