Storing Media; Avoiding Jams Hints - Lexmark T640 Connection Manual

Storing media

Use the following guidelines for proper media storage. These help avoid media feeding problems and uneven print
quality:
• For best results, store media in an environment where the temperature 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 packages of media out of the original carton, make sure they rest on a flat surface
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 following 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, weights, or types in the same media source.
• Make sure the recommended print side is loaded in the source according to your simplex or duplex needs.
• Keep media stored in an acceptable environment. See "Storing media" for more information.
• 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 media loaded. Make sure the guides
are not placed too tightly against the stack of media.
• Make sure all cables that connect to the printer are correctly attached. See the Setup sheet for more
information.
• If a jam occurs, clear the entire media path. See the User's Guide for information on clearing jams.
