摘要： A rapid warm-up and cool-down pressure roll assembly is provided and includes (a) a rotatable pressure roll including a cylindrical sleeve having an outer surface, and an inner surface defining a hollow interior to the rotatable pressure roll; (b) a thermoelectric assembly sheet positioned within the hollow interior and having a first substrate facing the inner surface of the cylindrical sleeve, a second substrate, an electric current flow path therethrough, and electric current input and output terminals associated with the electric current flow path; and (c) an electric current input switching device connected to the electric current input and output terminals for enabling selective reversing of a direction of electric current flow through the electric current flow path, thereby reversing which of the first substrate and the second substrate of the thermoelectric assembly sheet is hot and which is cold, and therefore selectively enabling a rapid warm-up or rapid cool-down of the cylindrical sleeve of the pressure roll.

摘要： There is disclosed an improved fuser cleaning system in which a strip of flexible material, including first second and third portions, is fed from a source roll to a take-up roll in such a manner that a fuser roll is cleaned or oiled. A first detectable mark may be disposed on a side of the strip of flexible material in one of the first and second portions. During operation of the fuser cleaning system, the third portion is taken up by the take-up roll and when an amount of the third portion is taken up by the take-up roll, the first detectable mark is detected by a sensor and a signal, indicating that the amount of the third portion has been taken up by the take-up roll, is transmitted to a controller. A second detectable mark may be disposed on the side of the strip of flexible material. When substantially all of the third portion has been taken up by the take-up roll, a signal is transmitted from the sensor to the controller indicating that substantially all of the third portion has been taken up by the take-up roll.

摘要翻译： 公开了一种改进的定影清洁系统，其中包括第一第二和第三部分的柔性材料条以这样的方式从源辊供给到卷取辊，使得定影辊被清洁或上油。 第一可检测标记可以设置在第一和第二部分之一中的柔性材料条的一侧上。 在定影器清洁系统的操作期间，第三部分被卷取辊吸收，并且当第三部分的量被卷取辊吸收时，第一可检测标记由传感器和信号 ，表示第三部分的量被卷取辊占据，被传送到控制器。 第二可检测标记可以设置在柔性材料带的侧面上。 当基本上所有第三部分已经被卷取辊吸收时，信号从传感器传送到控制器，指示基本上所有的第三部分已被卷取辊吸收。
