It is a lso required when the RADF is dislocated for some re a- son such as moving the equipment. Remove the platen sheet during adjustment. (1) Open the RADF and then attach 2 position- ing pins to the equipment. (The positioning pins have been attached at the rear of the right-hand hinge of the RADF.) Fig.3-50 (2) Close the RADF to check that the positioning pins fit smoothly into the holes on the RADF. If they do not, adjust them according to the following procedure. Fig.3-51 (3) Loosen the stepped screw 1 turn and 2 screws on the adjustment plate a half turn (status of temporary fixing). Fig.3-52 Positioning pin 1 turn Half turn
