3. Unlatch both ribbon spools and carefully lift them off the hubs. Raise the
ribbon out of the ribbon path.
4. Using a soft-bristled, non-metallic brush (such as a toothbrush), brush
paper dust and ribbon lint off the tractors, shuttle cover assembly, base
casting, and ribbon guides. Vacuum up the residue.
5. Wipe the splined shaft with a soft cloth.
6. Check the ribbon mask and hammer bank cover for bits of torn paper or
ribbon lint. Check the holes in the ribbon mask surrounding each hammer
tip. Gently remove paper or lint particles with a wooden stick or pair of
tweezers. (Do not pry or apply force to the hammer tips.)
7. Using a soft cloth lightly moistened with anhydrous alcohol (no water),
remove dust and ink from the platen. (The platen is the thick silver bar
behind the hammer bank cover that rotates when the forms thickness
lever is rotated.) Clean the ribbon guides.
8. Brush and vacuum up dust or residue that has accumulated inside the
lower cabinet.
9. For cabinet models:
Wipe the lower cabinet interior with a clean, lint-free cloth dampened (not
wet) with water and mild detergent, or spray the surfaces lightly with
window cleaning solution. Dry the lower cabinet interior by wiping it with a
clean, lint-free cloth.
10. For models with a power paper stacker:
Wipe all power stacker components using a soft cloth lightly moistened
with anhydrous alcohol (no water) to remove dust.

Quick Reference Guide.
Caution Vacuum carefully around the hammer bank and surrounding area to
avoid damage.
Caution When cleaning the platen, be very careful not to get any alcohol in the
hammer bank, because alcohol will cause severe damage to the
hammer bank. Only a trained service technician should clean the
shuttle assembly.
