1. Check the bolts securing the mechanism base to the base
pan. Tighten the mechanism base mounting bolts if they
are loose enough to permit movement of the mechanism
base.
2. Remove the shuttle cover. Check the shuttle frame
assembly mounting/clamp screws for looseness. Torque
the 5/32 inch socket head clamp screws to 30 inch-pounds
(3.39 N•m). Torque the center captive 5/32 inch socket
head screw to 30 inch-pounds (3.39 N•m).
3. Inspect the shuttle area for loose hardware. Tighten loose
hardware.
4. Check that the hammer bank cover assembly is correctly
installed, that it has not slipped off the mounting pegs.
Check that the ribbon mask has not partially separated
from the hammer bank cover. Check for debris trapped
between the ribbon mask, hammer bank cover, and
hammer bank. Clean the shuttle frame assembly and
hammer bank cover assembly if you find debris. Replace
the hammer bank cover assembly if you find any damage
to the ribbon mask or hammer bank cover.
5. Power on the printer. Run a shuttle test. Replace the
shuttle frame assembly if it is noisy or rattles.
