ABSTRACT:
A drive roller and cooperating idler rollers of the friction type are combined to transport or to advance paper or like record media wherein the idler rollers are driven slightly faster than the drive roller. The drive roller has slots or voids in the periphery thereof aligned with the path of travel of the idler rollers to permit an easing or relaxing of the idler roll pressure on the paper and thereby enable the canceling of any accumulated difference in the drive motion between the drive roller and the idler rollers.
