							Clearing jams

6Clearing jams
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 on page 18. 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.
Identifying jams
When the printer jams, the appropriate jam message appears on the printer control panel.
Understanding jam messages
The following table lists the jam messages that can occur and the action necessary to clear the message. The jam 
message indicates the area where the jam occurred. However, it is best to clear the entire paper path to ensure you have 
cleared all possible jams.

image of a page may be reused after the page is printed but before it has successfully exited the 
printer if that memory is needed for another use. Therefore, a jammed page may or may not be 
reprinted, depending on the overall memory usage in the printer.
