    • A fuser for fusing toner images to a receiving sheet includes a pressure roller and a fusing belt. The fusing belt has leading and trailing ends. A towing device is positioned to receive both the leading and trailing ends of the belt to form an endless belt. The towing device is moved through a path which moves the fusing belt through an endless path, which path includes a fusing nip with the pressure roller. The belt is backed by a heated roller at the fusing nip which defines a portion of the endless path and cooperates with the pressure roller to provide pressure in the nip.
    • 将调色剂图像定影到接收片的定影器包括压力辊和定影带。 定影带有前端和尾端。 牵引装置定位成接收带的前端和后端以形成环形带。 牵引装置移动通过使定影带通过环形路径移动的路径,该路径包括与压力辊的定影辊隙。 皮带在定影辊隙处由加热的辊支撑,该定影辊隙限定环形路径的一部分,并与加压辊配合以在辊隙中提供压力。

    • Multicolor toner images are formed on a receiving sheet by superimposing single toner color images formed electrostatically on an image member, in registration on the receiving sheet. The receiving sheet is carried by a transfer roller repeatedly through engagement with the image member. The transfer roller is held slightly out of engagement with the image member when no receiving sheet is between the roller and image member. When a receiving sheet is between the roller and image member the roller is driven through the receiving sheet by the image member. To improve registration, the transfer roller is reindexed between transfer of each image by a stepper motor which rotates the transfer roller when no sheet is present between the transfer roller and the image member.
    • 多色调色剂图像通过将形成在静电上的单个调色剂彩色图像重叠在接收片上而形成在接收片上。 接收片材​​通过与图像构件的接合重复地由转印辊承载。 当辊和图像构件之间没有接收片材时,转印辊略微与图像构件接合。 当接收片材位于辊和图像构件之间时,辊被图像构件驱动通过接收片材。 为了改善配准,当在转印辊和图像构件之间没有纸张时,通过使转印辊旋转的步进电动机在转印每个图像之间转印辊。
