ABSTRACT:
The printing apparatus according to the present invention includes a system for pre-warning of impending shutdown due to slippage of sheets within the printing apparatus sheet transport system. The system includes a plurality of sensors positioned along a sheet transport path for sensing sheets moving along the sheet transport path and a controller for determining an amount and location of slip within the sheet transport path by comparing outputs of the plurality of sensors. Once the location of the slip has been determined, automatic correction may be performed by the printing apparatus or manual correction may be performed by a service representative.
