ABSTRACT:
A printer (1) has paper feed pinch rollers (21, 23 and 25, 27) with their backup rollers canted 5 degrees toward reference guide surface (19). Preceding idler roller (15) is also canted 1.5 degrees toward the guide surface. A sheet (3) fed by D roller (11) first encounters the idler roller and is moved toward the guide surface as a function of its stiffness. Very light sheet slip over the idler roller entirely, while heavier sheets are moved toward the guide surface by the idler roller. The pinch rollers direct all sheets toward guide surface but slip before deforming even very light paper.
