363 Troubleshooting Avoiding Jams• Use only recommended print media.• See "Loading Print Media in the Multipurpose Feeder (MPF)" on page 150 and "Loading PrintMedia in the Priority Sheet Inserter (PSI)" on page 158 to load print media properly.• Do not overload the print media sources. Ensure that the stacked print media does not exceedthe 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, tryfeeding 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.• Ensure that the recommended print side is face up when you insert the print media.• Keep print media stored in an acceptable environment.• Do not remove the paper cover during a print job.• Ensure that all cables that connect to the printer are correctly attached.• Overtightening the guides may cause jams.See also:• "About Print Media" on page 138• "Supported Print Media" on page 143• "Print Media Storage Guidelines" on page 142
