    • A fault diagnosis section activates a driving component alone, measures an operation state signal and a paper passage time, and stores feature values (Vm, ov, Tqs, ots) extracted as a determination reference in a storage medium. A paper passage fault determination section determines whether or not a fault has arisen on the basis of the paper passage time when an apparatus is under normal operating conditions. A diagnosis target block determination section determines an order to operate a detail fault diagnosis when it is determined that there is a plurality of diagnosis target blocks. When the driving component is activated alone under actual operation conditions, the operation state signal Vf is obtained, and an operation state fault determination section conducts diagnosis on whether or not a fault has arisen on the driving component and a state of the fault, and whether or not a fault has arisen on other power transmission components and a nature of fault with reference to the feature values as the determination reference on the basis of a degree of deviation from a normal range.
    • 故障诊断部分单独激活驱动部件,测量操作状态信号和纸张通过时间,并将作为确定基准提取的特征值(Vm,ov,Tqs,ots)存储在存储介质中。 纸通过故障判定部根据设备处于正常工作条件下的纸张通过时间来判定故障是否发生。 当确定存在多个诊断目标块时,诊断目标块确定部分确定操作细节故障诊断的顺序。 当在实际操作条件下单独激活驱动部件时,获得操作状态信号Vf,并且操作状态故障确定部分是否对驱动部件发生故障和故障状态进行诊断,以及是否 或者不是基于与正常范围的偏离程度参照作为确定参考的特征值而在其它动力传递部件和故障的性质上产生故障。

    • A fault diagnosis section activates a driving compornent alone, measures an operation state signal and a paper passage time, and stores feature values (Vm, σv, Tqs, σts) extracted as a determination reference in a storage medium. A paper passage fault determination section determines whether or not a fault has arisen on the basis of the paper passage time when an apparatus is under normal operating conditions. A diagnosis target block determination section determines an order to operate a detail fault diagnosis when it is determined that there is a plurality of diagnosis target blocks.
