Abstract

An electrophotographic printing machine frequently employs O-rings as drive belts in the drive system. One problem which occurs during field service is the determination of the condition of the O-ring drive belts. Generally, these belts fail due to excessive stress relaxation. At present, the service person has no way of readily determining the condition of these belts. In order to provide a solution to this problem a series of concentric, different diameter, circular projections are molded on the interior surface of the printing machine cover. The diameter of each circular projection corresponds to the maximum allowable diameter of the O-ring drive belt, in the free state, before slipping occurs. The service person removes any questionable belt and attempts to slip it over the appropriate circular projection. If the belt fits over the circular projection, the belt has failed and should be replaced
