Clearing Paper Jams
Open the upper right cover of the main unit.
If the optional Paper Deck-V1 is attached to the main unit, move the paper deck
away from the main unit before proceeding with this procedure. For more
information, see "Paper Deck-V1," on p. 3-9.
Remove all of the paper that is not jammed from the stack
bypass.
