A sensor arrangement is provided for sensing the position of an edge of a fed sheet adjacent a front stop. Timing circuitry responsive to the sensor arrangement is used to time a reference time interval from the sensing of the edge. The timing circuitry is coupled to a sheet feeder and is capable of stopping the sheet feeder upon the expiration of the reference time interval. The reference time interval is selected to be sufficiently long to allow the sheet feeder when feeding a sheet to form a buckle in the sheet. The reference time interval is adjustable to provide adjustability of the height of the buckle.

Buckle control system

Apparatus and method for minimizing heating effects and reducing power surges in the fuser element of a copier/duplicator by providing a reduce power, soft turn-on operation during single copy machine cycles followed by a full power turn-on at entry of the copy paper into the fusing station. An adaptive fusing circuit is disclosed so that each of multiple modes of machine operation are properly timed with the fuser soft power-on and full power turn-on features. Available machine modes of operation include chain feeding and large document copying using both a fixed and a movable optical scanning system.
