摘要： An electrostatographic reproduction machine including a contact belt fusing apparatus for fusing copy sheets without belt skew defects. The fusing apparatus includes an endless fusing belt having an external fusing surface defining a path of movement and a plurality of support rollers for supporting and moving the endless fusing belt along the path of movement. The endless fusing belt as supported has a preferred fusing position properly aligned on the plurality of support rollers. The fusing apparatus includes a pressure roller forming a fusing nip with the external fusing surface of the endless fusing belt for contacting and moving toner image carrying sheets therethrough. Importantly, the fusing apparatus also includes a dual function belt deskewing and heating assembly for heating the external fusing surface of the endless fusing belt and deskewing the fusing belt from a sensed skewed position to the preferred fusing position. The dual function belt deskewing and heating assembly includes a heated roller for contacting and heating the fusing belt, and skewing means for skewing the heated roller to controllably move the endless fusing belt in a deskewing manner from a sensed skewed position to the preferred fusing position, thereby preventing belt skew defects on fused copies.

摘要： A contact belt fusing apparatus is provided for reducing sheet edge wear defects in fused copies. The fusing apparatus includes an endless fusing belt having an external fusing surface defining a path of movement and a plurality of support rollers for supporting and moving the endless fusing belt along the path of movement. The endless fusing belt as supported has a first fusing position aligned on the plurality of support rollers at a first location, and at least a second fusing position aligned on the plurality of support rollers at a second location that is spaced axially from the first location thereon. The fusing apparatus also includes heating member for heating the external fusing surface of the endless fusing belt, and a pressure roller forming a fusing nip with the external fusing surface of the endless fusing belt for contacting and moving toner image carrying sheets therethrough, the toner image carrying sheets having edges that induce wear on the external fusing surface of the endless fusing belt. Importantly, the fusing apparatus includes a belt moving mechanism for controllably moving the endless fusing belt axially, relative to the plurality of rollers, from the first fusing position to the at least second fusing position, so as to reduce sheet edge wear on the external fusing surface of the endless fusing belt.
摘要翻译：提供一种接触带定影装置，用于减少熔融复印件中的边缘磨损缺陷。定影装置包括具有限定运动路径的外部定影表面的环形定影带和用于支撑和移动环形定影带沿运动路径的多个支撑辊。支撑的环形定影带具有在第一位置处对准在多个支撑辊上的第一定影位置，以及在与其上的第一位置轴向间隔开的第二位置处的多个支撑辊上的至少第二定影位置。定影装置还包括用于加热环形定影带的外部定影表面的加热构件和与环形定影带的外部定影表面形成定影辊隙的压力辊，用于接触和移动调色剂图像承载片材，调色剂图像携带具有在环形定影带的外部熔融表面上引起磨损的边缘的片材。重要的是，定影装置包括一个带移动机构，用于相对于多个辊轴向地可控地移动环形定影带，从第一定影位置到至少第二定影位置，以便减少外部熔断时的边缘磨损环形定影带的表面。

摘要： A heat and pressure belt fuser structure having an endless belt and a pair of pressure engageable members between which the endless belt is sandwiched for forming a fusing nip through which substrates carrying toner images pass with the toner images contacting an outer surface of the endless belt, at least one of the pressure engageable members has a deformable layer, and the endless belt has a thickness of from about 1 to about 8 mm; and the fuser structure includes an external source of thermal energy for elevating a pre-nip area of the belt. The thick belt in combination with a deformable layer of at least one of the pressure member(s) cooperate to provide a large nip and adequate creep for intrinsic paper stripping.
