Replacing Broken or Missing Ribbons
Ribbons that break should be replaced
immediately. To avoid excessive stress on only
one new, slightly shorter ribbon, the entire set of
ribbons should be replaced. At a minimum, it is
recommended that ribbons be replaced in pairs.

Screwdriver: long shaft
Wrenches:
3/8”

one on each side of the machine.
5. While holding each adjustment bolt in
place, loosen its locknut (Figure 7-2, B).
6. Turn each bolt the same number of turns
counterclockwise until the ribbons are
easily moved by hand.

10. Reach under the feed table and pull the
end of the ribbon toward the front of the
unit. Make sure the ribbon end is below the
rod and between the feed ribbon guides.
Verify that the replacement ribbon follows
the path of the other ribbons.
11. Bring the ends of the ribbon together and
connect the ends with a new pin.
