Checking for and clearing paper jams
Paper jams can occur in three areas in the printer:
m where paper goes into the printer (pickup area and paper cassette)
m where printing happens (transfer drum)
m where paper comes out of the printer (fuser and output trays)
IMPORTANT If you experience paper jams after you first set up the printer,
check all areas of the printer to make sure that the cardboard and orange
plastic packing materials have been removed.
