It is mainly performed at the installation. 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).

(6) Remove the positioning pin at the front side.
Close the RADF to fit the positioning pin into  
the hole at the rear side of the RADF. While  
peering inside from the front side, fit the posi- 
tions of the pin and hole by moving the  
RADF right and left.
