    • A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. Two heating elements heat the fuser roll. One of the heating elements is configured for heating a first portion of the fuser roll while a second of the heating elements is configured for heating a second portion of the fuser roll. The second portion of the fuser roll is axially spaced from the first portion. A temperature sensing system monitors a temperature of the fuser roll in a first location and monitors a temperature of the fuser roll in a second location which is axially spaced from the first location. A control system determines an amount of power to supply to the first heating element as a function of the monitored temperatures at the first and second axially spaced locations and determines an amount of power to supply to the second heating element as a function of the monitored temperatures at the first and second axially spaced locations.
    • 定影装置包括定影辊和在其间限定辊隙的压力辊。 两个加热元件加热定影辊。 加热元件中的一个被配置用于加热定影辊的第一部分,而第二加热元件被配置用于加热定影辊的第二部分。 定影辊的第二部分与第一部分轴向间隔开。 温度感测系统在第一位置监测定影辊的温度,并且在与第一位置轴向间隔开的第二位置中监测定影辊的温度。 控制系统根据第一和第二轴向间隔位置处监测到的温度确定供应给第一加热元件的功率量,并确定供应给第二加热元件的功率的量作为监测温度的函数 在第一和第二轴向间隔的位置。

    • A fuser system includes first and second nip rolls, rotably mounted parallel to and in contact with each other to form a nip through which print media with a toner image thereon is passed to fuse the image to the print media. A cleaning web system is provided for cleaning one of the nip rolls of unfused toner. The cleaning web system includes first and second rotatable web rolls. A web extends between the first and second web rolls and contacts the first nip roll. A drive system is operatively coupled with one or both of the first and second web rolls for advancing the web in a first direction and thereafter in a second direction opposite the first direction.
    • 定影器系统包括第一和第二夹持辊,可旋转地安装成彼此平行并且彼此接触以形成辊隙,通过该辊隙通过其上具有调色剂图像的打印介质将图像熔合到打印介质。 提供清洁网系统用于清洁未熔合的调色剂的夹辊之一。 清洁网系统包括第一和第二可旋转卷筒纸卷。 纸幅在第一和第二卷筒纸之间延伸并且接触第一压合辊。 驱动系统可操作地与第一和第二卷筒纸辊中的一个或两个操作地联接,用于沿第一方向推进卷筒纸,然后在与第一方向相反的第二方向上推进卷筒纸。
