    摘要： This invention relates to the method and apparatus for indicating roller wear in a media handling device. Such structures of this type, generally, employ the use of variable inductance to determine roller wear. The media transport roller has a non-conductive surface with a conductive core. Located just above the conductive core is a rod containing a power coil that is driven by AC excitation and a pick-up coil. The pick-up coil is connected to circuitry that measures the inductance. As the media transport roller wears, the conductive core moves closer to an inductive pick-up unit. The measured output voltage from the pick-up unit depends upon the distance between the core and the pick-up unit. This inductance change can then be correlated to media transport roller wear and relayed to the user through the use of an LED or other similar types of numerical/graphical displays.

    摘要： A system and method of detecting the presence of metallic objects in media to be conveyed in a medium transport system is disclosed. One or more metal detectors are included in the medium transport system to detect the presence of metal in the medium being transported. Signals from the metal detectors are sent to a system processor, which analyzes the signals, and produces proximity, duration, and/or intensity values therefrom. One or more microphones may also be included which detect the sound created as the medium is being transported. The processor computes sound values from the microphone signals, and analyzes the computed sound values along with the proximity, duration, and/or intensity values in order determine if the conveyance of the medium along the transport path should be stopped due to the presence of metal in the media or a jam occurring within the medium transport path.
