The bias charge that pulls the image from the drum onto the belt is applied by the transfer roller to the underside of the ITB.
- A negative bias is applied to the roller opposing the paper transfer roller to separate the paper from the belt (repulsive separation) in the PTR unit farther downstream.
- The bias at both points is supplied from the same power pack, the transfer power pack.
- By monitoring the resistance of the roller opposing the PTR, the machine determines the amount of wear in the roller and uses this mearurement to trigger SC453. When this occurs, a message is displayed on the operation panel to alert the user that the opposing transfer roller will need replacement soon and that they should call for service.
