Use only new envelopes.
To optimize performance and minimize jams, do not use envelopes that:
Tips on using envelopes
Print samples on the envelopes being considered for use before buying large quantities. When printing on envelopes:
Use envelopes designed specifically for laser printers. Check with the manufacturer or vendor to ensure the envelopes can withstand temperatures up to 210°C (410°F) without sealing, wrinkling, curling excessively, or releasing hazardous emissions.
Note: Envelopes can be printed at a temperature up to 220°C (428°F) if Envelope Weight is set to Heavy and Envelope Texture is set to Rough. Select these settings using the Embedded Web Server, or from the printer control panel Paper menu.
For the best performance, use envelopes made from 90 g/m2 (24 lb bond) paper. Use up to 105 g/m2 (28 lb bond) weight for envelopes as long as the cotton content is 25% or less. All-cotton envelopes must not exceed
90 g/m2 (24 lb bond) weight.
Before loading transparencies, fan the stack to prevent sheets from sticking together.
To prevent print quality problems, avoid getting fingerprints on the transparencies.
We recommend Lexmark part number 70X7240 for letter-size transparencies and Lexmark part number 12A5010 for A4-size transparencies.
Tips on using transparencies
Print samples on the transparencies being considered for use before buying large quantities. When printing on transparencies:
Feed transparencies from the standard 250-sheet tray or the multipurpose feeder.
Use transparencies designed specifically for laser printers. Check with the manufacturer or vendor to ensure transparencies are able to withstand temperatures up to 175°C (350°F) without melting, discoloring, offsetting, or releasing hazardous emissions.
Note: Transparencies can be printed at a temperature up to 180°C (356°F) if Transparency Weight is set to Heavy and Transparency Texture is set to Rough. Select these settings using the Embedded Web Server, or from the printer control panel Paper menu.
