Abstract
A system to extend fuser roll life in which image data is varied in its placement on the photoreceptive member and correspondingly, the image receiving substrate position is varied so as to maintain proper location of the image data on the substrate while varying the transverse position of the substrate transverse to the paper path direction. This position varying may take place sheet to sheet or in a job by job arrangement on a printing machine. This varying of lateral position of the sheet causes the high pressure, excessive wear area on the fuser roll to be distributed over a wider area on the roll and not concentrated at a single point at each edge of the sheet. This leads to longer fuser roll life and additionally provides the added benefit of preventing an oil buildup which degrades copies when larger legal size sheets are utilized and/or also preventing associated jams due to the oil buildup at the sheet edge.
