outside, place the right spool
on the full hub. Press down
on the spool until the hub
latch snaps in place.
Install the ribbon around the
ribbon guide and along the
ribbon path. (Refer to the
ribbon path diagram on the
shuttle cover.) Be sure to
thread the ribbon between
the hammer bank cover and
the ribbon mask.

twisted ribbon can lower print quality,
shorten ribbon life, or cause paper jams.
