Typical belt photoreceptor drive systems (i.e. Xerox machines 1065, 1075, 1090, 5090F and new mid-volume machines) rely on the frictional characteristics between the back of the photoreceptor belt and the drive roll to provide a sufficient drive force to overcome the drag generated by xerographic process elements. For future mid-volume products, the combination of acoustic transfer assist (ATA) vacuum and the photoreceptor cleaner are expected to create about 4 to 6 pounds of drag. While the drive capability when the system is clean and new is sufficient (photoreceptor to roll coefficient of friction 1 to 2, which provides 7 to 10 pounds drive force) to overcome these drags, when the drive roll and photoreceptor back become contaminated, the drive capability drops (coefficient of friction 0.2 through 0.4, which provides two to three pounds drive force) below the required level and belt slip on the drive roll will occur.
