摘要： A sheet path velocity profile signature analysis apparatus which utilizes output from various idler rolls (82) throughout the machine paper path to detect abnormalities. The idler rolls (82) are in frictional contact with device rolls (84) defining therewith a nip through which individual sheets pass. The idler rolls (82) are coupled to an encoder (86) for generating a signal as a function of the rotational speed of the idler rolls (82). The constantly monitored and instantaneous velocity readings are compared with a base line velocity signature established at the factory. If the constantly monitored velocity profile is not within the pre-established operating parameters as set at the factory, automatic machine adjustment procedures are initiated and/or automatic service alerts are issued. The ability to constantly monitor the velocity profile throughout the machine enables preventative maintenance to occur and worn drive rolls, idler rolls and other transport devices can be replaced before catastrophic failure.

摘要： A copy machine includes a photoreceptor (10) for storing a document image, a transfer station (D) for transferring a stored document image to a sheet of copy paper at a transfer location, a supply tray (33) for storing a quantity of copy sheets (31), transport rollers (17, 19) for conveying copy sheets along a path from the supply tray to the transfer location, a detector (40) for detecting a misfeed in the path and for outputting a misfeed signal, and a controller (82) for preventing an image on the photoreceptor from entering the transfer location upon receipt of the misfeed signal. Transfer of the document image from the photoreceptor to a copy sheet takes place after the misfeed has cleared.

摘要翻译： 一种纸张路径速度分布特征分析装置，利用来自机器纸路径的各种惰轮（82）的输出来检测异常。 惰轮（82）与限定有单独片材通过的辊隙的装置辊（84）摩擦接触。 空转辊（82）联接到编码器（86），用于产生作为惰轮（82）的转速的函数的信号。 将持续监测和瞬时速度读数与在工厂建立的基线速度签名进行比较。 如果持续监控的速度曲线不在工厂设置的预先确定的运行参数内，则启动自动机器调整程序和/或发出自动服务警报。 在整个机器上不断监测速度曲线的能力使得能够进行预防性维护，并且在灾难性故障之前可以更换驱动辊，惰轮和其他运输设备。
