An idler roller assembly in an imaging system including a sheet material transport roller system having drive rollers and idler rollers. The idler roller assembly includes a plurality of idler rollers. A plurality of springs are connected to apply respective normal forces to the idler rollers. Pivoting linkages are provided to equalize the normal forces applied to the respective rollers by respective springs. In an embodiment, the plurality of idler rollers includes a first idler roller and a second idler roller. The plurality of springs includes a first spring connected to apply a normal force to the first idler roller and a second spring connected to apply a normal force to the second idler roller. The pivoting linkage includes a first pivoting lever member connected between the first spring and the second spring.
