Precautions for clearing jammed paper
Be sure to observe the following points when you clear jammed 
paper.
❏ Do not remove jammed paper by force. Torn paper can be 
difficult to remove and might cause other paper jams. Pull it 
gently in order to avoid tearing.
❏ Always try to remove jammed paper with both hands to avoid 
tearing it.
❏ If jammed paper is torn and remains in the printer, or if paper 
is jammed in a place not mentioned in this chapter, contact 
your dealer.
❏ Make sure that the paper type that is loaded is the same as the 
Paper Type setting in the printer driver.
