ABSTRACT:
A fuser for an electrophotographic printer or copier has a fuser roll and pressure roll that form a nip through which a recording paper having a toner image is passed to fuse the toner image thereon. The fuser includes a cleaning web system to clean the fuser roll having a web supply roll, a tension roll to press the web against the fuser roll, and a web take up roll. To prevent spooling of the web from the supply roll during a paper jam clearance while the pressure roll is in contact with the fuser roll, a torsion spring is mounted on the tension roll shaft. The torsion spring provides enough torsional force on the tension roll to prevent rotation thereof during a jam clearance, thus preventing web spooling. During normal operation, the take up roll intermittently overcomes the torsion spring to step the web thereon.
