  • Cleaning device for a fixing unit
    Publication number: 20020122680
    Abstract: In a cleaning device for a fixing unit, a notched portion is formed in a winding shaft, which has an unused web wound therearound, at a position opposing a detecting position of a sensor. Accordingly, when a trailing end of the web comes to be exposed, and the web is disengaged from the wining shaft, the sensor measures the diameter of the notched portion, so that the diameter changes substantially. For this reason, an output of the sensor also changes substantially, and the trailing end of the web can be detected easily without being affected by the sensitivity of the sensor.
