A tensioning and detensioning assembly includes a frame and a moveable tensioning roll for tensioning the continuous loop belt. The moveable tensioning roll has an axis, a first end, a second end, a first position for tensioning the continuous loop belt, and a second position when the continuous loop belt is detensioned. When the moveable tensioning roll is in the second position, the first end is spaced a first distance from the first position, and the second end is spaced (from the first position) a second distance that is different from the first distance in order to enable safe, efficient and controlled, non-slipping removal and reinstallation of the flexible closed loop photoreceptor belt. The tensioning and detensioning assembly also includes a first moving means for moving the moveable tensioning roll into the first position, and a second moving means for moving the first end through the first distance, and the second end through the second distance, thus moving the moveable tensioning roll into the second position, and thereby enabling controlled and non-slipping removal and reinstallation of the belt or photoreceptor.
