DRIVE MECHANISM FOR AN INTERMEDIATE TRANSFER MEMBER MODULE OF AN ELECTROPHOTOGRAHIC IMAGING DEVICE

An intermediate transfer member (ITM) module including a frame; a backup roll and a drive roll rotatably disposed along a first end portion of the frame. A tension roll is rotatably disposed along a second end portion of the frame. An ITM belt forms an endless loop around the backup roll, the drive roll and the tension roll such that rotation of the drive roll causes the ITM belt to translate and the tension roll and the backup roll to rotate. The drive roll and the backup roll form a transfer nip with a transfer roll. A drive mechanism is coupled between the drive roll and the backup roll and includes a plurality of gears. The drive mechanism overdrives the backup roll relative to the drive roll while limiting an amount of tension of the ITM belt in the second transfer nip.
