Understanding paper and specialty media guidelines
Avoiding jams
Use appropriate print media (paper, transparencies, labels, and card stock) to help ensure trouble-free printing. See
Supported print media for more information.
Note: Try a limited sample of any print media you are considering using with the printer 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 trays, Loading the multipurpose feeder, or Loading the 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.
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 Clearing jams for more information.
Note: If you have a recurring paper jam, see Paper frequently jams. for more information.
