By carefully selecting print media and loading it properly, you should be able to avoid most paper jams. For more 
information on avoiding paper jams, see Avoiding jams. If jams do occur, follow the steps outlined in this section.

To resolve the paper jam messages, you must clear the entire paper path and then press 

 to clear the message and 

resume printing. The printer prints a new copy of the page that jammed if Jam Recovery is set to On or Auto; however, the 
Auto setting does not guarantee the page will print.

If the printer jams, the appropriate jam message will be displayed on the printer operator panel. If you select Show areas 
on the operator panel, you can view one or more images to help you clear the jam.

See the diagram on page 81 for an overview of the paper path and areas where jams may occur. The path varies 
depending on the paper source and output bins.
