    Abstract: 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.
