To avoid damage, always remove misfed media gently, without tearing it. Try to remove the paper in the 
direction that the paper would normally feed. Any piece of media left in the printer, whether large or 
small, can obstruct the media path and cause further misfeeds. Do not reload media that has misfed.
Note:The printed side of jammed pages may smudge, and the toner may stick to your hands. Do 
not touch the printed side of the media when removing it. Make sure not to spill any toner inside 
the printer.
WARNING:If you accidentally get toner on your clothes, lightly dust them off as best as you can. 
If some toner remains on your clothes, use cool, not hot water, to rinse the toner off. If toner gets 
on your skin, wash it off with cool water and a mild soap. If you get toner in your eyes, wash it out 
immediately with cool water and consult a doctor.
Clearing Paper Jams from Tray 1, Tray 2, Tray 3 or Tray 4
