摘要： A heat and pressure fuser includes a thin web which is wrapped around a portion of a heated fuser roll to form a fusing area. The web contacts the fuser over a relatively short wrap angle to reduce torque required to drive the fuser roll, thereby enabling a higher process speed. Fusing efficiency is maintained by use of a biasing mechanism which increases the pressure applied to the web both the entrance and exit areas of the fuser.

摘要： To disengage the cleaning blade from the photoreceptor of a reproduction machine and avoid cold set and damage to the photoreceptor during prolonged machine shutdowns, a bi-metal coil spring is positioned inside the fusing roll to sense fuser temperatures, with linkage coupling the spring to the cleaning blade so that when fuser temperatures fall below a preset operating temperature, the spring relaxes permitting a weighted member to retract and disengage the blade from the photoreceptor.

摘要： A low mass fuser roll fusing system incorporates a thin web member to maintain copy sheets in biased contact with a fuser roll during a fusing operation. The copy sheets are introduced to the fusing area at an entrance nip formed by a biasing assembly. The lead edge of the copy sheet is introduced into the entrance nip by a reciprocating mecahnism which moves, the web member and the copy sheet supported thereon into the entrance nip. The web member motion is then stopped and the copy sheet progresses through the fusing cycle until the copy sheet emerges from the fusing area, at which time the web member is returned to its original position.

摘要： A document transport system for transporting and selectively recirculating relatively large documents through a processing station. In accordance with this invention, a transport is provided which has a defined endless document path. A gripper bar is provided for selectively and releasably securing the leading edge of large documents, and a driven chain is also provided for supporting and moving the gripper bar at a predetermined imaging speed through an imaging station. Further, drive rollers are provided proximate the imaging station to urge documents in the document path through the imaging station at the predetermined imaging speed. The invention also includes control apparatus for halting the gripper bar at a first position downstream from the processing station to enable release of documents from the gripper bar and at a second position upstream from the processing station to enable selective insertion and retention of documents in the gripper bar. Finally, the chain also recirculates the gripper bar from the first position to the second position at a rate substantially faster than the imaging speed to enable rapid recirculation of documents for imaging and rapid insertion of a new document for imaging after release of a previously imaged document.
