ABSTRACT:
A stabilizing device containing two bonded elastomeric materials with restitution coefficients that vary inversely with temperature changes. The resultant restitution coefficient of the printer hammer back-stopper remains relatively constant regardless of temperature variations in the back stopper caused by heat generated by the operation of a hammer solenoid.
