For guidance on the media you can use with your printer, 

which input tray and which ejection method to use, see the 

section entitled “Paper and tray information” in the 

“Specifications” chapter.

We recommends the following guidelines when selecting paper 

and envelopes for use in your printer:

• Paper and envelopes should be stored flat and away from 

moisture, direct sunlight and heat sources.

• Use a smooth finished paper such as copier or laser type 

paper with a Sheffield (smoothness) rating of 250 or 

less. If in doubt, please ask your paper supplier.

• Use envelopes designed for use in laser type printers.
• The use of heavily laid or textured paper will seriously 

affect the life of the image drum.

• Do not use very smooth, shiny/glossy paper.
• Do not use heavily embossed letterhead paper.
• Avoid printing on both sides and putting paper through 

the printer twice.

• Avoid using paper with perforations, cut-outs and ragged 

edges.

• Do not use envelopes with windows or metal clasps.
• Do not use envelopes with self sealing flaps.
• Avoid using damaged or curled envelopes.

The manufacturer of this printer recommends the following 

guidelines when selecting transparencies and adhesive labels 

for use in your printer:

• Always use manual feed.
• Always use rear output.
• Media must be designed for use in laser printers or 

photocopiers and must be able to withstand 200°C 

(390°F) for 0.1 sec.
