Storing Print Media; Avoiding Jams - Lexmark X644e User Manual

• 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 is 40%.
• Store cartons of paper on a pallet or shelf rather than directly on the floor.
• If you store individual packages of paper 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 paper packages.
• Store paper in its original wrapper until you load it into the MFP.

Avoiding jams

Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-
free printing. See Supported print media
Note: Try a limited sample of any print media you are considering using with the MFP
before purchasing large quantities.
By selecting the appropriate print media and loading it properly, you can avoid most jams. See
Loading standard trays and optional
2000-sheet drawer for detailed tray-loading instructions.
The following hints can help you avoid jams:
• Use only recommended print media.
• Do not overload the print media sources. Make sure the stack height does not exceed the
maximum height indicated by the stack line on the labels in the sources.
• Do not load wrinkled, creased, damp, or curled print media.
• Flex, fan, and straighten print 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 print media that you have cut or trimmed yourself.
• Do not mix print media sizes, weights, or types in the same print media source.
• Make sure the recommended print side is loaded in the source according to your simplex or
duplex needs.
