8-1-2 Paper feeding system

Paper feeding is performed by conveying the PF(Paper Feed) motor's rotational power from the PF motor
pinion through the Gear reduction and Gear feeding.
Since the Shaft-rubber roller and Roller holder are pressed together, paper advances to the top of the
Rotator ass'y because of the friction between the rubber of the Shaft-rubber roller and the Roller holder.
