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.

Although there are several places a jam can occur, clearing the paper path is fairly easy depending on the jam message or 
messages displayed on the operator panel.

Paper jams can occur in three areas: the front of the printer, inside the printer, and at the rear of the printer. Jams in the 
front of the printer occur in the input options or the duplex tray. Jams inside the printer occur in two locations and require the 
removal of the print cartridge. Jams can also occur at the rear of the printer or in one of the output options.

Note: The following clearing jam instructions may seem out of numerical sequence. However, they have 

been grouped to help you quickly clear the print path. To go to a specific jam, see Understanding 
jam messages.
