82 Clearing Jams
Back of the duplex unit
1 Push the button as shown. The duplex rear door opens.
2 Raise the duplex rear door. It remains in place.
3 Look under the rear door for the edge of the paper. Determine
how it is jammed:
– If a short piece is visible inside the duplex unit next to the
inner wall, grasp it and pull it out. If you cannot grasp it, see
“Inside the duplex unit” on page 81 for instructions.
– If only a short piece of paper is visible toward the rear of
the printer, do not pull it out; it may be easier to access
from inside the printer. See
“200 and 201 Paper Jam
Remove Cartridge” on page 72 for instructions to remove
the paper. However, if most of the paper is visible, continue
with the following.
