and there is a slight resistance.
b) The clearance between the paper feed roller and the pad narrows

the pressure by moving the friction pad bracket as explained below.
Remove the friction pad bracket fixing screw [E] and loosen the screw [F].
Place the screw [E] in the center position [G] as shown. After adjusting
