Selecting print media
Selecting the appropriate print media for the MFP helps you avoid printing problems. The following 
sections contain guidelines for choosing the correct print media for the MFP.
Paper
For the best print quality, use 75 g/m2 (20 lb) xerographic, grain long paper. Try a sample of any 
paper you are considering using with the MFP before buying large quantities,.
When loading paper, note the recommended print side on the paper package, and load paper 
accordingly. See Loading...

supported chemically treated papers)

Transparencies
The MFP can print directly on transparencies designed for use in laser printers. Print quality and 
durability depend on the transparency used. Always print samples on the transparencies you are 
considering before buying large quantities. 
The Paper Type setting should be set to Transparency to help prevent jams. In Macintosh, be sure to 
set the Paper Type to Transparency in the Print dialog on the Imaging choice in the Copies & Pages 
pop-up menu.

Use envelopes that can withstand temperatures of 230°C (446°F) without sealing, excessive 
curling, wrinkling, or releasing hazardous emissions. If you have any doubts about the 
envelopes you are considering using, check with the envelope supplier.

Do not load labels with paper or transparencies in the same source; mixing print media can 
cause feeding problems and print quality problems.
Do not use label sheets with a slick backing material.
Use full label sheets. Partial sheets may cause labels to peel off during printing, resulting in a 
jam. Partial sheets also contaminate the MFP and your cartridge with adhesive, and could 
void the MFP and cartridge warranties.
Use labels that can withstand temperatures of 230°C (446°F) without...

Avoid using card stock that may release hazardous emissions when heated.
Do not use preprinted card stock manufactured with chemicals that may contaminate the 
MFP. Preprinting introduces semi-liquid and volatile components into the MFP.
We recommend the use of grain short card stock.
Storing print media
Use the following guidelines to avoid paper feeding problems and uneven print quality.
Store paper in an environment where the temperature is approximately 21°C (70°F) and the 
relative humidity...

Keep print media stored in an acceptable environment. See Storing print media.
Do not remove trays during a print job.
Push all trays in firmly after loading them.
Make sure the guides in the trays are properly positioned for the size of print media you have 
loaded. Make sure the guides are not placed too tightly against the stack of print media.
If a jam occurs, clear the entire media path. See  for more information.
Note:If you have a recurring paper jam, see Paper frequently jams.
