A fuser and receiver release system and method are provided for improving the release of receivers in high speed of printing systems. This system controls the release of a receiver in conjunction with a fuser in a printing system, and specifically the efficiency and accuracy of the release system. One embodiment of this method includes a belt fuser that allows the separating of the heat transfer and release functions of the fuser such that fuser roller could be made of hard metal core that can be heated to high temperatures without the fear of delaminating elastomeric coatings which are common in roller fusing.

A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. The web-cleaner has two wiper blades, including one or more profiled metal blades, each having a distinguishment such that the distinguishment distinguishes one wiper blade from the other wiper blade when the blades are locked into the cleaner sump by springs, to facilitate material removed from the web. The wiper cleaning blades and the cover assembly are easily replaceable by the operator in the correct order.

A variable torque device for maintaining constant tension in a web of material as the web is unwound from a supply roll. The variable torque device includes a lead screw attached to the shaft of the supply roll via an appropriate gear ratio. A coil spring is located between a hub on the lead screw and a set of rings and friction pads. As the lead screw rotates, the hub translates, thus changing the displacement of the coil spring, which in turn changes the loading of the rings and friction pads. With a full supply roll the coil spring is compressed so as to create an amount of torque to create the desired web tension. As the supply roll unwinds, the rotation of the lead screw translates the hub to expand the coil spring, reducing the torque and maintaining the web tension constant.

A precision release agent management system for an electrostatographic reproduction apparatus fuser device. The precision release agent management system includes a reservoir adapted to contain a release agent. A wick absorbs release agent from the reservoir. A metering member receives release agent from the wick, which is supported for resiliently urging into operative contact with the metering member. A blade member is associated with the metering member to establish a desired thickness of release agent on the metering member, and a donor member is adapted to receive release agent from the metering member, and operatively contact the fuser device to apply the release agent thereto. A plurality of features is associated with the reservoir for precise alignment of the donor member, the metering member, and the metering blade.
