Abstract
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.
