SECTION VI.
TYPE 122 PRINTER
aluminum foil at the beginning of the printer ribbon is sensed.
At this point, the ribbon is completely rewound onto the
disposable upper ribbon supply mandrel, the RIBBON indi-
cator on the printer main control panel is illuminated, and the
program is stopped.
b.
Depress the TYPE ROLL OFF button.
c.
Pull the ribbon cover back.
d.
The ribbon leader is secured to the take-up (lower) mandrel
by a strip of two-sided adhesive tape.
Remove the leader
from the take-up mandrel by peeling the adhesive away from
the mandr el.
e.
Manually wind the remaining leader back through the ribbon
feed path onto the supply mandrel.
Remove the supply mandrel
from the printer by pressing it to the right.
The right pulley
of the mandrel is spring-loaded, thus allowing it to be moved
to the right to disengage the mandrel from the keyed left pulley.
Dispose of the used ribbon and supply mandrel.
f.
Mount the new disposable mandrel and ribbon on the upper shaft
so that the new ribbon will feed from the top side of the roll.
Be
sure that the new mandrel is keyed properly in the left pulley
and that it is mounted securely on the right pulley.
g.
Open the type roll housing completely by releasing the toggle
clamp bar and pulling the type roll housing upward away from
the print hammer base.
h.
Unwind a portion of the new ribbon leader and thread it between
the two paper standoff bars, making sure that the aluminum foil
side of the ribbon is on the outside of the roll as it is unwound.
Pull the leader through the ribbon feed path until there is sufficient
slack to enable it to be attached to the lower take-up mandrel.
i.
Peel the protective covering off the two-sided adhesive tape on
the ribbon leader and line up the edge of the adhesive with the
scribed guide line on the take-up mandrel.
This action ensures
that the ribbon is aligned properly, thus helping to prevent
ribbon skew during printing operations.
Secure the leader to
the take-up mandrel by applying pressure to the adhesive tape.
Manually wind the take -up mandrel until the ribbon leader is
completely wound onto the mandrel.
j.
Engage the type roll housing by swinging it downward into place
and relatching the toggle clamp bar.
k.
Start the type roll by depressing the TYPE ROLL ON button.
