Understanding paper and specialty media guidelines

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 on page 47.

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.
