and size of paper on page 2.)

paper.If there is paper in the paper tray, make sure it is straight. If the paper is curled, 
straighten it before printing. Sometimes it is helpful to remove the paper. Turn the 
stack over and put it back in the paper tray. If the paper continues to curl, replace 
the paper.

the page setup or document setup menu of your software. (See your application 
manual.)

Paper jams and how to clear them6
If paper jams inside the machine, the machine will stop. One of the following LCD messages will appear to 
tell you where to find the jammed paper.
 
JamMPTray (1)
Paper jam in the MP tray. (See page 147.)
JamTray1 (2)
Paper jam in the standard paper tray (Tray 1). (See page 147.)
JamTray2 (3)
Paper jam in the lower tray (Tray 2). (See page 147.)
Jam Duplex (4)
Paper jam underneath the standard paper tray (Tray 1) or in the fuser unit. (See page 150.)
Jam Rear (5)
Paper jam where the paper comes out of the machine. (See page 153.)
Jam Inside (6)
Paper jam inside the machine. (See page 156.)
If the error message still appears on the LCD after you remove the jammed paper, there may be more paper 
jammed somewhere else. Check the machine thoroughly.
Note
Always remove all paper from the paper tray and straighten the stack when you add new paper. This helps 
prevent multiple sheets of paper from feeding through the machine at one time and prevents paper jams.
