Manual feeder (duplex printing) Preprinted letterhead design is placed facedown. The top edge of the sheet with the
logo should enter the manual feeder last.
Note: Check with the manufacturer or vendor to determine whether the chosen preprinted letterhead is acceptable for
laser printers.
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 t he multipurpose feeder.
Use transparencies designed specifically for laser pr inters. Check with the manufacturer or v endor 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 set tings using the Embedded Web Server, or from t he
printer control panel Paper menu.
To prevent print quality problems, avoid getting fi ngerprints on the transparencies.
Before loading transparencies, fan the stack to p revent sheets from sticking together.
We recommend Lexmark part number 70X7240 for letter-size transpar encies and Lexmark part number 12A5010
for A4-size transparencies.
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 .
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 cont ent is 25% or less. All-cotton envelopes m ust not exceed
90 g/m2 (24 lb bond) weight.
Use only new envelopes.
To optimize performance and minimize jams, do not use envelopes that:
Have excessive curl or twist
Are stuck together or damaged in any way
