Storing media
Use the follo wing guidelines for proper media st orage. These help av oid media feeding prob lems and uneven print
quality:
• For best results, store media in an environment whe re the t e mpe rature is approximately 21°C (70°F) and
the relative humidity is 40%.
• Store cartons of media on a pallet or shelf, rather than directly on the floor.
• When storing individual package s of media out of the original carton, make sure the y rest on a flat surf ace
so the edges do not buckle or curl.
• Do not place anything on top of the media packages.
• Store paper in its original wrapper until you load it into the printer.
Avoiding jams hints
The followi ng hints can help avoid jams:
• Use only recommended paper or specialty media (referred to as media).
• Do not overload the media sources. Make sure the stack height does not exceed the maximum height
indicated by the load line labels in the sources.
• Do not load wrinkled, creased, damp, or curled media.
• Flex, fan, and straighten media before you load it. If jams do occur with print media, try feeding one sheet
at a time through the multipurpose feeder.
• Do not use media that has been cut or trimmed by hand.
• Do not mix media sizes, w eights, or types in the same media source.
• Make sure the recommen ded print sid e is loaded in the s ourc e accord ing to y our s implex or duple x needs .
• Keep media stored in an acceptable environment . See “Storing media” for more information.
• Do not remove tr ays during a print job.
• Push all trays in firmly after loading them.
• Make sure th e guides in the tra ys are properly posit ioned for the s ize of media loaded. Make sure the guides
are not placed too tightly against the st ack of media.
• Make sure all cabl es that connect to the printer are correctly attached. See the Setup sheet for more
information.
• If a jam occurs, clear the entire media path. Se e the User’s Guide for information on clearing jams.
