Abstract

In an electrophotographic printing machine, the photoconductive belt may have a limited life. Thus, the belt must be periodically replaced during the life of the printing machine. Heretofore, in order to replace the photoconductive belt, the entire belt module had to be removed from the printing machine. When the belt module was removed from the printing machine, slack was introduced between the rollers to permit the ready removal of the photoconductive belt therefrom and the replacement thereof with a new photoconductive belt. Alternatively, it is feasible to employ the lateral movement of the belt to replace a used photoconductive belt with an unused one. More particularly, the steering roller is tilted such that the old photoconductive belt moves laterally off the belt support rollers. Thereafter, the steering roller is once again tilted in the opposite direction, so that the new photoconductive belt moves laterally onto the support rollers. The steering roller is then adjusted to maintain movement of the photoconductive belt along a predetermined path.
