Abstract
The present application is directed to toner transfer systems with an adjustable transfer belt. The transfer belt transfers toner images from a first location to a second location. Two or more support rolls position and drive the transfer belt. A tensioning device is operatively connected to one of the support rolls. The tensioning device moves the support roll between a first position that places a first amount of tension on the belt, and a second position that places a lesser second amount of tension on the belt. The support roll is in the first position during image formation, and in the second position during non-image formation such as storage and shipping.
