Troubleshooting 349
îš„ Avoiding Jams
• Use only recommended print media. See "About Print Media" on page 114 for more information.
• See "Loading Print Media in the Multipurpose Feeder (MPF)" on page 123
and "Loading Print
Media in the Priority Sheet Inserter (PSI)" on page 131 to load print media properly.
• Do not overload the print media sources. Make sure that the stacked print media does not
exceed the maximum height indicated on the paper width guides.
• Do not load wrinkled, creased, damp, or curled print media.
• Flex, fan, and straighten print media before you load it. If a jam occurs with print media, try
feeding one sheet at a time through the MPF or the PSI.
• Do not use print media that you have cut or trimmed.
• Do not mix print media sizes, weights, or types in the same print media source.
• Make sure that the recommended print side is facing up when you insert the print media.
• Keep print media stored in an acceptable environment. See "Print Media Storage Guidelines" on
page 118 for more information.
• Do not remove the PSI during a print job.
• Make sure that all cables that connect to the printer are correctly attached.
• Overtightening the guides may cause jams.
