摘要:
In a reproduction machine having a fuser roller for fusing toner images on an image bearing sheet, a release agent management (RAM) system for applying an image offset prevent release agent to the fuser roller. The RAM system includes a rotatable supply core located to a first side of the fuser roller, a rotatable take up core located to a second side of the fuser roller, a release agent impregnated web member having a portion threaded between the supply core and the take-up core for contacting, and applying release agent to, the fuser roller, and a release agent supplying roll positioned for contacting and supplying release agent to the threaded portion of the web member. The release agent supplying roll has a non-continuous surface pattern that includes release agent supplying surface areas for contacting the threaded portion of the web member, and release agent non-supplying surface areas out of contact with the threaded portion of the web member.
摘要:
A roll fuser assembly including a fuser roll and a pressure roll. The rolls are crowned and are supported in pressure engagement with each other to form a fusing nip. The pressure engagement of the rolls eliminate nonuniform nip loading in wide fusers as well as providing uniform velocity through the fuser roll/pressure roll nip. It is preferred that the crowned profile of one of the rolls be substantially to the center of the roll and that the other be offset therefrom. It is further preferred that the diameters of each of the rolls be substantially the same at each end.

Embodiments herein comprise registrations module(s) positioned between image output terminal(s), feeder module(s), and/or finisher module(s). Each registration module comprises a casing having first mounting points that correspond to second mounting points on an adjacent module. The first mounting points and the second mounting points allow the registration module to be repeatedly connected to and disconnected from an adjacent module. Each registration module also includes sensors within the casing, a controller operatively connected to the sensors, and sheet feeders. The sensors determine alignment characteristics of media passing through the module and the controller is adapted to correct the alignment characteristics of the media through unequal rotation of the sheet feeders, if the alignment characteristics deviate from a predetermined standard.
