Return Ribbon Tension Spring
Replacement
Tension on the return ribbons is held by the
weight of the return ribbon guide assembly. There
is no adjustment.
There is a spring (Figure 7-33, A) attached
to the return guide assembly bearing in each
endframe which prevents the assembly from
bouncing too much. These springs may wear and
need periodic replacement.
